OUR CREW MAKES THE DIFFERENCE

Throughout its history, The Vanguard Group has received considerable attention
as the low-cost provider of mutual funds. While such accolades are gratifying,
we are most proud, not of our low operating expenses or the billions of dollars
we manage, but of our sterling reputation created by the Vanguard crew.

     We recognize that it is our crew members--some 6,000 highly motivated men
and women--who form the cornerstone of our operations. As with any cornerstone,
we could not survive long--let alone prosper--without it. That's why we chose
this fiscal year's annual report to celebrate the spirit, enthusiasm, and
achievements of our crew. (We call those who work at Vanguard crew members, not
employees, because they operate as a team to accomplish our mission of serving
you, our clients.)

     But while we prize the collective contributions of our crew, we also take
time to recognize the importance of the individual.  Each calendar quarter, we
present our Award For Excellence to a handful of crew members who have
demonstrated particular excellence in the performance of their jobs and who
embody "The Vanguard Spirit." Our report cover shows only a few of the more
than 300 crew members who have received this distinction since 1984.

     They, along with the rest of our valiant crew, look forward to serving you
in the years ahead.

FELLOW SHAREHOLDER,

The somewhat unlikely combination of robust economic growth and tame inflation
afforded a healthy climate for fixed-income investments during Vanguard
Municipal Bond Fund's 1997 fiscal year. Interest rates declined on balance for
all but municipal money market securities during the twelve months ended August
31, providing a boost for bonds, particularly those with the longest
maturities.

     The Portfolios of Vanguard Municipal Bond Fund provided a strong showing
across the board. Returns ranged from +3.5% for our Money Market Portfolio to
+9.5% for our Long-Term and High-Yield Portfolios. These are solid returns for
fixed-income funds--particularly since 100% of the income return is free from
federal income taxes. The table at right presents the total return (capital
change plus reinvested dividends) for each Portfolio for the twelve months,
broken down into its capital and income components. It also shows each
Portfolio's yield as of August 31.

     Per-share figures for each Portfolio, including net asset values, income
dividends, and any distributions from net realized capital gains, are presented
in the table following this letter.

FISCAL 1997 PERFORMANCE OVERVIEW

During the twelve months ended August 31, economic growth continued--taking the
nation's unemployment rate to its lowest point in more than two decades--and
inflation remained on its best behavior. This idyllic confluence pushed stocks
to new heights and provided a solid foundation for bonds.

     Though market participants worried that the strong economy and low
unemployment would drive wages and inflation higher, no such increase in the
cost of goods and services materialized. (The Consumer Price Index rose just
2.2% during the fiscal year.) Interest rates reacted accordingly. On balance
during the year, the yield on the benchmark 30-year U.S. Treasury bond declined
by one-half percentage point, to 6.61%. In the municipal market, the yield on
high-grade, long-term municipal bonds dropped on balance to 5.55% from 6.02%.
Yields on high-quality, short-term municipal securities finished the year at
3.65%, exactly where they started.

     At the end of the fiscal year, the 5.55% yield on 20-year tax-exempt bonds
was roughly equivalent to the level a year ago and equal to 83% of the yield on
20-year (taxable) U.S. Treasury bonds. For investors in the maximum marginal
tax bracket of 39.6%, the taxable equivalent yield is 9.19%, which continues to
make municipal bonds highly attractive.

     The returns provided by the bond market, while quite strong in absolute
terms, were meager in comparison with those of the U.S. stock market. Stocks
surged again in

                                       1

the twelve months ended August 31, with the Standard & Poor's 500 Composite
Stock Price Index rocketing to a +40.6% gain. The rosy economic scenario
heightened the already-ebullient mood of investors, with the result that stock
prices rose even faster than the underlying earnings. By the close of the
fiscal year, the prices of the S&P 500 stocks were at or near historic highs in
relation to earnings, dividends, and book values.

     Predictably, the decline in interest rates affected the net asset values
of our tightly constructed Portfolios in proportion to their maturities. Our
Long-Term Portfolio--the most sensitive to changes in interest
rates--experienced the largest share-price increase, while our
Intermediate-Term Portfolio--half as sensitive to interest rates--also
benefited from the interest rate decline.  Our Short-Term and Limited-Term
Portfolios received only a slight nudge from share-price appreciation, leaving
dividends from tax-exempt interest as the chief source of their total returns.
Our Money Market Portfolio maintained its share price of $1.00, as is expected
though not guaranteed.

     We expect to make year-end distributions of realized capital gains to
shareholders of four of our Portfolios. Based on estimates as of August 31, we
expect the distributions to total $0.05 per share for our Intermediate-Term
Portfolio; $0.08 per share for our Insured Long-Term Portfolio; $0.06 for our
Long-Term Portfolio; and $0.05 for our High-Yield Portfolio.

     Compared with those of our peers, Vanguard Municipal Bond Fund's
performance was solid, as all but two of our Portfolios outpaced the average
competing funds over the twelve months. This fine accomplishment burnishes our
longer-term competitive record.  This is the ninth annual report in which we
have compared returns of the seven Portfolios of Vanguard Municipal Bond Fund
with the returns of their peer fund groups. Out of these 63 side-by-side
comparisons, our Portfolios prevailed in 56, with 2 ties and only 5 "losses."
The past year's results are shown in the table.

</TABLE>
*Adjusted for maturity differences.

     The slight shortfall of our High-Yield Portfolio is explained in part by
the distress of industrial revenue bonds issued to finance so-called de-inking
plants that process recycled paper. We were hurt by holding two such bonds,
amounting to about 1.7% of the Portfolio. Though our High-Yield Portfolio
generally holds a bigger share of higher-quality issues than our peers--a
policy that has served our shareholders well over the long term--this episode
illustrates that we are not immune to the ever-present risks of investing in
higher-yielding, and thus riskier, bonds.

     Over time, the bond market has demonstrated both the negative and positive
effects of interest rate changes. During Vanguard Municipal Bond Fund's past
four fiscal years, rising interest rates have twice hampered bond returns,
while falling interest rates have twice augmented them. This brief history
provides a valuable lesson: Though bond prices can be volatile over short
periods, these fluctuations often cancel each other out over longer periods. As
a result, the long-term returns on bonds are almost always determined by income
returns rather than capital returns. In short, yield matters.

LONG-TERM PERFORMANCE OVERVIEW

Viewed through the wide-angle lens of our longer-term performance--a much more
useful measure than a twelve-month snapshot--our results are even more
impressive. The Performance Summaries on pages 9 through 15 present the
long-term results for each of our Portfolios, including yearly breakdowns of
the income and capital returns earned by each, as well as cumulative returns
for the period. The table below summarizes the long-term total returns of each
Portfolio relative to the average return of comparable fixed-income mutual
funds for the ten years ended August 31. It also shows how a $10,000 investment
in each fund would have grown over the decade.

     As the table shows, each of our Portfolios has outperformed its peer group
during these longer periods. Over the years, our margin of superiority, which
we call the "Vanguard advantage," can add up to considerable sums. Our annual
average margins of superiority range from 0.2 percentage point to 1.3
percentage points, equating over a decade to amounts from $371 to $2,505 (about
4% to 25% of the initial investment) in extra return compared with our peers.

**Adjusted for maturity differences.

     Costs matter for all mutual funds, but particularly for bond funds, where
expenses account for a large share of the difference in the performance of
funds with similar quality and maturity. On that score, as we hope you are
aware, we are without peer. The expense ratios of Vanguard Municipal Bond
Fund's Portfolios averaged about 0.20% of net assets in fiscal 1997 versus the
0.95% expense ratio of the average municipal bond fund--a difference of about
0.75%, or about $7.50 for each $1,000 in assets. The cost advantage flows to
our shareholders, since expenses directly reduce the income passed through to
bond fund investors. Thus, just as yield matters, so cost matters.

     Much of the credit for our long-term success also goes to Vanguard Fixed
Income Group, which manages our Portfolios with outstanding expertise and
professionalism within our clearly defined maturity and credit-quality
standards.

     The Performance Summaries that follow compare the returns of our six
non-money market Portfolios with unmanaged index benchmarks. Over the past ten
years, all six Portfolios outpaced their competitors, and five of them (our
Short-Term Portfolio was the exception) also outpaced their respective indexes.
This is a noteworthy accomplishment, since the indexes exist only on paper and
are not burdened by the operating, advisory, and securities-transaction costs
that, in the real world, all mutual funds bear to one degree or another.

     We caution that the absolute returns shown in the table should not be
considered a promise of what's to come in the municipal bond market. The past
decade has been a generous one for bonds, as interest rates have receded from
levels much higher than those





                                       3
<PAGE>   6
prevailing today. Therefore, there is little chance that future returns will be
as high as those of the past decade.

     We offer no such warning about our relative performance. We fully expect
that our Portfolios' returns will continue to more than measure up to those of
our peers, given our confidence that Vanguard's low costs and sound management
are enduring advantages.

IN SUMMARY

The rewards of the financial markets, particularly those of the U.S. stock
market, have been abundantly clear over the past three years. Though the
inherent risks of investing may not seem as obvious, we assure you that they
exist. We need look back only a few years for evidence of the wide and
unpredictable swings that are very much a part of bond investing. With bond
yields now near their lows for the past decade, we have taken a conservative
stance, with average maturities somewhat below our norms.

     The prudent approach is to bear in mind both risk and reward in
constructing a balanced portfolio of stock funds, bond funds, and reserves in
proportions suitable to your investment goals, time horizon, and tolerance for
market downturns. Then, as we have advised many times in the past, stay the
course toward your investment objective.

  NOTE: Vanguard Municipal Bond Fund's fiscal year-end is being changed from
  August 31 to October 31. The change will have no effect on the Fund's
  investment objective or policies. It is designed to enable the Portfolio
  managers to better match the realization of capital gains with the timing of
  distributions to the Fund's tax-sensitive shareholders.

       In December, shareholders will receive a report similar to this one, but
  covering the period from August 31, 1997, through October 31, 1997. After
  that, shareholders will receive a semiannual report each June, covering the
  six months through April 30, and an annual report each December that covers
  the twelve months through October 31.

THE MARKETS IN PERSPECTIVE
Year Ended August 31, 1997

U.S. EQUITY MARKETS

To say that investors in financial assets fared well over the fiscal year ended
August 31, 1997, is to be guilty of understatement.  Virtually across the
board, returns in the equity and bond markets ranged from quite strong to
exceptional, relative to historical averages. These results can be attributed
to three factors: continued solid economic growth; harnessed inflation,
remaining at levels not experienced since the 1960s; and growth in corporate
profits that was not only impressive but exceeded expectations. The most
surprising aspect of this remarkable period is that the rate of inflation
actually continued to decline despite robust growth and a very low level of
unemployment. According to traditional economic theory, inflation should have
accelerated rather than slowed at this point in the economic cycle. The most
widely accepted explanation for this paradox involves ongoing and substantial
productivity gains that are not apparent from the productivity measures in use
today. Reports indicate that even the Federal Reserve Board is otherwise at a
loss to explain the current "economic nirvana."

     The performance of large-capitalization U.S. common stocks was nothing
short of spectacular during the past year, as illustrated by the 40.6% gain
generated by the Standard & Poor's 500 Composite Stock Price Index. This
advance ranks among the top 5% for all 12-month periods in the last 20 years.
The best-performing sectors were technology and financial services, with
increases of 80.5% and 51.9%, respectively. The surge in technology reflects
the exceptional strength in corporate spending on this industry's products,
particularly desktop computers, networking equipment, and software. By
contrast, utility stocks could be considered laggards despite their overall
return of 18.8%.

  The performance of small-company stocks, while it failed to match the
outsized advance of the S&P 500 Index, cannot be characterized as weak during
this period--the Russell 2000 Index gained 29.0%. The difference in return
between large and small companies can be attributed, at least in part, to the
superior earnings growth achieved by larger companies during the past 24
months. In addition, large companies generated better-than-expected earnings
60% of the time over the past year, compared to only 40% for small firms.
Within sectors, the most dramatic difference between large and small companies
appeared in technology issues.  In the Russell 2000 Index, technology stocks
advanced "only" 32.9% in aggregate, nearly 50 percentage points less than their
large-company counterparts.

U.S. FIXED-INCOME MARKETS

The fixed-income markets also rewarded investors over the past year, as rates
fell across the yield curve. For example, the rates on 1-, 5-, 10-, and 30-year
U.S. Treasury issues fell 0.33%, 0.51%, 0.60%, and 0.51%, respectively, from
August 31, 1996, to August 31, 1997. These declines reflect the continued good
news regarding inflation and the relative dormancy of the Federal Reserve. The
benefit of the drop in rates can be seen in the 10.0% return of the Lehman
Brothers Aggregate Bond Index, the broadest measure of investment-grade issues.
Investors in lower-quality securities fared even better, as illustrated by the
15.2% gain of the Lehman High Yield Bond Index. The strength of the economy
combined with the lack of inflationary pressure produced an ideal environment
for junk bonds.

INTERNATIONAL EQUITY MARKETS

Investments in non-U.S. common stocks did not match the gains in domestic
equities, with the Morgan Stanley Capital International Europe, Australasia,
Far East Index advancing 9.4% in dollars. This Index's relatively modest
performance masks the fact that the European markets were very strong during
the past year, gaining 42.2% in local currency terms and 26.2% in dollars,
while many of the Pacific Basin markets were weak, down 0.7% in local currency
and 9.8% in dollars. The Japanese market declined 11.4% in dollars and 1.9% in
yen terms, despite signs of a strengthening economy. Smaller Asian markets,
such as Malaysia (losing 28.9% in local terms and 39.2% in dollars), suffered
from a variety of challenges, including overvalued currencies, rising interest
rates, and poor earnings.

REPORT FROM THE ADVISER

Interest rates were lower on August 31, the end of Vanguard Municipal Bond
Fund's fiscal year 1997, than at the start of the period.  Intermediate- and
long-term rates declined by amounts ranging from about 0.20% to 0.45% (20 to 45
basis points) over the course of the year, with most of the reduction occurring
in the first six months of the period. However, the second half of the fiscal
year was hardly tranquil, as some very significant events moved the bond
markets. First, in March the Federal Reserve Board chose to strike
"preemptively" against inflation by raising short-term interest rates. Second,
Republicans and Democrats were able to reach a compromise on the federal
budget. Third, the economy continued to expand at a rate above 3%. Finally, the
stock market was able to sustain its historic run, reaching record highs in
August.

     Total returns for the Vanguard Municipal Bond Fund Portfolios in fiscal
1997 proved to be more rewarding than in the previous year. Total return
consists, of course, of capital appreciation (or depreciation) plus interest
income. As in fiscal 1996, the lion's share of each Portfolio's total return in
fiscal 1997 came from interest income. In addition, the decline in interest
rates over the past 12 months provided some degree of capital appreciation for
most of our Portfolios. The increases in share price were highest for those
Portfolios embracing the greatest amount of market risk. Conversely, these
longer-term Portfolios would have experienced the greatest share-price declines
if interest rates had moved higher during the year. In general, then, each of
the Portfolios performed in accordance with its stated risk parameters.

"IT'S THE ECONOMY, . . ."

In March the Federal Reserve Board decided that the economy's robust growth
rate was worrisome and warranted a rise in short-term interest rates. On March
25, the Fed therefore increased the federal funds rate from 5.25% to 5.50%. At
the time, the move was widely viewed as likely to be the first in a series of
increases in short-term rates. However, five months later, as our fiscal year
came to a close, the March adjustment remained the Fed's only change.
Inflation, as measured by both the Producer Price Index and Consumer Price
Index, has been remarkably restrained. Many economists and Federal Reserve
Board governors do not understand why.  Some ascribe the benign inflation trend
to increased productivity fostered by technological innovation. Workers are
able to produce more owing to increased use of advanced technology. Others
believe that U.S. workers have been so traumatized by the corporate
"downsizings" of recent years that they are willing to sacrifice higher wages
for increased job security.

     The domestic economy enjoyed the best of all worlds in the second half of
fiscal 1997. It has maintained an annual growth rate above 3%, as measured by
changes in Gross Domestic Product, for the last three quarters. The
unemployment rate dropped by August





                                       7
<PAGE>   10
to 4.9%, well below the level long believed to produce increases in labor
costs. The Consumer Confidence Index survey of consumer attitudes suggests that
the public is very optimistic about economic prospects. The question being
asked by many economists is: How long can these benign conditions last? Some
storm clouds may be faintly visible on the horizon. The recent United Parcel
Service strike could be a precursor of future labor unrest. The August
employment report noted that more people were voluntarily leaving their jobs,
presumably because of greater confidence in their ability to find better or
higher-paying jobs elsewhere.

     The strength of the economy had some very positive effects for all
investors. For one thing, it enabled Republicans and Democrats to agree on the
federal budget. Last year, the federal government sustained a series of
shutdowns before Congress reached a budget agreement. This year, when budget
negotiators reached an impasse, new projections of higher tax revenues allowed
both sides to claim victory. It seems that government operates very smoothly
when its coffers are full. The new, rosier projections were based, in part, on
the economy's current health. Included in the budget agreement was a reduction
in the capital gains tax rate: Investors who have gains on the sale of assets
owned longer than 18 months will now be subject to a maximum capital gains tax
of 20% rather than 28%.

     The stock market continued its protracted rise, reaching record highs in
early August. Investors poured cash into equity funds throughout the fiscal
year, adding fuel to the explosive growth in stock prices. The equity markets
relinquished some of their recent gains in the final three weeks of the fiscal
year. At the period's end on August 31, the Dow Jones Industrial Average and
the Standard & Poor's 500 Composite Stock Price Index were down 7.7% and 6.3%,
respectively, from records attained on August 6.

CONCLUSION

The seven Portfolios of Vanguard Municipal Bond Fund performed in line with
their investment objectives in fiscal 1997. Their performance was what one
would expect, given their clearly defined investment charters. Each Portfolio
provides a degree of share-price stability and income consistent with the
position of its average maturity on the yield curve.

     Looking forward, the major question facing the market is how long the
economy can operate at such low levels of unemployment and such strong levels
of growth without showing signs of increases in the rate of inflation. If
inflation does begin to accelerate in fiscal 1998, share-price volatility can
also be expected to increase. Whatever the outcome, the Portfolios of Vanguard
Municipal Bond Fund will continue to provide total returns consistent with our
well-defined investment objectives in the most cost-efficient manner possible.

fluctuate in response to a change in interest rates.  To see how the price
could shift, multiply the portfolio's duration by the change in rates. If
interest rates rise by one percentage point, the share price of a portfolio
with an average duration of five years would decline by about 5%. If rates
decrease by a percentage point, the portfolio's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by the portfolio
reach maturity (or are called) and are repaid. In general, the longer the
average maturity, the more a portfolio's share price will fluctuate in response
to changes in market interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a portfolio's securities holdings by credit-rating
agencies. The agencies make their judgment after appraising an issuer's ability
to meet its obligations.  Quality is graded on a scale, with Aaa or AAA
indicating the most creditworthy bond issuers and SP-1 or MIG-1 indicating the
most creditworthy issuers of money market securities.

BETA. A measure of the magnitude of a portfolio's past share-price fluctuations
in relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a portfolio with a
beta of 1.20 would have seen its share price rise or fall by 12% when the
overall market rose or fell by 10%.

CASH RESERVES. The percentage of a portfolio's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing investments.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a portfolio's securities by
credit rating can help in gauging the risk that returns could be affected by
defaults or other credit problems.

DISTRIBUTION BY MATURITY. An indicator of interest-rate risk. In general, the
higher the concentration of longer-maturity issues, the more a portfolio's
share price will fluctuate in response to changes in interest rates.

EXPENSE RATIO. The percentage of a portfolio's average net assets used to pay
its annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

INVESTMENT FOCUS. This grid indicates the focus of a portfolio in terms of two
attributes: average maturity (short, medium, or long) and average credit
quality (high, medium, or low).

LARGEST STATE CONCENTRATIONS. An indicator of diversification. The less
concentrated a portfolio's holdings of bonds, the less the portfolio will be
hurt by any financial problems in a single state or region.

NUMBER OF ISSUES. An indicator of diversification. The more separate issues a
portfolio holds, the less susceptible it is to a price decline stemming from
the problems of a particular bond issuer.

R-SQUARED. A measure of how much of a portfolio's past returns can be explained
by the returns from the overall market (or its benchmark index). If a
portfolio's total return were precisely synchronized with the overall market's
return, its R-squared would be 1.00. If a portfolio's returns bore no
relationship to the market's returns, its R-squared would be 0.

YIELD. A snapshot of a portfolio's interest income. The yield, expressed as a
percentage of the portfolio's net asset value, is based on income earned by the
portfolio over the past 30 days (7 days for money market portfolios) and is
annualized, or projected forward for the coming year.

YIELD TO MATURITY. The rate of return an investor would receive if the
securities held by the portfolio were held to their maturity dates.

FINANCIAL STATEMENTS
August 31, 1997

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Municipal Bond Fund Portfolios, and the Report of
Independent Accountants 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 a 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 are not required to report
a Portfolio Turnover Rate.

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:
Bonds, and temporary cash investments acquired over 60 days to maturity, are
valued using the latest bid prices or using valuations based on a matrix system
(which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.

    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 August 31, 1997, the Fund had contributed capital aggregating
$1,444,000 to Vanguard (included in Other Assets), representing 7.2% 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 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 administrative
expenses. The Fund's custodian bank has also agreed to reduce its fees when the
Fund maintains cash on deposit in the noninterest-bearing custody account. For
the year ended August 31, 1997, directed brokerage and custodian fee offset
arrangements reduced expenses by:

E.  Capital gains distributions are determined on a tax basis and may differ
from realized capital gains for financial reporting purposes due to differences
in the timing of realization of gains. For federal income tax purposes, the
Portfolios had the following capital gains available for distribution at August
31, 1997, or capital losses available to offset future capital gains:

VANGUARD MUNICIPAL BOND FUND
FINANCIAL STATEMENTS
August 31, 1997

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 appear 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.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and
Board of Directors of
Vanguard Municipal Bond Fund

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights appearing in the Annual Report to Shareholders present fairly, in all
material respects, the financial position of Money Market Portfolio, Short-Term
Portfolio, Limited-Term Portfolio, Intermediate-Term Portfolio, Insured
Long-Term Portfolio, Long-Term Portfolio, and High-Yield Portfolio (separate
portfolios of Vanguard Municipal Bond Fund, hereafter referred to as the "Fund")
at August 31, 1997, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at August
31, 1997 by correspondence with the custodian and brokers and the application of
alternative auditing procedures where securities purchased had not been settled,
provide a reasonable basis for the opinion expressed above.
