THE VANGUARD GROUP: LINKING TRADITION AND INNOVATION

     At Vanguard, we treasure our rich nautical heritage--even as we steer our
course toward the twenty-first century. Our Report cover reflects that blending
of tradition and innovation, of past, present, and future. The montage includes
a bronze medallion with a likeness of our namesake, HMS Vanguard (Lord Nelson's
flagship at The Battle of the Nile); a clock built circa 1816 in Scotland,
featuring a portrait of Nelson; and several views of our recently completed
campus, which is steeped in nautical imagery--from our buildings named after
Nelson's warships (Victory, Majestic, and Goliath are three shown), to our
artwork and ornamental compass rose.

FELLOW SHAREHOLDER,


     During the first half of Vanguard Municipal Bond Fund's fiscal year,
municipal bonds provided positive returns across the board. Interest rates
declined significantly from September through November, only to rebound through
the final three months of the period. Still, at the half-year's end on February
28, interest rates were slightly lower than they started.

     In this mildly favorable environment, the net asset values of all six of
the Fund's bond Portfolios increased, as reflected in the table that follows
this letter. (The net asset value of the Money Market Portfolio remained
constant at $1.00 per share, which is of course its goal, although this price is
neither guaranteed nor insured.) As should be expected, the price appreciation
for our Portfolios varied in proportion to their maturities, with the long-term
Portfolios providing larger increases. The table at the end of this letter also
presents each Portfolio's average credit quality, dividend distributions, and
current yield.

     During the six-month period, the Portfolios' total returns (capital change
plus reinvested dividends) ranged from +2.3% for the Short-Term Portfolio to
+5.0% for the Long-Term Portfolio. Price appreciation accounted for about
one-third of our total returns on average. Over time, price fluctuations tend to
even out, leaving interest income as the primary component of a bond fund's
long-term return. The Money Market Portfolio, which had no price appreciation,
provided a return of +1.7%.

     The table below presents the six-month total return of each Portfolio, as
well as the two components of this return: income and capital return.

     Six months ago in our 1996 Annual Report, we pointed out that relative
stability had returned to the bond market, ending its two-year sabbatical. In
the ensuing six months, the bond market remained mostly placid as moderate
economic growth continued and inflation appeared in check. The yield on
high-grade, long-term tax-exempt bonds dropped from 6.02% on August 31, 1996, to
5.61% by early December, before rising to 5.76% by February 28, 1997. Yields on
high-quality, short-term municipal securities traced a similar pattern, starting
the period at 3.65% and ending at 3.40%.

*Money market funds do not assure a stable value of $1.00 per share, and, unlike
 bank certificates of deposit, are not insured by the Federal Deposit Insurance
 Corporation.

     Of course, higher volatility in share prices comes with the higher yields
offered by longer-maturity bonds. Vanguard Municipal Bond Fund offers the
Short-Term and Limited-Term Portfolios for investors seeking yields higher than
those on money market securities at minimal risk of share-price fluctuations, as
well as longer-term Portfolios for investors who are willing to trade
intermittent--and sometimes wide--price swings for higher yield and increased
income durability.

     At the end of the semiannual period, the yield on long-term municipal bonds
was equal to 85% of the yield on long-term taxable bonds. This differential is
much wider than it was just 18 months ago, when talk of a "flat tax" appeared to
threaten the tax-exempt advantage of municipal bonds and drove the differential
to 92%. With that threat gone--at least for now--the yield differential between
taxable and tax-exempt bonds has settled into a more "normal" range, one that
continues to be exceptionally attractive to investors in marginal tax brackets
of 28% or higher.

     A constant throughout the history of Vanguard Municipal Bond Fund--a
history that for several of our Portfolios will soon encompass 20 years--has
been our relentless dedication to maintaining the highest standards of quality.
We hold the highest-quality bonds available and even buy some that are backed by
letters of credit from leading banks. Our Insured Long-Term Portfolio has an
average quality of Aaa, the highest of our longer-term portfolios. While our
emphasis on quality does not fully insulate our Portfolios from the credit woes
of any individual security, it goes a long way toward protecting against the
ever-present risk of defaults.

     Our effort to maintain the high quality of our holdings--part of the
foundation of the Fund's investment philosophy--is, of course, aided by our low
expenses. Each Portfolio maintains an expense ratio (expenses as a percentage of
average net assets) of about 0.20%. Expense ratios for our competitors range
from an average of 0.59% for short-term funds to more than 1.10% for long-term
and high-yield funds, for an overall average of 0.95%. Thus, our low expenses
provide annual savings that average 0.75%, or $7.50 per $1,000 of assets, for
Vanguard shareholders. This built-in yield advantage over our competitors puts
our portfolio managers in the enviable position of being able to ignore the
temptation to reach for higher yields through riskier bonds. The net result:
Our overall credit quality is peerless in the industry.

     Though the semiannual period has been relatively calm for Vanguard
Municipal Bond Fund, tranquility is hardly the norm for the bond market.
Interest rates and financial markets often fluctuate unpredictably, driving bond
prices lower or vaulting them higher. However, we remind investors that
maintaining a long-term investment strategy and a diversified portfolio that
includes bond funds along with stock and money market funds will help dampen the
short-term volatility that is always part of investing.

     We look forward to reporting to you on the full year's results six months
from now in our 1997 annual report.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED FEBRUARY 28, 1997

U.S. EQUITY MARKETS

The favorable confluence of steady economic growth, low inflation, and rising
corporate earnings made for a very rewarding six months. Stocks, as measured by
the Standard & Poor's 500 Composite Stock Price Index, gained 22.5%.

     Much attention has been focused on the market's rise, irrational or
otherwise. In fact, investors' returns have varied widely, depending on their
definition of the "market." Clearly, the best rewards have been in larger
companies, such as those that dominate the S&P 500 Index. In fact, even within
the Index, it was the largest companies that prevailed: The 50 biggest (which
account for roughly half the Index's market value) gained 27.0% over the last
six months, 4.5 percentage points more than the overall Index. Looking at the
S&P 500 Index's performance by sector, financial stocks were strongest, with a
33.5% gain, followed closely by technology issues (up 32.6% as a group). Despite
the economy's good tone, several of the more economically sensitive sectors
failed to keep up with the market. Auto stocks gained 12.5%, while other stocks
closely related to consumer spending, such as retailers and restaurants, were up
10.1%.

     Those who chose to invest outside the very largest companies earned
decidedly different returns. The 8.8% return of the Russell 2000 Index of small
stocks, for example, lagged the S&P 500 Index by more than half. Here there was
some symmetry with the other index, as small financial issues were the best
performers (up 21.3%), but small technology issues fell far short of their S&P
counterparts, rising a modest 3.9%. This sector includes many companies
competing for share in the crowded networking and Internet markets.

U.S. FIXED-INCOME MARKETS

Bond investors were challenged over the period. The stock market's double-digit
returns cast a long shadow, while bond prices reacted daily--and even hourly in
some cases--to economic reports. Perversely, news of an expanding economy would
push bond yields up (and bond prices down) as the market translated good
economic news into fear of higher inflation. Throughout the period, however,
inflation, as measured by the Consumer Price Index (CPI), remained remarkably
benign. The CPI registered an increase of 3.0% for



                                       4
<PAGE>   7

the 12 months through February. As the month closed, however, a number of strong
economic reports led to an increasing conviction among bond investors that the
Federal Reserve would have to increase rates, albeit modestly.

     In general, interest rates fell for the period, spurred by a strong
post-election rally. On February 28, the 30-year U.S. Treasury yield was 6.80%,
noticeably lower than the 7.12% level on August 31. Although the bond market's
primary focus was on inflation, with yields moving up or down accordingly, the
shrinking of the yield difference between Treasury issues and corporate bonds is
another development worth mentioning. The strong corporate earnings of recent
years, with the resulting lower risk of default, have decreased the premium
typically demanded by investors for higher credit risk. Significantly, the yield
difference between the 10-year Treasury note, backed by the full faith and
credit of the U.S. government, and the lowest-credit-quality bonds tracked by
Merrill Lynch has narrowed from 3.5 percentage points one year ago to 2.8
percentage points at the end of February. While not as dramatic for all
relationships, the shrinking yield premiums gave corporate bonds a performance
edge over Treasuries of comparable maturities.

     Mortgage-backed issues and municipals were two other relative bright spots
over the past year. The generally stable-to-rising interest-rate environment
benefited mortgages as the threat of refinancings receded. Finally, municipal
bonds outpaced their U.S. Treasury counterparts as demand outstripped supply for
much of the year.

INTERNATIONAL EQUITY MARKETS

In general, foreign markets enjoyed a strong six months. For U.S. investors,
however, some of those returns were trimmed by a very strong dollar. The Morgan
Stanley Capital International-Europe, Australasia, Far East Index showed an
11.2% return. When that number is adjusted for U.S. investors, however, the
return drops to 2.4%.

     Regionally, there was a striking disparity between the European and Pacific
markets. In aggregate, Europe's markets provided U.S. investors with a gain of
13.8%, while the Pacific markets declined -10.1%. The poor returns in the
Pacific region reflected ongoing concern about the health of the Japanese
economy. Growth in Japan has remained modest at best for several years despite
government efforts to stimulate the economy through public works programs and
tax incentives. The country is also wrestling with massive changes to its
financial infrastructure. In Europe, the picture was dramatically different,
with the region benefiting from a variety of factors. Among the most important
were (1) ongoing efforts to lower government deficits consistent with the
Maastricht Treaty guidelines; (2) improving economic growth; and (3) a greater
commitment by corporate executives to increasing "shareholder value."

REPORT FROM THE ADVISER

STEADY AS SHE GOES . . .

The six months ended February 28, the first half of the fiscal year for Vanguard
Municipal Bond Fund, witnessed a very mild albeit favorable downward trend in
interest rates on municipal securities. During the period, long-, intermediate-,
and short-term rates dropped by 0.20% to 0.30% (20 to 30 basis points). That's
good news. After the angst of the previous fiscal year, any restoration of
stability and normalcy should be welcomed with relief, if not enthusiasm.

     Economic growth has been positive over this period without any of the
excesses that would lead investors to believe inflation (or the Federal Reserve
Board's reaction to inflation) was getting out of hand. These periods of bond
market tranquility are as desirable as they are unusual. It's a pity such a
benign environment for bonds has been eclipsed by the feeding frenzy in the
stock market.

     The recent pyrotechnics in equity market returns have overshadowed the
staid world of bond investing. The 5.1% six-month return of a garden-variety
municipal bond pales alongside the adrenaline-pumping 22.5% return posted over
the same period by the Standard & Poor's 500 Composite Stock Price Index. Small
wonder, therefore, that new cash and new investors are pouring into the hot
stock market in record numbers. We think that's unfortunate--an opinion that's
not just "sour grapes."

     The burgeoning (arguably, excessive) cash flows into equities at the
expense of bond funds seemingly trivializes two of the most important attributes
of investing in fixed-income assets. First, investing in bonds makes sense
because bond returns are poorly correlated with equity returns. Bond prices and
stock prices often move in opposite directions. Consequently, a blend of stocks
and bonds significantly reduces overall portfolio risk.

     The seven Portfolios of Vanguard Municipal Bond Fund offer a virtually
unrivaled means to "mix and match" combinations of tax-exempt Portfolios with
other asset classes to create varied baskets of securities that satisfy
investors' tolerances for volatility. Each Portfolio is extremely
cost-effective, with expenses equal to approximately 0.20% of assets per year
(roughly one-fifth to one-third of the industry average). Also, each Portfolio
is invested under guidelines that produce a relatively consistent mix of
market-risk exposure and dividend durability.

     The table on the next page presents our estimate of the volatility of each
Portfolio's net asset value (NAV) compared to that of our benchmark Long-Term
Portfolio. It also shows how much the NAV might fluctuate in response to changes
in the general level of interest rates. For example, a 1.0% rise in interest
rates will lower the NAV of the Limited-Term Portfolio by about -2.8%, only
one-third the decline that would occur in the NAV of our Long-Term Portfolio.
The table shows that the Intermediate-Term Portfolio is effectively 64% as
sensitive as the Long-Term Portfolio to a change in interest rates. Over the
long haul, most fluctuations in interest

INVESTMENT PHILOSOPHY

Each Portfolio holds a diversified group of municipal bonds designed to produce
a high level of current, tax-exempt income consistent with each Portfolio's
maturity and quality mandates. In managing the Fund, Vanguard Fixed Income Group
follows a disciplined investment policy, meeting well-defined standards for
credit quality and keeping each Portfolio within its stated maturity range,
while seeking to exceed, with reasonable consistency over the long term, average
returns achieved by comparable funds.


                                       6

rates tend to cancel themselves out, and the investor is left with the second
compelling attribute of municipal bonds as an asset class: tax-exempt
compounding of interest income.

     Municipal notes and bonds today provide attractive levels of interest
income compared to the dividend yields of most common stocks and particularly
compared to historical inflation rates. Over the long run, interest income and
the compounding of reinvested interest income represent the vast majority of a
bond's cumulative return. As such, bond funds represent the "Clydesdales" of an
investment portfolio, producing steady and attractive (if less than
awe-inspiring) returns over extended periods. Given the supercharged equity
markets of the 1990s, it's unfortunately all too easy to forget the virtues of a
consistent income-producer. It is only a matter of "when"--not "if"--these bond
virtues will be somewhat painfully rediscovered.

ENDURING THEMES

The Portfolios of Vanguard Municipal Bond Fund differ from competing mutual
funds in several important respects. Foremost is the gaping differential in
expenses. Our low costs permit us to maintain generally higher credit quality
than competitors do, and (in most of our Portfolios) to avoid buying bonds whose
interest income might subject shareholders to the federal Alternative Minimum
Tax (AMT). In essence, the low-cost advantage enables us to pursue a higher
level of quality and a "purer" degree of tax avoidance without producing a net
portfolio yield lower than our competitors'. Indeed, Vanguard Municipal Bond
Fund Portfolios generally carry higher distribution yields than competing funds.
There is no free lunch; we give up some yield to buy higher-quality bonds and to
avoid bonds whose interest is subject to AMT. However, the "cost" of these
desirable features only partially offsets the expense advantage enjoyed by the
Portfolios.

     The expense advantage also permits Portfolio management to be more
single-minded in its pursuit of total return, that combination of both principal
preservation and income generation. Frequently, portfolio managers are presented
with investment opportunities that entail making an initial sacrifice in yield
for the sake of potentially reaping outsized future returns when market
conditions revert to normalcy. Vanguard's more-than-competitive net yields
permit a fuller exploitation of these opportunities, to the eventual benefit of
principal and interest income components alike.

     Over time, the collective efforts of professional management and lower
expenses will translate into superior relative Portfolio returns. With
additional luck and pluck, the forgotten asset class will be remembered for its
manifest virtues.

PERFORMANCE SUMMARIES

All of the data on this page represent past performance, which cannot be used to
predict future returns that may be achieved by the Portfolios. Note, too, that
returns can fluctuate widely. An investment in a money market fund is neither
insured nor guaranteed by the U.S. government, and there is no assurance that
the fund will be able to maintain a stable net asset value of $1.00 per share.

FINANCIAL STATEMENTS
FEBRUARY 28, 1997 (UNAUDITED)

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Municipal Bond Fund Portfolios, are included as an insert
to this report.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each Portfolio during the reporting
period, and details the operating expenses charged to the Portfolio. These
expenses directly reduce the amount of investment income available to pay to
shareholders as tax-exempt income dividends. This Statement also shows any Net
Gains (Losses) realized on the sale of investments, and the increase or decrease
in the Unrealized Appreciation (Depreciation) on investments during the period.
If the Portfolio invested in futures contracts during the period, the results of
these investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each Portfolio's total net assets changed during the
two most recent reporting periods. The Operations section summarizes
information that is detailed in the Statement of Operations. Because the
Portfolio distributes its income to shareholders each day, the amounts of
Distributions-Net Investment Income generally equal the net income earned as
shown under the Operations section. The amounts of Distributions-Realized
Capital Gain may not match the capital gains shown in the Operations section,
because distributions are determined on a tax basis and may be made in a period
different from the one in which the gains were realized on the financial
statements. The Capital Share Transactions section shows the amount
shareholders invested in the Portfolio, either by purchasing shares or by
reinvesting distributions, and the amounts redeemed. The corresponding numbers
of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each Portfolio's investment results and distributions to
shareholders on a per-share basis. It also presents the Portfolio's Total
Return and shows net investment income and expenses as percentages of average
net assets. These data will help you assess: the variability of the Portfolio's
net income and total returns from year to year; the relative contributions of
net income and capital gains to the Portfolio's total return; how much it costs
to operate the Portfolio; and the extent to which the Portfolio tends to
distribute capital gains.

    The table also shows the Portfolio Turnover Rate, a measure of trading
activity. A turnover rate of 100% means that the average security is held in
the Portfolio for one year. Money market portfolios do not show a turnover rate
because securities with less than one year to maturity are excluded from the
calculation of turnover rates.

NOTES TO FINANCIAL STATEMENTS

Vanguard Municipal Bond Fund is registered under the Investment Company Act of
1940 as a diversified open-end investment company, or mutual fund, and
comprises the Money Market, Short-Term, Limited-Term, Intermediate-Term,
Insured Long-Term, Long-Term, and High-Yield Portfolios. Each Portfolio invests
in debt instruments of many municipal issuers; the issuers' abilities to meet
their obligations may be affected by economic and political developments in a
specific state or region.

A.  The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The Fund consistently follows such
policies in preparing its financial statements.

    1. SECURITY VALUATION: Money Market Portfolio: Investment securities are
valued at amortized cost, which approximates market value. Other Portfolios:
Municipal bonds are valued using primarily the latest bid prices or, if bid
prices are not available, using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by an independent pricing service.

    2. FEDERAL INCOME TAXES: Each Portfolio intends to continue to qualify as a
regulated investment company and distribute all of its income. Accordingly, no
provision for federal income taxes is required in the financial statements.

    3. FUTURES CONTRACTS: Each Portfolio, except the Money Market Portfolio,
may use Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note
futures contracts to a limited extent, with the objectives of enhancing
returns, managing interest-rate risk, maintaining liquidity, diversifying
credit risk and minimizing transaction costs. The Portfolios may purchase or
sell futures contracts instead of bonds to take advantage of pricing
differentials between the futures contracts and the underlying bonds. The
Portfolios may also seek to take advantage of price differences among bond
market sectors by simultaneously buying futures (or bonds) of one market sector
and selling futures (or bonds) of another sector. Futures contracts may also be
used to simulate a fully invested position in the underlying bonds while
maintaining a cash balance for liquidity. The primary risks associated with the
use of futures contracts are imperfect correlation between changes in market
values of bonds held by the Portfolios and the prices of futures contracts, and
the possibility of an illiquid market.

    Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in
the financial statements. Fluctuations in the values of futures contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized futures gains
(losses).

    4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

    5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums
and original issue discounts are amortized and accreted, respectively, to
interest income over the lives of the respective securities.

B.  The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the Fund under methods approved by the board of
directors. At February 28, 1997, the Fund had contributed capital aggregating
$1,652,000 to Vanguard (included in Other Assets), representing 8.3% of
Vanguard's capitalization. The Fund's directors and officers are also directors
and officers of Vanguard.

C.  The Fund's investment adviser may direct new issue portfolio purchases,
subject to obtaining the best price and execution, to underwriters who have
agreed to rebate or credit to the Fund part of the underwriting fees generated.
Such rebates or credits are used solely to reduce the Fund's





                                       22

administrative expenses. The Fund's custodian bank has also agreed to reduce
its fees when the Fund maintains cash on deposit in the non-interest-bearing
custody account. For the six months ended February 28, 1997, directed brokerage
and custodian fee offset arrangements reduced expenses by:

VANGUARD MUNICIPAL BOND FUND
FINANCIAL STATEMENTS
FEBRUARY 28, 1997 (unaudited)

The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appears in the accompanying Report.

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each Portfolio's municipal bond
holdings by state, including each security's market value on the last day of
the reporting period and information on credit enhancements such as insurance
or letters of credit. Other assets are added to, and liabilities are subtracted
from, the value of Total Municipal Bonds to calculate the Portfolio's Net
Assets.  Finally, Net Assets are divided by the outstanding shares of the
Portfolio to arrive at its share price, or Net Asset Value (NAV) Per Share.

     At the end of the Statement of Net Assets of each Portfolio, you will find
a table displaying the composition of the Portfolio's net assets on both a
dollar and per-share basis. Undistributed Net Investment Income is usually zero
because the Portfolio distributes its net income to shareholders as a dividend
each day. Any realized gains must be distributed annually, so the bulk of net
assets consists of Paid in Capital (money invested by shareholders). The
balance shown for Accumulated Net Realized Gains usually approximates the
amount available to distribute to shareholders as taxable capital gains as of
the statement date, but may differ because certain investments or transactions
may be treated differently for financial statement and tax purposes. Any
Accumulated Net Realized Losses, and any cumulative excess of distributions
over net realized gains, will appear as negative balances. Unrealized
Appreciation (Depreciation) is the difference between the value of the
Portfolio's investments and their cost, and reflects the gains (losses) that
would be realized if the Portfolio were to sell all of its investments at their
statement-date values.
