WHY READING THIS PROSPECTUS IS IMPORTANT

This prospectus explains the objective, risks, and strategies of each of the
Vanguard International Stock Index Funds. To highlight terms and concepts
important to mutual fund investors, we have provided "Plain Talk(R)"
explanations along the way. Reading the prospectus will help you to decide which
Fund, if any, is the right investment for you. We suggest that you keep it for
future reference.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
IMPORTANT NOTE

Each of the Vanguard International Stock Index Funds offers two separate classes
of shares: Investor and Institutional (except Developed Foreign Markets and
Total International Stock Index Funds, which offer only Investor Shares).
Investor Shares, which have an investment minimum of $3,000 ($1,000 for IRAs),
are offered by two separate prospectuses. This prospectus is intended for
individual investors. There is also a prospectus for participants in
employer-sponsored retirement plans, which you can obtain by calling Vanguard at
1-800-523-1188.

Institutional Shares of Vanguard European, Pacific, and Emerging Markets Stock
Index Funds, in addition to Institutional Developed Foreign Markets Stock Index
Fund, have an investment minimum of $10 million and are generally available to
investors who do not require special employee benefit plan services. These
options are offered by another prospectus, which you can obtain by calling
Vanguard's Institutional Investor Group at 1-800-523-1036.

Note that the Funds' separate share classes have different expenses; as a
result, their investment performances will vary.

- --------------------------------------------------------------------------------

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

AN INTRODUCTION TO INDEX FUNDS

WHAT IS INDEXING?
An index is an unmanaged group of securities whose overall performance is used
as a standard to measure investment performance. An index (or "passively
managed") fund tries to track, as closely as possible, the performance of an
established target index. The fund does this by holding all, or a representative
sample, of the securities that comprise the index. Keep in mind that an index
fund has operating expenses and transaction costs, while a market index does
not. Therefore, an index fund, while expected to track its target index closely,
typically will be unable to match the performance of the index exactly.
Stock index funds may seek to track indexes that hold a certain type of
stock--such as growth or value, small-cap or large-cap, or those from just one
industry--or they may seek to track indexes that consist of a broader range of
stocks--for example, the entire foreign stock market.
Index funds are not actively managed by investment advisers who buy and
sell securities based on research and analysis in an attempt to outperform a
particular benchmark or the market as a whole. Rather, index funds simply
attempt to mirror what the target index does, for better or worse.

WHAT INDEX FUNDS DOES VANGUARD OFFER?

Vanguard offers a variety of stock (both U.S. and international), bond, and
balanced index funds. This prospectus provides information about Vanguard's
International Stock Index Funds. There are five such funds, each of which seeks
to track a different segment of the international stock market:

FUND SEEKS TO TRACK
- -----------------------------------------------------------------------------
Vanguard European Stock Index Fund European stock markets
Vanguard Pacific Stock Index Fund Australian and Far East stock
markets
Vanguard Emerging Markets Stock 13 emerging stock markets in
Index Fund Europe, Asia, Africa, and
Latin America
Vanguard Developed Foreign Markets Stock European, Australian, and Far
Index Fund East stock markets
Vanguard Total International Stock European, Australian, Far East,
Index Fund and 13 emerging stock
markets in Europe, Asia,
Africa, and Latin America

This prospectus contains profiles that summarize key features of each Fund.
Following the profiles, there is important additional information about the
Funds.

<PAGE>

FUND PROFILE--
VANGUARD EUROPEAN STOCK INDEX FUND

The following profile provides you with a summary of the key features of
Vanguard European Stock Index Fund.

INVESTMENT OBJECTIVE

The Fund seeks to match the performance of the Morgan Stanley Capital
International (MSCI) Europe Index, which is made up of approximately 550 common
stocks of companies located in 15 European countries--mostly in the United
Kingdom, Germany, Switzerland, and France, (which comprised xx%, xx%, xx%, and
xx% of the Index's market capitalization, respectively, as of December 31,
1999), as well as in Austria, Belgium, Denmark, Finland, Ireland, Italy, the
Netherlands, Norway, Portugal, Spain, and Sweden.

INVESTMENT STRATEGIES
The Fund employs a "passively managed"--or index--investment approach, by
holding a mix of common stocks included in the MSCI Europe Index. For more
information about passive management, see "Indexing Methods" under MORE ON THE
FUNDS.

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS. The
Fund is also subject to:
- - Country risk, which is the chance that a country's economy will be hurt by
political troubles, financial problems, or natural disasters.
- - Regional risk, which is the chance that an entire region--namely
Europe--will be hurt by political troubles, financial problems, or natural
disasters.
- - Currency risk, which is the chance that returns will be hurt by a rise in
the value of the U.S. dollar versus foreign currencies.
- - Investment style risk, which is the chance that returns from foreign stocks
will trail returns from other asset classes or the overall stock market.

PERFORMANCE/RISK INFORMATION

The bar chart and table below provide an indication of the risk of investing in
the Fund. The bar chart shows the Fund's performance in each calendar year since
inception. The table shows how the Fund's average annual total returns for one
and five calendar years and since inception compare with those of a broad-based
securities market index. Keep in mind that the Fund's past performance does not
indicate how it will perform in the future.

FEES AND EXPENSES
The following table describes the fees and expenses you would pay if you buy and
hold shares of the Fund. The expenses shown under Annual Fund Operating Expenses
are based upon those incurred in the fiscal year ended December 31, 1999.

SHAREHOLDER FEES (fees paid directly from your investment)
Sales Charge (Load) Imposed on Purchases: None
Transaction Fee on Purchases: 0.5%*
Sales Charge (Load) Imposed on Reinvested Dividends: None

The following example is intended to help you compare the cost of investing
in the Fund with the cost of investing in other mutual funds. It illustrates the
hypothetical expenses that you would incur over various periods if you invest
$10,000 in the Fund. This example assumes that the Fund provides a return of 5%
a year, and that operating expenses remain the same. The results apply whether
or not you redeem your investment at the end of each period.

consists of approximately 420 common stocks of companies located in Japan (which
comprised xx% of the Index's market capitalization as of December 31,1999),
Australia, Hong Kong, New Zealand, and Singapore.

*The designation "Free" in the name of the Index refers to the securities that
the index tracks. Some countries restrict foreign investment in certain
industries, so only stocks that can be bought freely by a fund are tracked.

INVESTMENT STRATEGIES

The Fund employs a "passively managed"--or index--investment approach, by
holding a mix of common stocks included in the MSCI Pacific Free Index. For more
information about passive management, see "Indexing Methods" under MORE ON THE
FUNDS.

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS. The
Fund is also subject to:
- - Country risk, which is the chance that a country's economy will be hurt by
political troubles, financial problems, or natural disasters.
- - Regional risk, which is the chance that an entire region--namely the
Pacific region--will be hurt by political troubles, financial problems, or
natural disasters.
- - Currency risk, which is the chance that returns will be hurt by a rise in
the value of the U.S. dollar versus foreign currencies.
- - Investment style risk, which is the chance that returns from foreign stocks
will trail returns from other asset classes or the overall stock market.

FUND PROFILE--
VANGUARD EMERGING MARKETS STOCK INDEX FUND

The following profile summarizes key features of Vanguard Emerging Markets Stock
Index Fund.

INVESTMENT OBJECTIVE

The Fund seeks to match the performance of the Select Emerging Markets Free
Index*, which includes approximately 500 common stocks of companies located in
13 emerging markets of Europe, Asia, Africa, and Latin America--mostly in

as Argentina, the Czech Republic, Greece, Hungary, Indonesia, Israel,
Philippines, Poland, Thailand, and Turkey. The developed countries of Hong Kong
and Singapore are included in the Index to broaden diversification and ensure
adequate liquidity.

<PAGE>

INVESTMENT STRATEGIES

The Fund employs a "passively managed"--or index--investment approach, by
holding a mix of common stocks included in the Select Emerging Markets Free
Index. For more information about passive management, see "Indexing Methods"
under MORE ON THE FUNDS.

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS. The
Fund is also subject to:
- - Country risk, which is the chance that a country's economy will be hurt by
political troubles, financial problems, or natural disasters. Country risk
is especially high for funds that focus on stocks in emerging markets.
- - Currency risk, which is the chance that returns will be hurt by a rise in
the value of the U.S. dollar versus foreign currencies.
- - Investment style risk, which is the chance that returns from foreign stocks
will trail returns from other asset classes or the overall stock market.

FUND PROFILE--
VANGUARD TOTAL INTERNATIONAL STOCK INDEX FUND

The following profile summarizes key features of Vanguard Total International
Stock Index Fund.

INVESTMENT OBJECTIVE
The Fund seeks to match the performance of the Total International Composite
Index, which is a combination of the indexes tracked by the European, Pacific,
and Emerging Markets Stock Index Funds.

INVESTMENT STRATEGIES

The Fund employs a "passively managed"--or index--investment approach, by
holding a mix of mutual funds that together seek to match the performance of the
Total International Composite Index. As a "fund of funds," the Fund invests in
Vanguard's European, Pacific, and Emerging Markets Stock Index Funds, in
proportions based on each market segment's contribution to the market
capitalization of the Total International Composite Index. For more information
about passive management, see "Indexing Methods" under MORE ON THE FUNDS.

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS. The
Fund is also subject to:
- - Country risk, which is the chance that a country's economy will be hurt by
political troubles, financial problems, or natural disasters.
- - Currency risk, which is the chance that returns will be hurt by a rise in
the value of the U.S. dollar versus foreign currencies.
- - Investment style risk, which is the chance that returns from foreign stocks
will trail returns from other asset classes or the overall stock market.

MORE ON THE FUNDS

The following sections discuss other important features of Vanguard
International Stock Index Funds, including indexing methods, fund
characteristics, additional risk information, costs and market-timing, fund
turnover, and other investment policies and risks.

WHY INVEST IN INDEX FUNDS?
Index funds appeal to many investors for a number of reasons:
- - Diversification. Index funds generally invest in a diversified mix of
companies and industries.
- - Relative consistency. Index funds typically track the performance of
relevant market benchmarks more closely than comparable actively managed
funds do.
- - Low cost. Index funds do not have many of the expenses of an actively
managed fund--such as research--and keep trading activity, and thus
brokerage commissions, to a minimum.
- - Low realization of capital gains. Because an index fund typically sells
securities only to respond to redemption requests or to adjust the number
of shares it holds to reflect a change in its target index, the fund's
turnover rate--and thus its realization of capital gains--is usually very
low.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
THE COSTS OF INVESTING

Costs are an important consideration in choosing a mutual fund. That's because
you, as a shareholder, pay the costs of operating a fund, plus any transaction
costs associated with the fund's buying and selling of securities. These costs
can erode a substantial portion of the gross income or capital appreciation a
fund achieves. Even seemingly small differences in expenses can, over time, have
a dramatic effect on a fund's performance.
- --------------------------------------------------------------------------------

INDEXING METHODS
In seeking to track a particular index, a fund may use one of two indexing
methods to select the stocks it invests in.
Some index funds hold each stock found in their target indexes in about the
same proportions as represented in the indexes themselves. For example, if 5% of
the S&P 500 Index were made up of the stock of a specific company, a fund
tracking that index would invest about 5% of its assets in that company.

Other index funds may use a different selection process. Because it would
be very expensive to buy all of the stocks held in certain indexes (the Select
Emerging Markets Free Index, for example, includes approximately 500 stocks),
funds tracking these larger indexes use a "sampling" technique. Using a
sophisticated computer program, these funds invest in stocks that will recreate
their target indexes in terms of industry, size, country, and other
characteristics. For instance, if 10% of the Select Emerging Markets Free Index
were made up of the stocks of a certain country, the Emerging Markets Stock
Index Fund would invest about 10% of its assets in stocks of the Index from that
country. The European, Pacific, and Emerging Markets Stock Index Funds each
employ this method of indexing. As a "fund of funds," the Total International
Stock Index Fund allocates its assets among the European, Pacific, and Emerging
Markets Stock Index Funds. The Developed Foreign Markets Stock Index Fund, which
is also a "fund of funds," allocates its assets among the European and Pacific
Stock Index Funds.

PLAIN TALK ABOUT
"FUND OF FUNDS"

The term "fund of funds" is used to describe a mutual fund that pursues its
objective by investing in other mutual funds rather than in individual stocks or
bonds. A fund of funds may charge for its own direct expenses, in addition to
bearing a proportionate share of the expenses charged by the underlying funds in
which it invests. Funds of funds are best suited for long-term investors.
- --------------------------------------------------------------------------------

ADDITIONAL RISK INFORMATION

To track their target indexes as closely as possible, the European and Pacific
Stock Index Funds attempt to remain fully invested in foreign stocks included in
their particular indexes. The Emerging Markets Stock Index Fund normally invests
95% of its assets in foreign stocks, holding the remaining 5% in cash reserves
to meet daily redemption requests. The Total International and Developed Foreign
Markets Stock Index Funds normally hold 100% of their assets in shares of their
underlying funds.

PLAIN TALK ABOUT
THE RISKS OF INTERNATIONAL INVESTING

Because foreign stock and bond markets operate differently from the U.S. market,
Americans investing abroad will encounter risks not typically associated with
U.S. companies. For instance, foreign companies are not subject to the same
accounting, auditing, and financial reporting standards and practices as U.S.
companies; and their stocks may not be as liquid as those of similar U.S.
companies. In addition, foreign stock exchanges, brokers, and companies
generally have less government supervision and regulation than their
counterparts in the United States. These factors, among others, could negatively
impact the returns Americans receive from foreign investments.
- --------------------------------------------------------------------------------

[FLAG] EACH FUND IS SUBJECT TO STOCK MARKET RISK, WHICH IS THE CHANCE THAT STOCK
PRICES OVERALL WILL DECLINE OVER SHORT OR EVEN LONG PERIODS. STOCK MARKETS
TEND TO MOVE IN CYCLES, WITH PERIODS OF RISING PRICES AND PERIODS OF
FALLING PRICES.
IN ADDITION, INVESTMENTS IN FOREIGN STOCK MARKETS CAN BE RISKIER THAN
U.S. STOCK INVESTMENTS. THE PRICES OF INTERNATIONAL STOCKS AND THE PRICES
OF U.S. STOCKS HAVE OFTEN MOVED IN OPPOSITE DIRECTIONS. THESE PERIODS HAVE,
IN THE PAST, LASTED FOR AS LONG AS SEVERAL YEARS.

To illustrate the volatility of international stock prices, the following
table shows the best, worst, and average total returns for foreign stock markets
over various periods as measured by the MSCI EAFE Index, a widely used barometer
of international market activity. (Total returns consist of dividend income plus
change in market price.) Note that the returns shown do not include the costs of
buying and selling stocks or other expenses that a real-world investment
portfolio would incur. Note, also, that the gap between best and worst tends to
narrow over the long term.

The table covers all of the 1-, 5-, 10-, and 20-year periods from 1969

stock markets. These average returns reflect past performance on international
stocks; you should not regard them as an indication of future returns from
either foreign markets as a whole or any of the Funds in particular.
Note that the preceding chart does not take into account returns measured
by the MSCI Emerging Markets Free Index, a widely used barometer of less
developed stock markets. Emerging markets can be substantially more volatile
than more developed foreign markets. In addition, because the MSCI EAFE Index
tracks the European and Pacific markets collectively, the above returns do not
reflect the variability of returns from year to year for these markets
individually, or the variability across these and other geographic regions or
market sectors. To illustrate this variability, the following table shows
returns for different international markets--as well as the U.S. market for
comparison--from 1990-1999, as measured by their respective indexes. Note that
the returns shown do not include the costs of buying and selling stocks or other

PLAIN TALK ABOUT
REGIONAL VERSUS BROAD INTERNATIONAL INVESTING

Regional funds are international funds that invest in a particular geographical
region, such as Europe or the Pacific Basin. Because they concentrate their
holdings in a single region, these funds typically have higher share price
volatility than broadly diversified international stock funds (which, by
investing in many different foreign markets, may offset losses from one country
with gains from another at any given time).
- --------------------------------------------------------------------------------

EUROPEAN STOCK INDEX FUND. Stocks from the United Kingdom, Germany,
Switzerland and France comprised xx%, xx%, xx%, and xx% of the MSCI Europe
Index, respectively, as of December 31, 1999; stocks from the remaining 11
countries in the Index have much less significant market capitalization
weightings in the Index and thus much less impact on its total return. The
Fund's heavy exposure to just four countries involves a higher degree of country
risk than that of more geographically diversified international funds.
PACIFIC STOCK INDEX FUND. Japanese stocks comprised xx% of the MCSI Pacific
Free Index as of December 31, 1999. Therefore, Japanese stocks will represent a
correspondingly large component of the Pacific Stock Index Fund's assets. The
Fund's large investment in the Japanese stock market may involve a higher degree
of country risk than that of more geographically diversified international
funds.

EMERGING MARKETS STOCK INDEX FUND. As discussed above, emerging markets can
be substantially more volatile than both U.S and more developed foreign markets.
Therefore, the Emerging Markets Stock Index Fund may expose investors to a
higher degree of volatility than funds that invest in more developed markets.

DEVELOPED FOREIGN MARKETS STOCK INDEX FUND. As a fund of funds, the
Developed Foreign Markets Stock Index Fund intends to invest all of its assets
in shares of the European and Pacific Stock Index Funds; indirectly, its country
risk will proportionately mirror that of the European and Pacific Stock Index
Funds.
TOTAL INTERNATIONAL STOCK INDEX FUND. As a fund of funds, the Total
International Stock Index Fund intends to invest all of its assets in shares of
the European, Pacific, and Emerging Markets Stock Index Funds; indirectly, its
country risk will proportionately mirror that of the underlying funds. As of
December 31, 1999, the Fund's assets were invested as follows: xx% in the
European Stock Index Fund; xx% in the Pacific Stock Index Fund; and xx% in the
Emerging Markets Stock Index Fund.

[FLAG] EACH FUND IS SUBJECT TO CURRENCY RISK, WHICH IS THE POSSIBILITY THAT A

SECURITY SELECTION

In seeking to track its target index, the European Stock Index, Pacific Stock
Index, and Emerging Markets Stock Index Funds each invest in a portfolio of
foreign stocks selected through statistical methods. The Total International
Stock Index Fund simply invests in shares of the European, Pacific, and Emerging
Markets Stock Index Funds. Likewise, the Developed Foreign Markets Stock Index
Fund will simply invest in shares of the European and Pacific Stock Index Funds.
EUROPEAN STOCK INDEX FUND. The Fund invests in a statistically selected
sample of approximately 550 common stocks included in the MSCI Europe Index,
which is made up of the stocks of companies located in 15 European countries.
Four countries--the United Kingdom, Germany, Switzerland, and France--dominate
the Index, with xx%, xx%, xx%, and xx%, respectively, as of December 31, 1999.
The other 11 countries, which include Austria, Belgium, Denmark, Finland,
Ireland, Italy, the Netherlands, Norway, Portugal, Spain, and Sweden, are much
less significant to the Index and, consequently, the Fund.
PACIFIC STOCK INDEX FUND. The Fund invests in a statistically selected
sample of the approximately 420 common stocks included in the MSCI Pacific Free
Index, which is comprised of the stocks of Pacific Basin companies. The Index is
dominated by the Japanese stock market, which represented xx% of the market
capitalization of the Index as of December 31, 1999. The other four countries
represented in the Index are Australia, Hong Kong, New Zealand, and Singapore.
EMERGING MARKETS STOCK INDEX FUND. The Fund invests in a statistically
selected sample of the approximately 500 common stocks included in the Select
Emerging Markets Free Index, which is made up of the stocks of companies located
in 13 emerging markets of Europe, Asia, Africa, and Latin America. Three
countries--Brazil, Mexico, and South Africa--represent a majority of the Index,
with xx%, xx%, and xx% of the market capitalization of the Index, respectively,
as of December 31, 1999. The other 10 countries include Argentina, the Czech
Republic, Greece, Hungary, Indonesia, Israel, Philippines, Poland, Thailand, and
Turkey. The developed countries of Hong Kong and Singapore are included in the
Index to broaden diversification and ensure adequate liquidity.

Although index funds, by their nature, tend to be tax-efficient investment
vehicles, the Funds are generally managed without regard to tax ramifications.

TRANSACTION FEES AND ACCOUNT MAINTENANCE FEES
Some of Vanguard's index funds charge a transaction fee on purchases of fund
shares to offset the higher costs of trading certain securities, particularly
small-company and international stocks. The transaction fee ensures that these
higher costs are borne by the investors making the transactions--and not by
shareholders already in the fund. In addition, most of Vanguard's index funds
charge an account maintenance fee on accounts under $10,000 to divide the costs
of maintaining accounts equitably among shareholders.
All transaction fees are paid directly to the fund itself (unlike a sales
charge or load, which--for many fund companies--ends up in the pocket of the
sponsor, adviser, or sales representative). Without transaction fees, some index
funds would have trouble tracking their target indexes.
Vanguard assesses an account maintenance fee on index fund shareholders
whose account balances are below $10,000 (for any reason, including a decline in
the value of a fund's shares) on the date a dividend is distributed. This fee is
intended to allocate the costs of maintaining accounts more equitably among
shareholders. For funds that distribute dividends annually, the account
maintenance fee is $10 per year, deducted from the annual dividend, which
usually is distributed during the last two weeks of the calendar year.

<PAGE>

If the fee is deducted from your dividend distribution, you will still be taxed
on the full amount of your dividend (unless you hold your shares through a
nontaxable account). If you are due a dividend that is less than the fee,
fractional shares will be automatically redeemed to make up the difference.

COSTS AND MARKET-TIMING

Some investors try to profit from a strategy called market-timing--switching
money into investments when they expect prices to rise, and taking money out
when they expect prices to fall. As money is shifted in and out, a fund incurs
expenses for buying and selling securities. These costs are borne by all fund
shareholders, including the long-term investors who do not generate the costs.
Therefore, the Vanguard International Stock Index Funds have adopted the
following policies, among others, designed to discourage short-term trading:
- - Each Fund reserves the right to reject any purchase request--including
exchanges from other Vanguard funds--that it regards as disruptive to the
efficient management of the Fund. A purchase request could be rejected
because of the timing of the investment or because of a history of
excessive trading by the investor.

- - Each Fund (except the Developed Foreign Markets Stock Index Fund) charges a
transaction fee on purchases. In addition, the Emerging Markets Stock Index
Fund charges a transaction fee on redemptions.

- - Telephone and online exchanges are not accepted for non-IRA accounts.
- - There is a limit on the number of times you can exchange into and out of a
Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).
- - Each Fund reserves the right to stop offering shares at any time.

THE VANGUARD FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE
FUNDS IF YOU ARE A MARKET-TIMER.

TURNOVER RATE

Although each Fund seeks to invest for the long term, the Funds retain the right
to sell securities regardless of how long the securities have been held.
Generally, a passively-managed fund sells securities only to respond to
redemption requests or to adjust the number of shares held to reflect a change
in the fund's target index. Because of this, the turnover rate for each Fund has
been extremely low. The Financial Highlights tables beginning on page 25 show
historic turnover rates for each Fund.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
TURNOVER RATE

Before investing in a mutual fund, you should review its turnover rate. This
gives an indication of how transaction costs could affect the fund's future
returns. In general, the greater the volume of buying and selling by the fund,
the greater the impact that brokerage commissions and other transaction costs
will have on its return. Also, funds with high turnover rates may be more likely
to generate capital gains that must be distributed to shareholders as income
subject to taxes. According to Morningstar, Inc. as of December 31, 1999, the
average turnover rate for passively managed foreign stock index funds was
roughly xx%; for all foreign stock funds, the average turnover was approximately
xx%. (A turnover rate of 100% would occur, for example, if a fund sold and
replaced securities valued at 100% of its net assets within a one-year period.)

- --------------------------------------------------------------------------------

<PAGE>

OTHER INVESTMENT POLICIES AND RISKS

Besides investing in common stocks of foreign companies, each Fund may make
certain other kinds of investments to achieve its objective. Each Fund may
change its objective without shareholder approval.
The Funds may also invest, to a limited extent, in futures and options
contracts, warrants, convertible securities, and swap agreements, which are
types of derivatives. Losses (or gains) involving futures contracts can
sometimes be substantial--in part because a relatively small price movement in a
futures contract may result in an immediate and substantial loss (or gain) for a
fund. Similar risks exist for warrants (securities that permit their owners to
purchase a specific number of shares of stock at a predetermined price),
convertible securities (securities that may be exchanged for another asset), and
swap agreements (contracts between two parties in which each agrees to make
payments to the other based on the return of a specified index or asset).

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
DERIVATIVES

A derivative is a financial contract whose value is based on (or "derived" from)
a traditional security (such as a stock or a bond), an asset (such as a
commodity like gold), or a market index (such as the S&P 500 Index). Futures and
options are derivatives that have been trading on regulated exchanges for more
than two decades. These "traditional" derivatives are standardized contracts
that can easily be bought and sold, and whose market values are determined and
published daily. It is these characteristics that differentiate futures and
options from the relatively new types of derivatives. If used for speculation or
as leveraged investments, derivatives can carry considerable risks.
- --------------------------------------------------------------------------------

For this reason, the Funds will not use futures, options, warrants,
convertible securities, or swap agreements for speculative purposes or as
leveraged investments that magnify the gains or losses of an investment. A
Fund's obligation under futures contracts will not exceed 20% of its total
assets.
The reasons for which a Fund will invest in futures and options are:
- - To keep cash on hand to meet shareholder redemptions or other needs while
simulating full investment in stocks.
- - To reduce the Fund's transaction costs or add value when these instruments
are favorably priced.
Each Fund may also enter into forward foreign currency contracts in order
to maintain the same currency exposure as its respective Index. A forward
foreign currency contract is an agreement to buy or sell a country's currency at
a specific price on a specific date, usually 30, 60, or 90 days in the future.
In other words, the contract guarantees an exchange rate on a given date.
Managers of international stock funds typically use these contracts to guard
against sudden, unfavorable changes in U.S. dollar/foreign currency exchange
rates. However, the Funds will use these contracts for different reasons:
- - To gain currency exposure when investing in futures.
- - To settle trades in a foreign currency.

PLAIN TALK ABOUT
VANGUARD'S UNIQUE CORPORATE STRUCTURE

The Vanguard Group is truly a MUTUAL mutual fund company. It is owned jointly by
the funds it oversees and thus indirectly by the shareholders in those funds.
Most other mutual funds are operated by for-profit management companies that may
be owned by one person, by a group of individuals, or by investors who own the
management company's stock. By contrast, Vanguard provides its services on an
"at-cost" basis, and the funds' expense ratios reflect only these costs. No
separate management company reaps profits or absorbs losses from operating the
funds.
- --------------------------------------------------------------------------------

THE FUNDS AND VANGUARD

Vanguard International Stock Index Funds are offered by The Vanguard Group, a
family of more than 35 investment companies with more than 100 funds holding
assets worth more than $xxx billion. All of the Vanguard funds share in the
expenses associated with business operations, such as personnel, office space,
equipment, and advertising.

Vanguard also provides marketing services to the funds. Although
shareholders do not pay sales commissions or 12b-1 distribution fees, each fund
pays its allocated share of The Vanguard Group's marketing costs.

Total International and Developed Foreign Markets Stock Index Funds will
indirectly bear a proportionate share of the expenses of the underlying funds in
which they invest. However, their direct expenses are expected to be very low or
zero. For example, Total International Stock Index Fund has incurred no direct
expenses since its inception in 1996. Total International and Developed Foreign
Markets Stock Index Funds may operate without incurring direct expenses because
Vanguard will reimburse them for (i) their contributions to the cost of
operating the underlying funds in which they invest, and (ii) savings in
administrative and marketing costs that Vanguard expects to derive from their
operations.

INVESTMENT ADVISER

The Vanguard Group (Vanguard), P.O. Box 2600, Valley Forge, PA 19482, founded in
1974, serves as the Funds' adviser through its Core Management Group. (The
Developed Foreign Markets and Total International Stock Index Funds receive
advisory services indirectly, by investing in the other three Funds.) Vanguard
manages the Funds on an at-cost basis, subject to the control of the Trustees
and officers of the Funds. For the fiscal year ended December 31, 1999, the
advisory fees represented an effective annual rate of less than 0.01% each for
the European, Pacific, and Emerging Markets Stock Index Funds.
The Funds have authorized Vanguard to choose brokers or dealers to handle
the purchase and sale of securities for the Funds, and to get the best available
price and most favorable execution from these brokers or dealers with respect to
all transactions. The Funds may direct Vanguard to use a particular broker for
certain transactions in exchange for commission rebates or research services
provided to the Funds.

DIVIDENDS, CAPITAL GAINS, AND TAXES

FUND DISTRIBUTIONS
Each Fund distributes to shareholders virtually all of its net income (interest
and dividends, less expenses), as well as any capital gains realized from the
sale of its holdings. Distributions generally occur in December. In addition, a
Fund may occasionally be required to make supplemental dividend or capital gains
distributions at some other time during the year. You can receive distributions
of income dividends or capital gains in cash, or you can have them automatically
reinvested in more shares of the Fund.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
DISTRIBUTIONS

As a shareholder, you are entitled to your share of the fund's income from
interest and dividends, and gains from the sale of investments. You receive such
earnings as either an income dividend or a capital gains distribution. Income
dividends come from both the dividends that the fund earns from its holdings and
the interest it receives from its money market and bond investments. Capital
gains are realized whenever the fund sells securities for higher prices than it
paid for them. These capital gains are either short-term or long-term depending
on whether the fund held the securities for one year or less, or more than one
year.
- --------------------------------------------------------------------------------

BASIC TAX POINTS
Vanguard will send you a statement each year showing the tax status of all your
distributions. In addition, taxable investors should be aware of the following
basic tax points:
- - Distributions are taxable to you whether or not you reinvest these amounts
in additional Fund shares.
- - Distributions declared in December--if paid to you by the end of
January--are taxable as if received in December.
- - Any dividends and short-term capital gains that you receive are taxable to
you as ordinary income for federal income tax purposes.
- - Any distributions of net long-term capital gains are taxable to you as
long-term capital gains for federal income tax purposes, no matter how long
you've owned shares in the Fund.
- - Capital gains distributions may vary considerably from year to year as a
result of the Funds' normal investment activities and cash flows.

<PAGE>

- - A sale or exchange of Fund shares is a taxable event. This means that you
may have a capital gain to report as income, or a capital loss to report as
a deduction, when you complete your federal income tax return.
- - State and local income taxes may apply to any dividend or capital gains
distributions that you receive, as well as to your gains or losses from any
sale or exchange of Fund shares.
- - The European, Pacific, and Emerging Markets Stock Index Funds each may be
subject to foreign taxes or foreign tax withholding on dividends, interest,
and some capital gains that it receives on foreign securities. You may
qualify for an offsetting credit or deduction under U.S. tax laws for your
portion of a Fund's foreign tax obligations, provided that you meet certain
requirements. Because the Total International and Developed Foreign Markets
Stock Index Funds invest in foreign stocks indirectly through the other
three Funds, their investors are not able to take advantage of foreign tax
credits or deductions. See your tax adviser or IRS publications for more
information.

GENERAL INFORMATION
BACKUP WITHHOLDING. By law, Vanguard must withhold 31% of any taxable
distributions or redemptions from your account if you do not provide us with
your correct taxpayer identification number and certify that it is correct.
Similarly, Vanguard must withhold from your account if the IRS instructs us to
do so.
FOREIGN INVESTORS. The Vanguard funds generally do not offer their shares for
sale outside of the United States. Foreign investors should be aware that U.S.
withholding and estate taxes may apply to any investments in Vanguard funds.
INVALID ADDRESSES. If a dividend or capital gains distribution check mailed to
your address of record is returned as undeliverable, Vanguard will automatically
reinvest all future distributions until you provide us with a valid mailing
address.
TAX CONSEQUENCES. This prospectus provides general tax information only. If you
are investing through a tax-deferred retirement account, such as an IRA, special
tax rules apply. Please consult your tax adviser for detailed information about
a fund's tax consequences for you.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
"BUYING A DIVIDEND"

Unless you are investing through a tax-deferred retirement account (such as an
IRA), you should avoid buying shares of a fund shortly before it makes a
distribution, because doing so can cost you money in taxes. This is known as
"buying a dividend." For example: On December 15, you invest $5,000, buying 250
shares for $20 each. If the fund pays a distribution of $1 per share on December
16, its share price would drop to $19 (not counting market change). You still
have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1
= $250 in distributions), but you owe tax on the $250 distribution you
received--even if you reinvest it in more shares. To avoid "buying a dividend,"
check a fund's distribution schedule before you invest.
- --------------------------------------------------------------------------------

<PAGE>

SHARE PRICE

Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of regular trading on the New York Stock Exchange
(the NAV is not calculated on holidays or other days when the Exchange is
closed). Net asset value per share for the Developed Foreign Markets and Total
International Stock Index Funds is computed by adding up the total value of the
Fund's investments (i.e., shares of the underlying funds) and other assets,
subtracting any of its liabilities (debts), and then dividing by the number of
Fund shares outstanding:

TOTAL ASSETS - LIABILITIES
NET ASSET VALUE = --------------------------------
NUMBER OF SHARES OUTSTANDING

Knowing the daily net asset value is useful to you as a shareholder because
it indicates the current value of your investment. The Fund's NAV, multiplied by
the number of shares you own, gives you the dollar amount you would have
received had you sold all of your shares back to the Fund that day. Because
foreign securities markets may operate on days which are not business days in
the United States, the value of a Fund's holdings may change on days when
shareholders will not be able to purchase or redeem the Fund's shares.
A NOTE ON PRICING: A Fund's investments will be priced at their market
value when market quotations are readily available. When these quotations are
not readily available, investments will be priced at their fair value,
calculated according to procedures adopted by the Funds' Board of Trustees. A
Fund also may use fair value pricing if the value of a security held by the Fund
is materially affected by events occurring after the close of the primary
markets or exchanges on which such security is traded. In these situations,
prices used by the Fund to calculate its net asset value may differ from quoted
or published prices for the underlying securities.

Each Fund's share price can be found daily in the mutual fund listings of
most major newspapers under the heading "Vanguard Index Funds." Different
newspapers use different abbreviations for each Fund, but the most common are
EUROPE, PACIFIC, EMERMKT, XXXX, and TOTINTL for the European, Pacific, Emerging
Markets, Developed Foreign Markets, and Total International Stock Index Funds,
respectively.

FINANCIAL HIGHLIGHTS

The following financial highlights tables are intended to help you understand
each Fund's financial performance for the past five years or since inception
(except for the Developed Foreign Markets Stock Index Fund, which did not start
operations until May xx, 2000), and certain information reflects financial
results for a single Fund share. The total returns in each table represent the
rate that an investor would have earned or lost each year on an investment in
the Fund (assuming reinvestment of all dividends and capital gains
distributions). This information has been derived from the financial statements
audited by PricewaterhouseCoopers LLP, independent accountants, whose
report--along with each Fund's financial statements--is included in the Funds'
most recent annual report to shareholders. You may have the annual report sent
to you without charge by contacting Vanguard.

PLAIN TALK ABOUT
HOW TO READ THE FINANCIAL HIGHLIGHTS TABLE

This explanation uses the European Stock Index Fund as an example. The Fund
began fiscal 1999 with a net asset value (price) of $25.28 per share. During the
year, the Fund earned $0.xx per share from investment income (interest and
dividends) and $x.xx per share from investments that had appreciated in value or
that were sold for higher prices than the Fund paid for them.

Shareholders received $0.xx per share in the form of dividend and capital gains
distributions. A portion of each year's distributions may come from the prior
year's income or capital gains.

The earnings ($x.xx per share) minus the distributions ($0.xx per share)
resulted in a share price of $xx.xx at the end of the year. This was an increase
of $x.xx per share (from $25.28 at the beginning of the year to $xx.xx at the
end of the year). For a shareholder who reinvested the distributions in the
purchase of more shares, the total return from the Fund was xx.xx% for the year.

As of December 31, 1999, the Fund had $x.x billion in net assets. For the year,
its expense ratio was 0.xx% ($x.x0 per $1,000 of net assets); and its net

- --------------------------------------------------------------------------------
A NOTE ON LARGE PURCHASES
It is important that you call Vanguard before you invest a large dollar amount.
It is our responsibility to consider the interests of all Fund shareholders, and
so we reserve the right to refuse any purchase that may disrupt the Fund's
operation or performance.
- --------------------------------------------------------------------------------

REDEEMING SHARES

This section describes how you can redeem--that is, sell or exchange--the Fund's
shares.

When Selling Shares:
- - Vanguard sends the redemption proceeds to you or a designated third party.*
- - You can sell all or part of your Fund shares at any time.

*May require a signature guarantee; see footnote on page 35.

- - In order to exchange into an account with a different registration
(including a different name, address, or taxpayer identification number),
you must include the guaranteed signature of all current account owners on
your written instructions.

- --------------------------------------------------------------------------------
A NOTE ON REDEMPTION FEES
Emerging Markets Stock Index Fund imposes a 1% redemption fee on all share
redemptions. Currently, redemption fees do not apply to Fund shares held through
Vanguard's separate recordkeeping system for employee benefit plan accounts, due
to certain economies associated with these accounts. However, the Fund reserves
the right to impose redemption fees on its shares at any time if warranted by
the Fund's future costs of processing redemptions from these accounts.
- --------------------------------------------------------------------------------

NOTE: Once a redemption is initiated and a confirmation number given, the
transaction CANNOT be canceled.

- --------------------------------------------------------------------------------

<PAGE>

HOW TO REQUEST A REDEMPTION
You can request a redemption from your Fund account in any one of three ways:
online, by telephone, or by mail.

The Vanguard funds whose shares you cannot exchange online or by telephone
are VANGUARD U.S. STOCK INDEX FUNDS, VANGUARD BALANCED INDEX FUND, VANGUARD
INTERNATIONAL STOCK INDEX FUNDS, VANGUARD REIT INDEX FUND, and VANGUARD GROWTH
AND INCOME FUND. These funds do, however, permit online and telephone exchanges
within IRAs and some other retirement accounts. If you sell shares of these
funds online, you will receive a redemption check at your address of record.
- --------------------------------------------------------------------------------
ONLINE REQUESTS [COMPUTER ICON]
ACCESS VANGUARD at www.vanguard.com
You can use your personal computer to sell or exchange shares of most Vanguard
funds by accessing our website. To establish this service, you must register

transactions).

- --------------------------------------------------------------------------------

TELEPHONE REQUESTS [TELEPHONE ICON]

- --------------------------------------------------------------------------------
SPECIAL INFORMATION: We will automatically establish the telephone redemption
option for your account, unless you instruct us otherwise in writing. While
telephone redemption is easy and convenient, this account feature involves a
risk of loss from unauthorized or fraudulent transactions. Vanguard will take
reasonable precautions to protect your account from fraud. You should do the
same by keeping your account information private and immediately reviewing any
account statements that we send to you. Make sure to contact Vanguard
immediately about any transaction you believe to be unauthorized.
- --------------------------------------------------------------------------------
We reserve the right to refuse a telephone redemption if the caller is unable to
provide:
- - The ten-digit account number.
- - The name and address exactly as registered on the account.
- - The primary Social Security or employer identification number as registered
on the account.

- - The Personal Identification Number (PIN), if applicable (for instance,
Tele-Account).

<PAGE>

circumstances as determined by the U.S. Securities and Exchange Commission. If
you experience difficulty making a telephone redemption during periods of
drastic economic or market change, you can send us your request by regular or
express mail. Follow the instructions on selling or exchanging shares by mail in
this section.
- --------------------------------------------------------------------------------
MAIL REQUESTS [ENVELOPE ICON]
All Account Types Except Retirement:
Send a letter of instruction signed by all registered account holders. Include
the fund name and account number and (if you are selling) a dollar amount or
number of shares OR (if you are exchanging) the name of the fund you want to
exchange into and a dollar amount or number of shares. To exchange into an
account with a different registration (including a different name, address,
taxpayer identification number, or account type), you must provide Vanguard with
written instructions that include the guaranteed signatures of all current
owners of the fund from which you wish to redeem.

Vanguard Retirement Accounts:
For information on how to request distributions from:
- - Traditional IRAs and Roth IRAs--call Client Services.
- - SEP-IRAs, SIMPLE IRAs, 403(b)(7) custodial accounts, and Profit-Sharing and
Money Purchase Pension (Keogh) Plans--call Individual Retirement Plans at
1-800-662-2003.

Depending on your account registration type, additional documentation may be
required.

For clients of Vanguard's Institutional Division . . .

It is important that you call Vanguard before you redeem a large dollar amount.
It is our responsibility to consider the interests of all fund shareholders, and
so we reserve the right to delay delivery of your redemption proceeds--up to
seven days--if the amount may disrupt the Fund's operation or performance.

If you redeem more than $250,000 worth of fund shares within any 90-day
period, the fund reserves the right to pay part or all of the redemption
proceeds above $250,000 in-kind, i.e., in securities, rather than in cash. If
payment is made in-kind, you may incur brokerage commissions if you elect to
sell the securities for cash.
- --------------------------------------------------------------------------------

OPTIONS FOR REDEMPTION PROCEEDS

You may receive your redemption proceeds in one of three ways: check, exchange
to another Vanguard fund, or Fund Express redemption.

- --------------------------------------------------------------------------------
CHECK REDEMPTIONS
Normally, Vanguard will mail your check within two business days of a
redemption.
- --------------------------------------------------------------------------------

<PAGE>

EXCHANGE REDEMPTIONS
As described above, an exchange involves using the proceeds of your redemption
to purchase shares of another Vanguard fund.
- --------------------------------------------------------------------------------

FUND EXPRESS REDEMPTIONS
Vanguard will electronically transfer funds to your pre-linked checking or
savings account.

- --------------------------------------------------------------------------------

FOR OUR MUTUAL PROTECTION
For your best interests and ours, Vanguard applies these additional requirements
to redemptions:

REQUEST IN "GOOD ORDER"
All redemption requests must be received by Vanguard in "good order." This means
that your request must include:
- - The Fund name and account number.
- - The amount of the transaction (in dollars or shares).
- - Signatures of all owners exactly as registered on the account (for mail
requests).
- - Signature guarantees (if required).*
- - Any supporting legal documentation that may be required.
- - Any outstanding certificates representing shares to be redeemed.

*For instance, a signature guarantee must be provided by all registered account
shareholders when redemption proceeds are to be sent to a different person or
address. A signature guarantee may be obtained from most commercial and savings
banks, credit unions, trust companies, or member firms of a U.S. stock
exchange.

TRANSACTIONS ARE PROCESSED AT THE NEXT-DETERMINED SHARE PRICE AFTER VANGUARD HAS
RECEIVED ALL REQUIRED INFORMATION.
- --------------------------------------------------------------------------------
LIMITS ON ACCOUNT ACTIVITY
Because excessive account transactions can disrupt the management of a Fund and
increase the Fund's costs for all shareholders, Vanguard limits account activity
as follows:
- - You may make no more than TWO SUBSTANTIVE "ROUND TRIPS" THROUGH THE FUND
during any 12-month period.
- - Your round trips through the Fund must be at least 30 days apart.
- - The Fund may refuse a share purchase at any time, for any reason.
- - Vanguard may revoke an investor's telephone exchange privilege at any time,
for any reason.

A "round trip" is a redemption from the Fund followed by a purchase back into
the Fund. Also a "round trip" covers transactions accomplished by any
combination of methods, including transactions conducted by check, wire, or
exchange to/from another Vanguard fund. "Substantive" means a dollar amount that
Vanguard determines, in its sole discretion, could adversely affect the
management of the Fund.
- --------------------------------------------------------------------------------
RETURN YOUR SHARE CERTIFICATES
Any portion of your account represented by share certificates cannot be redeemed
until you return the certificates to Vanguard. Certificates must be returned
(unsigned), along with a letter requesting the sale or exchange you wish to
process, via certified mail to:

The Vanguard Group
455 Devon Park Drive
Wayne, PA 19087-1815

<PAGE>

- --------------------------------------------------------------------------------

ALL TRADES ARE FINAL
Vanguard will not cancel any transaction request (including any purchase or
redemption) that we believe to be authentic once the request has been initiated
and a confirmation number assigned.
- --------------------------------------------------------------------------------
UNCASHED CHECKS
Please cash your distribution or redemption checks promptly. Vanguard will not
pay interest on uncashed checks.

- --------------------------------------------------------------------------------

TRANSFERRING REGISTRATION

You can transfer the registration of your Fund shares to another owner by
completing a transfer form and sending it to Vanguard.

FUND AND ACCOUNT UPDATES

STATEMENTS AND REPORTS
We will send you account and tax statements to help you keep track of your Fund
account throughout the year as well as when you are preparing your income tax
returns.

In addition, you will receive financial reports about the Fund twice a
year. These comprehensive reports include an assessment of the Fund's
performance (and a comparison to its industry benchmark), an overview of the
financial markets, a report from the adviser, and the Fund's financial
statements which include a listing of the Fund's holdings.
To keep each Fund's costs as low as possible (so that you and other
shareholders can keep more of the Fund's investment earnings), Vanguard attempts
to eliminate duplicate mailings to the same address. When two or more Fund
shareholders have the same last name and address, we send just one Fund report
to that address--instead of mailing separate reports to each shareholder. If you
want us to send separate reports, notify our Client Services Department at
1-800-662-2739.

Each of the Vanguard International Stock Index Funds offers two separate classes
of shares: Investor and Institutional (except Developed Foreign Markets and
Total International Stock Index Funds, which offer only Investor Shares).
Investor Shares, which have an investment minimum of $3,000 ($1,000 for IRAs),
are offered by two separate prospectuses. This prospectus is intended for
participants in employer-sponsored retirement or savings plans. Another
version--for investors who would like to open a personal investment account--can
be obtained by calling Vanguard at 1-800-662-7447.

Note that the Funds' separate share classes have different expenses; as a
result, their investment performances will vary.

PRIMARY RISKS
THE FUND'S TOTAL RETURN, LIKE STOCK PRICES GENERALLY, WILL FLUCTUATE WITHIN A
WIDE RANGE, SO AN INVESTOR COULD LOSE MONEY OVER SHORT OR EVEN LONG PERIODS. The
Fund is also subject to:
- - Country risk, which is the chance that a country's economy will be hurt by
political troubles, financial problems, or natural disasters.
- - Regional risk, which is the chance that an entire region--namely the
Pacific region--will be hurt by political troubles, financial problems, or
natural disasters.
- - Currency risk, which is the chance that returns will be hurt by a rise in
the value of the U.S. dollar versus foreign currencies.
- - Investment style risk, which is the chance that returns from foreign stocks
will trail returns from other asset classes or the overall stock market.

MORE ON THE FUNDS

The following sections discuss other important features of Vanguard
International Stock Index Funds and Vanguard Institutional Developed Foreign
Markets Stock Index Fund, including indexing methods, fund characteristics,
additional risk information, costs and market-timing, fund turnover, and other
investment policies and risks.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
THE COSTS OF INVESTING

INDEXING METHODS
In seeking to track a particular index, a fund may use one of two indexing
methods to select the stocks it invests in.

<PAGE>

Some index funds hold each stock found in their target indexes in about the
same proportions as represented in the indexes themselves. For example, if 5% of
the S&P 500 Index were made up of the stock of a specific company, a fund
tracking that index would invest about 5% of its assets in that company.
Other index funds may use a different selection process. Because it would
be very expensive to buy all of the stocks held in certain indexes (the Select
Emerging Markets Free Index, for example, includes approximately 500 stocks),
funds tracking these larger indexes use a "sampling" technique. Using a
sophisticated computer program, these funds invest in stocks that will recreate
their target indexes in terms of industry, size, country, and other
characteristics. For instance, if 10% of the Select Emerging Markets Free Index
were made up of the stocks of a certain country, the Emerging Markets Stock
Index Fund would invest about 10% of its assets in stocks of the Index from that
country. The European, Pacific, and Emerging Markets Stock Index Funds each
employ this method of indexing. As a "fund of funds," the Institutional
Developed Foreign Markets Stock Index Fund allocates its assets among the
European Stock Index Fund Institutional Shares and Pacific Stock Index Fund
Institutional Shares.

- --------------------------------------------------------------------------------
PLAIN TALK ABOUT
"FUND OF FUNDS"

ADDITIONAL RISK INFORMATION
To track their target indexes as closely as possible, the European and Pacific
Stock Index Funds attempt to remain fully invested in foreign stocks included in
their particular indexes. The Emerging Markets Stock Index Fund normally invests
95% of its assets in foreign stocks, holding the remaining 5% in cash reserves
to meet daily redemption requests. The Institutional Developed Foreign Markets
Stock Index Fund normally holds100% of its assets in shares of its underlying
funds.

REGIONAL VERSUS BROAD INTERNATIONAL INVESTING

in the Japanese stock market may involve a higher degree of country risk than
that of more geographically diversified international funds.
EMERGING MARKETS STOCK INDEX FUND. As discussed above, emerging markets can
be substantially more volatile than both U.S and more developed foreign markets.
Therefore, the Emerging Markets Stock Index Fund may expose investors to a
higher degree of volatility than funds that invest in more developed markets.
INSTITUTIONAL DEVELOPED FOREIGN MARKETS STOCK INDEX FUND. As a fund of
funds, the Institutional Developed Foreign Markets Stock Index Fund intends to
invest all of its assets in shares of the European and Pacific Stock Index Funds
Institutional Shares; indirectly, its country risk will proportionately mirror
that of the European and Pacific Stock Index Funds.

SECURITY SELECTION
In seeking to track its target index, the European Stock Index, Pacific Stock
Index, and Emerging Markets Stock Index Funds each invest in a portfolio of
foreign stocks selected through statistical methods. The Institutional Developed
Foreign Markets Stock Index Fund simply invests in the Institutional Shares of
the European and Pacific Stock Index Funds.
EUROPEAN STOCK INDEX FUND. The Fund invests in a statistically selected
sample of approximately 550 common stocks included in the MSCI Europe Index,
which is made up of the stocks of companies located in 15 European countries.
Four countries--the United Kingdom, Germany, Switzerland, and France--dominate
the Index, with xx%, xx%, xx%, and xx%, respectively, as of December 31, 1999.
The other 11 countries, which include Austria, Belgium, Denmark, Finland,
Ireland, Italy, the Netherlands, Norway, Portugal, Spain, and Sweden, are much
less significant to the Index and, consequently, the Fund.
PACIFIC STOCK INDEX FUND. The Fund invests in a statistically selected
sample of the approximately 420 common stocks included in the MSCI Pacific Free
Index, which is comprised of the stocks of Pacific Basin companies. The Index is
dominated by the Japanese stock market, which represented xx% of the market
capitalization of the Index as of December 31, 1999. The other four countries
represented in the Index are Australia, Hong Kong, New Zealand, and Singapore.
EMERGING MARKETS STOCK INDEX FUND. The Fund invests in a statistically
selected sample of the approximately 500 common stocks included in the Select
Emerging Markets Free Index, which is made up of the stocks of companies located
in 13 emerging markets of Europe, Asia, Africa, and Latin America. Three
countries--Brazil, Mexico, and South Africa--represent a majority of the Index,
with xx%, xx%, and xx% of the market capitalization of the Index, respectively,
as of December 31, 1999. The other 10 countries include Argentina, the Czech
Republic, Greece, Hungary, Indonesia, Israel, Philippines, Poland, Thailand, and
Turkey. The developed countries of Hong Kong and Singapore are included in the
Index to broaden diversification and ensure adequate liquidity.
Although index funds, by their nature, tend to be tax-efficient investment
vehicles, the Funds are generally managed without regard to tax ramifications.

<PAGE>

COSTS AND MARKET-TIMING
Some investors try to profit from a strategy called market-timing--switching
money into investments when they expect prices to rise, and taking money out
when they expect prices to fall. As money is shifted in and out, a fund incurs
expenses for buying and selling securities. These costs are borne by all fund
shareholders, including the long-term investors who do not generate the costs.
Therefore, the Vanguard International and Vanguard Institutional Developed
Foreign Markets Stock Index Funds have adopted the following policies, among
others, designed to discourage short-term trading:
- - Each Fund reserves the right to reject any purchase request--including
exchanges from other Vanguard funds--that it regards as disruptive to the
efficient management of the Fund. A purchase request could be rejected
because of the timing of the investment or because of a history of
excessive trading by the investor.
- - Each Fund (except the Institutional Developed Foreign Markets Stock Index
Fund) charges a transaction fee on purchases. In addition, the Emerging
Markets Stock Index Fund charges a transaction fee on redemptions.
- - Telephone and online exchanges are not accepted for non-IRA accounts.
- - There is a limit on the number of times you can exchange into and out of a
Fund (see "Redeeming Shares" in the INVESTING WITH VANGUARD section).
- - Each Fund reserves the right to stop offering shares at any time.

THE VANGUARD FUNDS DO NOT PERMIT MARKET-TIMING. DO NOT INVEST IN THESE
FUNDS IF YOU ARE A MARKET-TIMER.

TURNOVER RATE
Although each Fund seeks to invest for the long term, the Funds retain the right
to sell securities regardless of how long the securities have been held.
Generally, a passively-managed fund sells securities only to respond to
redemption requests or to adjust the number of shares held to reflect a change
in the fund's target index. Because of this, the turnover rate for each Fund has
been extremely low. The Financial Highlights tables beginning on page xx show
historic turnover rates for each Fund.

investment companies with more than 100 funds holding assets worth more than
$xxx billion. All of the Vanguard funds share in the expenses associated with
business operations, such as personnel, office space, equipment, and
advertising.
Vanguard also provides marketing services to the funds. Although
shareholders do not pay sales commissions or 12b-1 distribution fees, each fund
pays its allocated share of The Vanguard Group's marketing costs.
Institutional Developed Foreign Markets Stock Index Fund will indirectly
bear a proportionate share of the expenses of the underlying funds in which it
invests. However, the Fund's direct expenses are expected to be very low or
zero. Institutional Developed Foreign Markets Stock Index Funds may operate
without incurring direct expenses because Vanguard will reimburse them for (i)
their contributions to the cost of operating the underlying funds in which they
invest, and (ii) savings in administrative and marketing costs that Vanguard
expects to derive from their operations.

INVESTMENT ADVISER
The Vanguard Group (Vanguard), P.O. Box 2600, Valley Forge, PA 19482, founded in
1974, serves as the Funds' adviser through its Core Management Group.
(Institutional Developed Foreign Markets Stock Index Fund receives advisory
services indirectly, by investing in the European and Pacific Stock Index Funds
Institutional Shares.) Vanguard manages the Funds on an at-cost basis, subject
to the control of the Trustees and officers of the Funds. The

<PAGE>

Funds began operations on May xx, 2000. Advisory fees for the first fiscal year
of the European, Pacific, and Emerging Markets Stock Index Funds Institutional
Shares is estimated at an effective annual rate of 0.xx%.
The Funds have authorized Vanguard to choose brokers or dealers to handle
the purchase and sale of securities for the Funds, and to get the best available
price and most favorable execution from these brokers or dealers with respect to
all transactions. The Funds may direct Vanguard to use a particular broker for
certain transactions in exchange for commission rebates or research services
provided to the Funds.

PLAIN TALK ABOUT
DISTRIBUTIONS

<PAGE>

- - Distributions declared in December--if paid to you by the end of
January--are taxable as if received in December.
- - Any dividends and short-term capital gains that you receive are taxable to
you as ordinary income for federal income tax purposes.
- - Any distributions of net long-term capital gains are taxable to you as
long-term capital gains for federal income tax purposes, no matter how long
you've owned shares in the Fund.
- - Capital gains distributions may vary considerably from year to year as a
result of the Funds' normal investment activities and cash flows.
- - A sale or exchange of Fund shares is a taxable event. This means that you
may have a capital gain to report as income, or a capital loss to report as
a deduction, when you complete your federal income tax return.
- - State and local income taxes may apply to any dividend or capital gains
distributions that you receive, as well as to your gains or losses from any
sale or exchange of Fund shares.
- - The European, Pacific, and Emerging Markets Stock Index Funds each may be
subject to foreign taxes or foreign tax withholding on dividends, interest,
and some capital gains that it receives on foreign securities. You may
qualify for an offsetting credit or deduction under U.S. tax laws for your
portion of a Fund's foreign tax obligations, provided that you meet certain
requirements. Because the Developed Foreign Markets Stock Index Fund
invests in foreign stocks indirectly through the European and Pacific Stock
Index Funds, its investors are not able to take advantage of foreign tax
credits or deductions. See your tax adviser or IRS publications for more
information.

"BUYING A DIVIDEND"

INVALID ADDRESSES. If a dividend or capital gains distribution check mailed to
your address of record is returned as undeliverable, Vanguard will automatically
reinvest all future distributions until you provide us with a valid mailing
address.

TAX CONSEQUENCES. This prospectus provides general tax information only. If you
are investing through a tax-deferred retirement account, such as an IRA, special
tax rules apply. Please consult your tax adviser for detailed information about
a fund's tax consequences for you.

SHARE PRICE
Each Fund's share price, called its net asset value, or NAV, is calculated each
business day after the close of regular trading on the New York Stock Exchange
(the NAV is not calculated on holidays or other days when the Exchange is
closed). Net asset value per share for the Institutional Developed Foreign
Markets Stock Index Fund is computed by adding up the total value of the Fund's
investments (i.e., shares of the underlying funds) and other assets, subtracting
any of its liabilities (debts), and then dividing by the number of Fund shares
outstanding:

TOTAL ASSETS - LIABILITIES
NET ASSET VALUE = --------------------------------
NUMBER OF SHARES OUTSTANDING

Net asset value per share for the European, Pacific, and Emerging Markets
Stock Index Funds is computed in a similar way, by dividing the net assets
attributed to each class by the number of Fund shares outstanding for that
class.
Knowing the daily net asset value is useful to you as a shareholder because
it indicates the current value of your investment. The Fund's NAV, multiplied by
the number of shares you own, gives you the dollar amount you would have
received had you sold all of your shares back to the Fund that day. Because
foreign securities markets may operate on days which are not business days in
the United States, the value of a Fund's holdings may change on days when
shareholders will not be able to purchase or redeem the Fund's shares.
A NOTE ON PRICING: A Fund's investments will be priced at their market
value when market quotations are readily available. When these quotations are
not readily available, investments will be priced at their fair value,
calculated according to procedures adopted by the Funds' Board of Trustees. A
Fund also may use fair value pricing if the value of a security held by the Fund
is materially affected by events occurring after the close of the primary
markets or exchanges on which such security is traded. In these situations,
prices used by the Fund to calculate its net asset value may differ from quoted
or published prices for the underlying securities.
Each Fund's share price can be found daily in the mutual fund listings of
most major newspapers under the heading "Vanguard Index Funds." Different
newspapers use different abbreviations for each Fund, but the most common are
XXXXXX, XXXXXX, XXXXXX, and XXXXXX for the European, Pacific, Emerging Markets,
and Institutional Developed Foreign Markets Stock Index Funds, respectively.

FINANCIAL HIGHLIGHTS
The following financial highlights tables are intended to help you understand
each Fund's financial performance for the past five years or since inception
(except for Institutional Developed Foreign Markets Stock Index Fund, which did
not start operations until May xx, 2000), and certain information reflects
financial results for a single Fund share. The total

<PAGE>

returns in each table represent the rate that an investor would have earned or
lost each year on an investment in the Fund (assuming reinvestment of all
dividends and capital gains distributions). This information has been derived
from the financial statements audited by PricewaterhouseCoopers LLP, independent
accountants, whose report--along with each Fund's financial statements--is
included in the Funds' most recent annual report to shareholders. You may have
the annual report sent to you without charge by contacting Vanguard. NOTE: This
prospectus offers the Funds' Institutional Shares not the Investor Shares.
Information for the Investor Shares is shown here because each of the Fund's
Institutional Shares are new. However, the two share classes are invested in the
same portfolio of securities and will have the same financial performance except
to the extent that their operating expenses differ.

Shareholders received $0.xx per share in the form of dividend and capital gains
distributions. A portion of each year's distributions may come from the prior
year's income or capital gains.

IMPORTANT NOTE: Once you have initiated a telephone transaction and a
confirmation number has been assigned, the transaction cannot be revoked. We
reserve the right to refuse any purchase request.
- --------------------------------------------------------------------------------
You can redeem (that is, sell or exchange) shares purchased by check at any
time. However, while your redemption request will be processed at the
next-determined net asset value after it is received, your redemption proceeds
will not be available until payment for your purchase is collected, which may
take up to ten calendar days.
- --------------------------------------------------------------------------------
A NOTE ON LARGE PURCHASES
It is important that you call Vanguard before you invest a large dollar amount.
It is our responsibility to consider the interests of all Fund shareholders, and
so we reserve the right to refuse any purchase that may disrupt the Fund's
operation or performance.
- --------------------------------------------------------------------------------

REDEEMING SHARES

This section describes how you can redeem--that is, sell or exchange--the Fund's
shares.

When Selling Shares:
- - Vanguard sends the redemption proceeds to you or a designated third party.*
- - You can sell all or part of your Fund shares at any time.

*May require a signature guarantee; see footnote on page 34.

When Exchanging Shares:
- - The redemption proceeds are used to purchase shares of a different Vanguard
fund.
- - You must meet the receiving fund's minimum investment requirements.
- - Vanguard reserves the right to revise or terminate the exchange privilege,
limit the amount of an exchange, or reject an exchange at any time, without
notice.
- - In order to exchange into an account with a different registration
(including a different name, address, or taxpayer identification number),
you must include the guaranteed signature of all current account owners on
your written instructions.

In both cases, your transaction will be based on the Fund's next-determined
share price, subject to any special rules discussed in this prospectus. Note
that the Funds do not permit telephone exchanges.
- --------------------------------------------------------------------------------
A NOTE ON REDEMPTION FEES
Emerging Markets Stock Index Fund imposes a 1% redemption fee on all share
redemptions. Currently, redemption fees do not apply to Fund shares held through
Vanguard's separate recordkeeping system for employee benefit plan accounts, due
to certain economies associated with these accounts. However, the Fund reserves
the right to impose redemption fees on its shares at any time if warranted by
the Fund's future costs of processing redemptions from these accounts.
- --------------------------------------------------------------------------------
NOTE: Once a redemption is initiated and a confirmation number given, the
transaction CANNOT be canceled.
- --------------------------------------------------------------------------------

HOW TO REQUEST A REDEMPTION
You can request a redemption from your Fund account in any one of three ways:
online, by telephone, or by mail.

<PAGE>

- --------------------------------------------------------------------------------
TELEPHONE REQUESTS [TELEPHONE ICON]
Call Vanguard Tele-Account 24 hours a day--or your assigned Service Associate
during business hours--to sell shares.

Vanguard Tele-Account
1-800-662-6273
- --------------------------------------------------------------------------------
SPECIAL INFORMATION: We will automatically establish the telephone redemption
option for your account, unless you instruct us otherwise in writing. While
telephone redemption is easy and convenient, this account feature involves a
risk of loss from unauthorized or fraudulent transactions. Vanguard will take
reasonable precautions to protect your account from fraud. You should do the
same by keeping your account information private and immediately reviewing any
account statements that we send to you. Make sure to contact Vanguard
immediately about any transaction you believe to be unauthorized.
- --------------------------------------------------------------------------------
We reserve the right to refuse a telephone redemption if the caller is unable to
provide:
- - The ten-digit account number.
- - The name and address exactly as registered on the account.
- - The primary Social Security or employer identification number as registered
on the account.
- - The Personal Identification Number (PIN), if applicable (for instance,
Tele-Account).

Please note that Vanguard will not be responsible for any account losses
due to telephone fraud, so long as we have taken reasonable steps to verify the
caller's identity. If you wish to remove the telephone redemption feature from
your account, please notify us in writing.
- --------------------------------------------------------------------------------
A NOTE ON UNUSUAL CIRCUMSTANCES
Vanguard reserves the right to revise or terminate the telephone redemption
privilege at any time, without notice. In addition, Vanguard can stop selling
shares or postpone payment at times when the New York Stock Exchange is closed
or under any emergency circumstances as determined by the U.S. Securities and
Exchange Commission. If you experience difficulty making a telephone redemption
during periods of drastic economic or market change, you can send us your
request by regular or express mail. Follow the instructions on selling or
exchanging shares by mail in this section.
- --------------------------------------------------------------------------------
MAIL REQUESTS [ENVELOPE ICON]
Send a letter of instruction signed by all registered account holders. Include
the fund name and account number and (if you are selling) a dollar amount or
number of shares OR (if you are exchanging) the name of the fund you want to
exchange into and a dollar amount or number of shares. To exchange into an
account with a different registration (including a different name, address,
taxpayer identification number, or account type), you must provide Vanguard with
written instructions that include the guaranteed signatures of all current
owners of the fund from which you wish to redeem.

<PAGE>

to delay delivery of your redemption proceeds--up to seven days--if the amount
may disrupt the Fund's operation or performance.
If you redeem more than $250,000 worth of fund shares within any 90-day
period, the fund reserves the right to pay part or all of the redemption
proceeds above $250,000 in-kind, i.e., in securities, rather than in cash. If
payment is made in-kind, you may incur brokerage commissions if you elect to
sell the securities for cash.
- --------------------------------------------------------------------------------

OPTIONS FOR REDEMPTION PROCEEDS
You may receive your redemption proceeds in one of three ways: check, exchange
to another Vanguard fund, or Fund Express redemption.
- --------------------------------------------------------------------------------
CHECK REDEMPTIONS
Normally, Vanguard will mail your check within two business days of a
redemption.
- --------------------------------------------------------------------------------
EXCHANGE REDEMPTIONS
As described above, an exchange involves using the proceeds of your redemption
to purchase shares of another Vanguard fund.
- --------------------------------------------------------------------------------
FUND EXPRESS REDEMPTIONS
Vanguard will electronically transfer funds to your pre-linked checking or
savings account.
- --------------------------------------------------------------------------------

FOR OUR MUTUAL PROTECTION
For your best interests and ours, Vanguard applies these additional requirements
to redemptions:

<PAGE>

A "round trip" is a redemption from the Fund followed by a purchase back into
the Fund. Also a "round trip" covers transactions accomplished by any
combination of methods, including transactions conducted by check, wire, or
exchange to/from another Vanguard fund. "Substantive" means a dollar amount that
Vanguard determines, in its sole discretion, could adversely affect the
management of the Fund.
- --------------------------------------------------------------------------------
ALL TRADES ARE FINAL
Vanguard will not cancel any transaction request (including any purchase or
redemption) that we believe to be authentic once the request has been initiated
and a confirmation number assigned.
- --------------------------------------------------------------------------------
UNCASHED CHECKS
Please cash your distribution or redemption checks promptly. Vanguard will not
pay interest on uncashed checks.
- --------------------------------------------------------------------------------

TRANSFERRING REGISTRATION

You can transfer the registration of your Fund shares to another owner by
completing a transfer form and sending it to Vanguard.

FUND AND ACCOUNT UPDATES

STATEMENTS AND REPORTS
We will send you account and tax statements to help you keep track of your Fund
account throughout the year as well as when you are preparing your income tax
returns.
In addition, you will receive financial reports about the Fund twice a
year. These comprehensive reports include an assessment of the Fund's
performance (and a comparison to its industry benchmark), an overview of the
financial markets, a report from the adviser, and the Fund's financial
statements which include a listing of the Fund's holdings.
To keep each Fund's costs as low as possible (so that you and other shareholders
can keep more of the Fund's investment earnings), Vanguard attempts to eliminate
duplicate mailings to the same address. When two or more Fund shareholders have
the same last name and address, we send just one Fund report to that
address--instead of mailing separate reports to each shareholder. If you want us
to send separate reports, notify our Institutional Division at 1-888-809-8102.
- --------------------------------------------------------------------------------
CONFIRMATION STATEMENT
Sent each time you buy, sell, or exchange shares; confirms the trade date and
the amount of your transaction.
- --------------------------------------------------------------------------------
PORTFOLIO SUMMARY [BOOK ICON]
Mailed quarterly for most accounts; shows the market value of your account at
the close of the statement period, as well as distributions, purchases, sales,
and exchanges for the current calendar year.
- --------------------------------------------------------------------------------
FUND FINANCIAL REPORTS
Mailed in February and August for these Funds.

TAX STATEMENTS

distributions, and proceeds from the sale of shares.

MANDATORY CONVERSION TO INVESTOR SHARES

Vanguard European, Pacific, and Emerging Markets Stock Index Funds each reserve
the right to convert any investor's Institutional Shares into Investor Shares of
the same Fund if the investor's account balance falls below $10 million. In
addition, Vanguard EAFE Institutional Stock Index Fund reserves the right to
redeem and investor's shares if the investor's account balance falls below $10
million. Any such conversion or redemption will be preceded by written notice to
the investor. No transaction fee will be imposed on share-class conversions.
