OUR CREW MAKES THE DIFFERENCE

Throughout our 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,

Vanguard Variable Insurance Fund's fiscal year ended September 30, 1997, was a
marvelous period to be an investor. U.S. stock markets produced tremendous
gains, bonds and international stocks had solid returns, and even money market
instruments earned returns well above their long-term average and the inflation
rate. All nine of the Fund's Portfolios produced positive returns for the year,
and six of the nine outpaced comparable mutual funds.

     The table at right presents the total return (capital change plus
reinvested dividends) of each Portfolio for the fiscal year, along with the
results of the average comparable mutual fund and an appropriate unmanaged
market benchmark. The total return figures reflect the change in net asset
value for each Portfolio, adjusted to include the reinvestment of any income or
capital gains distributions. Performance Summaries for the Portfolios,
including a breakdown of each fiscal year's returns into their income and
capital components, are presented on pages 31-39.

FISCAL 1997 PERFORMANCE OVERVIEW

For the third year in a row, the U.S. stock market shot higher in the twelve
months ended September 30, bringing the three-year cumulative return of the
Standard & Poor's 500 Composite Stock Price Index to an incredible +119%.
Economic conditions remained ideal for equity investors, as business activity
continued to expand without engendering increases in inflation or long-term
interest rates, and corporate profits continued to burgeon. On balance during
the year, the yield on the benchmark 30-year U.S.  Treasury bond declined by
0.49 percentage point to 6.43%. On the short-term side, by contrast, rates rose
slightly and the yield on the three-month U.S. Treasury bill closed the fiscal
year at 5.11%, up 0.08 percentage point from the level on September 30, 1996.
The general decline in long-term interest rates raised bond prices, bringing
the total return (including interest payments) of the Lehman Brothers Aggregate
Bond Index to +9.7%.





                                       1
<PAGE>   4
     This interest rate environment, along with the splendid economic
fundamentals, elevated the already-high spirits of investors so that by
year-end stock prices were at or near historic highs in relation to such
fundamentals as dividends, earnings, and book values. Most foreign stock
markets (Japan and several southeast Asian markets were notable exceptions)
also enjoyed strong returns during fiscal 1997, although returns to U.S.
investors were diminished by a strengthening of the U.S. dollar versus most
other currencies. Equity returns were especially strong in Europe and Latin
America.

     The magnitude of the returns earned by each of our Portfolios during the
twelve months ended September 30 was determined largely by the type of assets
each holds.  A summary of the year's results follows.

FIXED-INCOME PORTFOLIOS

The MONEY MARKET PORTFOLIO earned +5.5% in fiscal 1997, comfortably ahead of
the +4.9% return earned by the average money market mutual fund. Short-term
interest  rates remained within a narrow band during fiscal 1997, with the rate
on three-month U.S.  Treasury bills fluctuating from a low of 4.84% in June to
a high of 5.40% in March. There is no secret to our consistent lead over other
money market funds: Our main advantage is our lower expense ratio (expenses for
the year as a percentage of average net assets). In fiscal 1997, our expense
ratio was 0.21% ($2.10 per $1,000 in assets), more than one-half percentage
point below the 0.79% expense ratio of the average money market fund.

     Our HIGH-GRADE BOND PORTFOLIO benefited from falling interest rates during
the year. Its +9.6% return outpaced the average intermediate-term U.S.
government bond fund by 1.4 percentage points and came within a whisker of the
+9.7% return on the Lehman Aggregate Bond Index, a good benchmark for the
taxable bond market.

     The HIGH YIELD BOND PORTFOLIO reached its first anniversary in June. Its
+14.1% return during the fiscal year reflected the strength of the high-yield
bond market, which was buoyed not only by falling interest rates but by a
general strengthening in the balance sheets of many corporations. The
Portfolio's return lagged that of the average competing fund by 1.5 percentage
points, largely because we do not hold some of the more speculative bonds in
the high-yield arena, which performed quite well in this bullish period.  We
believe that over time our remarkably low expense ratio (0.31% versus 1.39% for
the average high-yield bond fund) will enable us to provide competitive yields
and returns without reaching for the additional yield offered by the
lowest-grade bonds.

BALANCED PORTFOLIO

In a bullish market for both stocks and bonds, our BALANCED PORTFOLIO earned
+27.6%, the highest annual return in its six and one-half years of operation.
The Portfolio out-performed the average balanced fund by a comfortable margin
of 3.6 percentage points.  This excellent absolute return fell short of our
unmanaged benchmark--a composite index weighted 65% in the S&P 500 Index and
35% in high-quality, long-term bonds--largely because of the Portfolio's
slightly defensive stance. The Portfolio held about 62% of its assets in
stocks, 3 percentage points less than our benchmark.

DOMESTIC EQUITY PORTFOLIOS

The EQUITY INDEX PORTFOLIO provided a return of +40.3%, more than 4 percentage
points above the typical growth and income fund and just a smidgen below the
+40.4% return on its benchmark S&P 500 Index. This close tracking of the Index
is a notable achievement because the Index exists only "on paper" and bears
none of the operating expenses





                                       2
<PAGE>   5
or transaction costs incurred by actual investment portfolios. Our expense
ratio of 0.23% in fiscal 1997 is more than 1 percentage point lower than that
of the average growth and income fund, giving the Portfolio a nice head start
each year versus competing funds.

     Our EQUITY INCOME PORTFOLIO earned +38.1%, surpassing the average equity
income fund by nearly 4 percentage points. We trailed the return of the S&P 500
Index by 2.3 percentage points largely because of our relatively conservative
investment strategy, which emphasizes value-oriented, high-yielding stocks.
During fiscal 1997, growth stocks in the S&P 500 Index outpaced value
stocks--returning +41.5% and +39.2%, respectively--making it difficult for a
value-oriented portfolio to beat the Index. The Portfolio's focus on
dividend-paying common stocks meant that we were underweighted in technology
stocks, many of which pay low or no dividends. Technology stocks--with total
returns of nearly +70%--were the best-performing segment of the S&P 500 Index
during fiscal 1997.

     Our GROWTH PORTFOLIO, after significantly outperforming its comparative
benchmarks in fiscal 1996, lagged both the average growth fund and the S&P 500
Index in fiscal 1997. Even so, our return of +28.8% was very strong on an
absolute basis, bringing our cumulative return for the three years ended
September 30 to 117%. Most of our shortfall versus the Index in fiscal 1997 was
the result of our lagging performance in the high-flying technology sector.
Some of the very best-performing technology names were absent from our
holdings.

     Our SMALL COMPANY GROWTH PORTFOLIO earned +22.2% in its first full fiscal
year of operations, a return that was solid on an absolute basis but paled in
relation to returns of +30.4% for the average small-company stock fund and
+33.2% for the Russell 2000 Index. Nearly all the shortfall versus the Index
was the result of subpar stock selections in two industry sectors--technology
and producer durables.

INTERNATIONAL PORTFOLIO

Foreign stock markets for the most part rose nicely during fiscal 1997,
although few matched Wall Street's ebullient atmosphere. Our INTERNATIONAL
PORTFOLIO earned +18.6%, which outpaced both the +18.4% return for the average
international stock fund and the +12.5% return for the Morgan Stanley Capital
International Europe, Australasia, Far East Index. The EAFE Index returned
+22.3% in local currency terms, but the dollar's rise against most currencies
sliced nearly 10 percentage points off the returns received by U.S. investors.
European bourses were particularly buoyant, with returns exceeding +40% in
local currencies and +35% in dollar terms. Japan's stock market slumped, beset
by ongoing doubts about both the nation's economic prospects and the bad-debt
problems of the country's banks. However, our adviser's selections of  Japanese
stocks produced solid gains, enabling the Portfolio to handily beat the EAFE
Index. Several smaller Asian markets posted large losses because currency
devaluations exacerbated corporate debt problems, while emerging markets in
Latin America generally posted strong returns.

LONGER-TERM PERFORMANCE OVERVIEW

The table on the following page presents the lifetime records of all nine
Portfolios. With the exceptions of our High Yield Bond and Small Company Growth
Portfolios, which have been in operation only 16 months, each of the Portfolios
has outperformed its peer group since the Portfolio's inception.

     We are pleased with our record so far. However, we emphasize that the past
returns shown in the table on page 4 should not be regarded as guides to our
Portfolios' future returns. Since our Portfolios began operations, returns from
U.S. stocks and bonds have





                                       3
<PAGE>   6
been above long-term historical norms, which suggests the strong possibility
that future returns will be less generous. But short-term movements in the
financial markets are highly unpredictable--indeed, we sounded a cautious note
about "rougher seas ahead" in our letter to you last year. All we can say with
certainty is that returns will fluctuate from year to year.

</TABLE>


       Despite the unpredictability of absolute returns, we are confident that
our Portfolios can provide strong relative returns over time.  In our quest to
provide higher long-term returns than our competitors, we are aided by our
lower costs, which year in and year out give us an edge over our peers. That
"expense advantage"--ranging from nearly 0.6% last year for our Money Market
Portfolio to approximately 1.2% for our International Portfolio--is one that we
believe will endure and will enhance your long-term returns.

IN SUMMARY

Since its creation in 1991 as a way for investors to accumulate assets in
variable annuity or variable life insurance contracts, Vanguard Variable
Insurance Fund has met with increasing acceptance and has reached nearly $3
billion in assets. Certainly part of our growth can be credited to the
generally favorable market conditions since 1991 (and, indeed, since the early
1980s). However, we also believe that a good portion of our success is due to
our strategy of providing a high-quality, clearly defined, and professionally
managed set of investment options at the lowest reasonable cost.

     We pledge to adhere to our strategy, just as we advise investors to "stay
the course" with a balanced, long-term investment program that suits their
financial objectives and circumstances, their time horizons, and their
tolerance for the markets' ups and downs. For variable annuity and variable
life contract holders, Vanguard Variable Insurance Fund provides a means to
personally tailor and adjust such a customized, long-term program.

  Special Notice To Shareholders Of The Small Company Growth Portfolio

  The Fund's Board of Trustees has approved a change to the investment advisory
  agreement between the Small Company Growth Portfolio and its investment
  adviser, Granahan Investment Management, Inc. Under the current agreement,
  dated May 1, 1996, Granahan's advisory fees are increased or decreased based
  upon the Portfolio's investment performance compared with that of the Russell
  2000 Index. The revised agreement, which takes effect on January 1, 1998,
  will adopt a new performance benchmark for determining the incentive/penalty
  adjustment to Granahan's fees.

  NEW PERFORMANCE BENCHMARK

  The Portfolio's new performance benchmark is the Small Company Growth Fund
  Stock  Index. This index comprises the common stocks held by the 25 largest
  small-company stock mutual funds (at the end of 1996, this amounted to
  approximately 1,800 stocks).  Morningstar, Inc., an independent consultant,
  maintains the Small Company Growth Fund Stock Index exclusively for Vanguard.

  WHY CHANGE THE PERFORMANCE BENCHMARK?

  The Portfolio's current performance benchmark--the Russell 2000
  Index--includes many value stocks that are inconsistent with the Portfolio's
  growth-stock orientation. In addition, because it is a market
  capitalization-weighted index, the Russell 2000 does not reflect the
  characteristics and performance of the Portfolio's direct competitors--other
  small-company growth funds. Overall, the Fund's Trustees and officers believe
  that the Small Company Growth Fund Index is a more appropriate performance
  benchmark for determining Granahan's incentive/penalty fees.

  NO OTHER SIGNIFICANT CHANGES

  There will be no other significant changes to the terms of the investment
  advisory agreement. Granahan will continue to manage the investment and
  reinvestment of the Portfolio's assets, subject to the control of the Fund's
  officers and Trustees. The Portfolio will continue to pay Granahan a basic
  advisory fee at the end of each fiscal quarter. On an annualized basis, this
  fee amounts to 0.15% of the average month-end net assets of the Portfolio for
  the quarter. As under the current agreement, Granahan's basic advisory fee
  will be increased or decreased depending on the Portfolio's total return
  compared with that of a performance benchmark. Although this performance

     For the fiscal year ended September 30, 1997, the Small Company Growth
  Portfolio paid approximately $85,000 in advisory fees to Granahan. This
  amount  represented an effective annual rate of 0.12% of the Portfolio's
  average net assets for the year, including a base fee of $107,000 and a
  performance penalty of $22,000 (0.03% of average net assets). For fiscal
  1997, Vanguard Explorer Fund paid Granahan advisory fees representing an
  effective annual rate of approximately 0.20% of the Fund's average net
  assets.

  OTHER BACKGROUND INFORMATION

  In 1993, the Fund received permission from shareholders and the U.S.
  Securities and Exchange Commission to enter into new investment advisory
  agreements without the delay and expense of a shareholder vote. This
  permission was granted subject to a number of conditions, including the
  requirement that shareholders be notified of any changes to the Fund's
  investment advisory agreements. Shareholders of the Portfolio have never
  voted on its investment advisory agreement.

THE MARKETS IN PERSPECTIVE
Year Ended September 30, 1997


U.S. EQUITY MARKETS

For stock investors, the fiscal year ended September 30, 1997, was nothing
short of spectacular. Indeed, it was a very good year for almost all types of
investors: 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 instead have accelerated at this point in the economic cycle.
The most widely accepted explanation for this paradox involves substantial
productivity gains that are not apparent from the measures in use today.
Reports indicate that even the Federal Reserve Board is otherwise at a loss to
explain the current "economic nirvana."

     Large-capitalization U.S. common stocks performed extraordinarily well
during the past year, as illustrated by the 40.4% gain of 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. Among the best-performing sectors were
technology and financial services, with increases of 67.5% and 54.1%,
respectively.  The surge in technology reflects robust corporate spending on
this industry's products, particularly desktop computers, networking equipment,
and software. Despite posting an aggregate gain of 24.4%, consumer
discretionary stocks could be considered laggards.  (Clearly, the market has
shown amazing gains when a 24% advance over a one-year period can be viewed as
inadequate.)

     The performance of small-company stocks, while they failed to match the
outsized advance of the S&P 500 Index, was more than respectable during this
period--the Russell 2000 Index gained 33.2%. The difference in return between
large and small companies is partly the result of 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" 26.0% in
aggregate, over 40 percentage points less than their large-company
counterparts.

U.S. FIXED-INCOME MARKETS

In the fixed-income markets, rates fell across the yield curve, rewarding
investors with higher total returns. For example, the rates on 1-, 5-, 10-, and
30-year U.S. Treasury issues fell 0.25%, 0.47%, 0.58%, and 0.49%, respectively,
from September 30, 1996, to September 30, 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 9.7%
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 14.5% 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 12.5% in dollars. This Index's relatively modest
performance masks the  fact that the European markets were very strong during
the past year, gaining 48.1% in local currency terms and 35.4% in dollars,
while many of the Pacific Basin markets were weak, down 5.4% in local currency
and 13.1% in dollars. The Japanese market declined 15.7% in dollars and 8.6% in
yen terms. Despite the competitive benefits of a weak currency, Japan continued
to struggle with a weak domestic economy and an oversupply of equities. Smaller
Asian markets, such as Malaysia (losing 28.5% in local terms and 44.7% in
dollars), suffered from a variety of challenges, chiefly overvalued currencies
and high interest rates.

REPORT FROM VANGUARD FIXED INCOME GROUP
Money Market Portfolio and High-Grade Bond Portfolio


In the fiscal year ended September 30, 1997, bond market investments produced
healthy returns as intermediate- and long-term interest rates fell by roughly
one-half percentage point. On top of the 6% to 7% in income earned during the
period, the general decline in market rates resulted in price appreciation,
which varied along with the maturities of bonds. In a rare "win-win" situation,
money market investors also enjoyed a slight increase in returns because of
rising interest rates for very short-term securities.

     The seemingly contradictory pattern of rising short-term rates and falling
long-term rates was due to a combination of preemptive tightening of monetary
policy by the Federal Reserve Board and unexpectedly good inflation data
throughout the year. In March of this year, the Fed engineered a 0.25% increase
in the federal funds rate, the agency's first tightening of monetary policy
since early 1995. Remarks by Fed officials then--and again more
recently--indicated that they felt the economic headwinds (primarily job
insecurity) that had kept inflationary pressures in check had largely
dissipated. Low unemployment and rising wages have fueled consumer confidence
and propelled the economy's annual growth rate above the speed limit of 2% to
2.5% that had been viewed as noninflationary. Still, inflation has remained
surprisingly low during this period of rapid growth and has boosted the
confidence of long-term bond investors that price pressures will remain
subdued. This confidence has caused the inflation risk premium typically
factored into the prices of long-term bonds to shrink, flattening the yield
curve (i.e., reducing the gap between yields on short-term and long-term
bonds).

     In managing the Money Market Portfolio of the Vanguard Variable Insurance
Fund, we have somewhat reduced the average maturity of the Portfolio's
holdings. The economy's continued strong growth is likely to force the Fed to
raise short-term rates again, particularly in light of the dwindling supply of
workers available to sustain the expansion. The shorter term of the Portfolio's
holdings will cause its yield to more quickly reflect changes in market rates,
which will benefit the  Portfolio if rates rise.  Also, we are steering our
investments into the high-quality end of the creditworthiness spectrum. This
should come as no surprise to shareholders who have invested with us for any
length of time. Our bias toward high-quality securities is long-standing, and
it has been reinforced by the situation in today's taxable money markets, which
offer only the thinnest margin of additional yield for issues of less than top
quality. This thin margin is, over time, dwarfed by the expense advantage of
Vanguard portfolios versus competing funds.

     Over the last six months, the bond market experienced a moderate decline
in yields, reflecting investors' expectations that low inflation rates will
continue.

The Treasury yield curve flattened slightly, with yields on 2-year issues
declining by 0.6% and yields on 30-year issues declining by 0.7%.

     On balance over the full fiscal year ended September 30, 1997, 2-year
rates declined by 0.3%, and yields on 10- and 30-year bonds declined by
approximately 0.6% and 0.5%, respectively.

     The table below presents the performance of the various sectors of the
Lehman Aggregate Bond Index--a good proxy for the entire taxable bond

</TABLE>


     Corporate bonds were the best-performing category for both periods. This
was the result of (1) higher initial yields offered by the corporate sector;
(2) a narrowing of spreads between yields on corporate bonds and yields on U.S.
Treasury securities, which was associated with stronger corporate balance
sheets; and (3) the longer average maturity of the corporate sector.

     The High-Grade Bond Portfolio is designed to closely replicate the
performance of the Lehman Aggregate Bond Index. For the 6-and 12-month periods
ended September 30, the Portfolio's returns were 7.03% and 9.60%, respectively,
compared with the Index returns of 7.12% and 9.71% for the periods. Adjusted
for expenses and transaction costs (neither of which affect the theoretical
Index), the Portfolio's tracking of the benchmark was excellent, actually
outpacing it by 0.1 percentage point for the  6-month period and by 0.3
percentage point for the 12-month period.

     As of September 30, the Portfolio comprised 35% government bonds, 29%
corporate bonds, 5% foreign bonds (denominated in U.S.  dollars), and 31%
mortgage-backed securities.

INVESTMENT PHILOSOPHY

MONEY MARKET PORTFOLIO

The adviser believes a portfolio can provide the highest level of current
income consistent with capital preservation and liquidity by holding
high-quality money market instruments issued by financial institutions,
nonfinancial corporations, and the U.S. government.

HIGH-GRADE BOND PORTFOLIO

The adviser believes a portfolio can provide sustainable, high levels of
current income by holding an extremely well-diversified group of U.S.
government, corporate, and mortgage-backed bonds that parallels the performance
of the Lehman Brothers Aggregate Bond Index.

REPORT FROM WELLINGTON MANAGEMENT COMPANY, LLP
High Yield Bond Portfolio


This is our third letter to shareholders since the High Yield Bond  Portfolio
began operations on June 3, 1996. For the 6- and 12-month periods ended
September 30, 1997, the Portfolio has returned 9.0% and 14.1%, respectively.
Yields on 10-year U.S. Treasury bonds have declined by approximately 60 basis
points (0.60 percentage point) since the beginning of the fiscal year, and by
some 80 basis points since its midpoint on March 31. As we mentioned in the
annual report last fall, below-investment-grade bonds usually outperform
higher-quality bonds at times when investors are anticipating strong economic
growth and interest rates are rising moderately. During the most recent
six-month period, we experienced strong growth but falling interest rates--an
unusual combination. In general, the high-yield market managed to keep pace
with the investment-grade market as the general level of interest rates fell.

     Investors continue to favor below-investment-grade bonds because the
annual default rate by corporate bond issuers has fallen to historically low
levels. We expect moderate economic growth to continue, so we also expect the
default rate to remain low. Given this constructive economic outlook, we
continue to emphasize bonds issued by large companies sensitive to the economic
cycle. We do not anticipate any major problems in the economy that would cause
your Portfolio to suffer any meaningful deterioration in credit quality.

     We remain very selective with respect to creditworthiness, however, in
examining the large number of new issues coming to market. With substantial
cash flows into high-yield bond funds and a broader acceptance of high-yield
bonds by investors who have traditionally bought only investment-grade
securities, the quality of the companies coming to market could decline.
Twenty-five percent of total high-yield bond issuance through the first half of
the calendar year has been from Yankee issuers (foreign issuers whose
securities are denominated in U.S. dollars). Sixty-three percent of the Yankee
issuance in the January-June period was by sovereign governments or
corporations in Latin America. Two years ago, by contrast, only 5% of such
bonds were issued by Latin American borrowers. Your Portfolio does not
currently hold bonds from issuers in Latin America, but we continue to monitor
their willingness and ability to service their debts in a timely fashion.

     We remain committed to conducting in-depth credit research on a
company-by-company basis and to emphasizing diversification in the Portfolio's
construction. The Portfolio now owns more than 150 issues representing a broad
range of industries and companies.  The Portfolio's holdings continue to be
focused on cash-paying issues rated B or better. Our emphasis, in short, is on
relatively higher-quality bonds within the below-investment-grade market.

Earl E. McEvoy, Senior Vice President and
Portfolio Manager

October 14, 1997


INVESTMENT PHILOSOPHY

The adviser believes a diversified group of high-yielding, medium- and
low-quality corporate bonds--selected after rigorous credit assessment--can
provide sustainable, high current income as well as some potential for capital
growth.

REPORT FROM WELLINGTON MANAGEMENT COMPANY, LLP
Balanced Portfolio


The Balanced Portfolio earned a 27.6% return during the fiscal year ended
September 30, 1997. The stock market increased sharply during the period, which
benefited the sizable portion (62%) of the Portfolio invested in equities. The
remainder of the Portfolio's investments, which are in fixed-income securities,
also provided attractive returns as interest rates declined moderately. For the
fiscal year, the equity portion of the Portfolio gained 37.2% and the
fixed-income securities segment returned 13.0%.

     In the equity portion of your Portfolio, we maintain a large
representation in the financial services, health-care, basic materials, energy,
and auto & transportation sectors. During fiscal 1997, the Portfolio benefited
from its large exposure to financial services and its underweighting versus the
overall market in consumer stocks. The latter group was hurt by investor
expectations that profits on foreign operations would suffer because of the
high level of the dollar relative to other currencies.  On the other hand, the
Portfolio's low exposure to technology stocks, which generally do not provide
the dividend income we look for in our equity selections, held us back a bit
since this sector enjoyed the biggest gains during fiscal 1997.

     During the year, we added several new names in a number of sectors,
including H.J. Heinz, consumer staples; Fannie Mae and Marsh & McLennan,
financial services; Occidental Petroleum, energy; Boeing and Lockheed Martin,
producer durables; and IBM, technology. These were funded by sales of holdings
where we saw less  opportunity, or, as in the case of Northrop Grumman, where a
takeover proposal was received.

     Investors in fixed-income securities generally continue to be more
concerned than equity investors about a possible resurgence in inflation. As a
result, bond yields are at a premium over the rate of inflation. We find the
yields on long-term bonds quite attractive in the current environment.

     Stocks performed extremely well during the year, despite setbacks in March
and August when investors began to worry about the economy's ability to sustain
its high growth rate without inflation. So far these corrections have turned
out to be of minor importance. However, we are concerned that inflationary
pressures may emerge and that the growth rate of corporate profits may slow
from its rapid pace in recent years. Therefore, we are keeping the portion of
the Portfolio dedicated to equities at the low end of our normal 60%-70% range.

     The Portfolio continues its approach of investing in a conservative manner
in both the equity and fixed-income markets. As the equity market continues its
advance to higher territory, we believe this approach is a wise course.

Ernst H. von Metzsch, Senior Vice President and
Portfolio Manager
Paul D. Kaplan, Senior Vice President and
Portfolio Manager

October 14, 1997


INVESTMENT PHILOSOPHY

The adviser believes that a reasonable level of current income and long-term
growth in capital can be achieved without undue risk by holding 60% to 70% of
assets in common stocks and the balance in fixed-income securities. Consistent
with this approach, dividend-paying stocks dominate the equity segment of the
Portfolio, while long-term, high-quality corporate, U.S. Treasury, and
mortgage-backed securities make up the bond segment.

REPORT FROM NEWELL ASSOCIATES
Equity Income Portfolio


The Equity Income Portfolio earned 38.1% for the fiscal year ended September
30, within striking distance of the 40.4% return of the S&P 500 Index and well
ahead of the 34.2% return achieved by the average equity income fund.

     Newell Associates uses its Relative Yield Strategy to manage the
Portfolio. We buy stocks of large U.S. companies when they are out of favor and
sell them when investors become overly enthusiastic about their prospects. The
process results in a conservative portfolio, quite broadly diversified, with
low turnover and a dividend yield well above that of the market. The
Portfolio's current yield is almost twice that of the S&P 500 Index.

     Ironically, in explaining the Portfolio's performance relative to the S&P
500 Index in recent years, it has been necessary to talk about computer-related
technology stocks--a group that is not in the Portfolio because such stocks pay
low or no dividends. In the S&P 500, by contrast, technology is now the
second-largest sector, accounting for roughly 14% of the market capitalization,
up from less than 10% only five years ago. Technology therefore is a critical
factor in the performance of the Index, overwhelming the influence of more
traditional industry sectors. Fiscal 1997 was another chapter in this ongoing
saga. The technology sector soared nearly 70%, far higher than the Index's
40.4% total return, to which the sector contributed almost 8 percentage points.
Only financial stocks came remotely close to making such a contribution to the
Index return.

     The most important contributors to the Portfolio's return in the fiscal
year were the financial, drug, and petroleum sectors.  Since the 1990-91
recession, banks, as well as savings and loans and insurance companies, have
benefited from declining interest rates and a friendly regulatory environment.
These financial stocks have enjoyed enormous price increases since then, and
their strong performance during fiscal 1997 continued the phenomenon.

     The drug stocks also remained strong during the past year. We acquired
these companies when they were deeply out of favor with investors who were
frightened in 1993 about the potential consequences of proposed national
health-care legislation. The stocks have since recovered much of their luster
in the eyes of investors. Although we have sold some holdings in the group,
others still have dividend yields high enough to keep them in the Portfolio.
The pharmaceutical group remains overweighted in the Portfolio versus the S&P
500 Index.

     Petroleum stocks also contributed significantly to the Portfolio's strong
performance during the year, as energy prices held up better than many market
participants had expected.

Roger D. Newell, Chairman

October 14, 1997


INVESTMENT PHILOSOPHY

The adviser believes that a portfolio made up of undervalued stocks, most of
which offer high dividend yields compared to their past levels and to the
overall market, can provide a high level of current income, the potential for
capital appreciation, and below-average price volatility for a stock mutual
fund.

REPORT FROM LINCOLN CAPITAL MANAGEMENT COMPANY
Growth Portfolio


Enormous returns were earned from equity investments in the fiscal year ended
September 30, 1997. The S&P 500 Index generated a 40.4% return. Your Growth
Portfolio enjoyed a substantial gain for the third consecutive fiscal year.
However, after good relative performance in prior years, our 28.8% return in
fiscal 1997 was quite a bit behind the market.

     What caused the lags? Here are some things that didn't happen:

     1. Our industry diversification did not shift much. The only material
change involved technology stocks. This sector's representation in the
Portfolio rose from 16% to 21% during the year, a beneficial change.

     2. There were no big industry bets. The Portfolio's industry weightings
are quite similar to those of the S&P/BARRA Growth Index (one reasonable
benchmark for measuring our performance). One minor bet is that the Portfolio
holds no stocks in the communications sector, which accounts for 3% of the
Growth Index.

     3. The continuity of the Portfolio holdings was not disrupted. Of the 10
largest current holdings, 5 were similarly prominent a year ago (see the
accompanying table). Ditto for two years ago. Five of the largest
commitments--Intel, Philip Morris, Coca-Cola, Procter & Gamble, and
PepsiCo--have been among the Portfolio's top dozen holdings for three or four
years. So the character of the holdings is quite stable. The number of holdings
is 57, down one from the end of fiscal year 1996. Turnover during the past 12
months was a moderate 38%.

*In the top ten a year ago.


     Most of the shortfall versus the S&P 500 and S&P/BARRA Growth Indexes
related to selections in technology--we didn't own Microsoft throughout the
period (it had seemed fully priced), Lucent, or Compaq, all of which zoomed. We
did own some moderate-sized tech companies that sagged. Our energy and business
service selections, and several forays into more moderately sized,
consumer-type companies, didn't prove successful. As you can imagine, even a
few stubbed toes were painful in such a strong bull market.  Grimacing, we
apologize.

     Looking back at three good years, both absolute and relative, we are

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved
by emphasizing investments in high-quality, established growth companies whose
stocks  sell at reasonable prices considering their expected earnings and
compared to values in the broad stock market.

REPORT FROM GRANAHAN INVESTMENT MANAGEMENT, INC.
Small Company Growth Portfolio


Small-capitalization stocks returned to favor in recent months after  several
years of being outperformed by larger stocks. A chief reason for the turnaround
was the relatively faster growth of earnings for many small growth companies.
Another factor was the strengthening of the dollar, which tends to do less harm
to small companies than to large companies, as the latter typically derive more
revenue and earnings from international operations.

     During the six months ended September 30, 1997, the Small Company Growth
Portfolio earned a total return of 35.3%, while the Russell 2000 Index of
small-cap stocks returned 33.5%. This positive comparison, however, did not
make up for our poor first-half performance. For the full fiscal year, the
Portfolio's return of  22.2% lagged the 33.2% return of the Russell 2000 Index.

     Technology stocks rebounded nicely in the second half of the year. Other
strong areas included consumer time-share properties, brokerage firms, and
energy service companies. The health-care segment of the small-cap market was a
laggard.

INVESTMENT THEMES

Several investment themes have been at work in the Portfolio since its
inception in June 1996:

     Air freight forwarders (such as Expeditors, Air Express, and Circle) have
benefited from strong global trade plus a trend among shippers to concentrate
their outsourcing of logistics management to fewer vendors. Price/earnings
ratios in this group have risen significantly, so we did some selling.

     Energy service stocks (Halter, Hvide, Smith, and Trico) are benefiting
from a sharp rebound in oil-drilling activity, particularly in the Gulf of
Mexico. Valuations of these stocks have also risen.

     Industry consolidators (Service Experts and Comfort Systems) are
benefiting from a trend toward combining operators in fragmented industries, in
their case heating, ventilation, and air-conditioning contractors.

     Certain Internet and Intranet companies (E*TRADE, Netscape, Object Design,
QuickResponse Services, and Security Dynamics) are achieving sustainable
profitability. Valuations in this sector have generally risen.

     Time-share companies (including Fairfield Communities, Vistana, and
Trendwest) have enjoyed good sales and earnings growth.

     Looking ahead, investment areas that offer attractive prospects include
certain biotechnology companies (Portfolio holdings include Creative
Biomolecules, Cell Genesys, TheraTech, and PathoGenesis); the deregulation of
electric utilities; and new consumer-electronic technologies such as digital
television, the convergence of TV and personal computers, and digital versatile
discs.

SUMMARY

When we wrote to you six months ago, the Portfolio's stocks were selling at a
relatively attractive price/earnings (P/E) ratio of about 20, based on
most-recent earnings. We estimated that earnings on these stocks would grow at
a 23% annual rate. Today's stocks in the Portfolio have reported earnings
growth exceeding 30% and as a group are selling at prices equaling about 27
times earnings.  Whereas a P/E  of 27 is relatively high, it is similar to that
of the Russell 2000. We forecast earnings for our companies to grow by 27% next
year, compared with a growth rate of 24% for the companies in the Russell 2000
Index.

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved
by emphasizing stocks of small and emerging companies (market capitalizations
of $100 million to $500 million) with favorable prospects for price
appreciation. While most of the companies have records of growth and strong
market positions, the Portfolio also invests in companies that are pioneering
new technologies or appear to be undervalued.

REPORT FROM SCHRODER CAPITAL MANAGEMENT INTERNATIONAL
International Portfolio


The International Portfolio provided a total return of 18.6% during fiscal
1997, which ended on September 30. This exceeded the 12.5% return of the MSCI
EAFE Index and was in line with the 18.4% return on the average international
equity fund.

     Diversified portfolios invariably contain both good and relatively bad
news. The extremes of good and bad were more extreme than usual in fiscal 1997.
Continental European currencies fell, on average, by some 13% against the U.S.
dollar during the year, but European equity markets soared by more than 50% in
local-currency terms. The U.K. market rose by "only" 35% in local terms, but
the pound sterling rose 3% against the dollar. The Japanese market appeared to
break the mold, as its market fell 9% in yen terms even though the yen declined
by 8% versus the dollar. But the Japanese stocks in the Portfolio followed the
European pattern, rising nearly 20% in yen terms as the currency weakened. In
the developed Southeast Asia countries, Hong Kong was up more than 20%, while
Malaysia fell by roughly 45% in dollar terms. Among emerging markets, those in
Latin America rose by more than 50% while Asia's fell by more than 15%.

     Some of these contrasts look self-explanatory: Continental European
markets rose, in part, because their currencies were weak, and the U.K. market
would have risen by more had the pound sterling's strength not damaged the
profits of exporting companies. In Japan, some of our stocks' good performance
was due to the boost to companies' profits caused by the weak yen. However, in
the rest of Asia and in Latin America, stock markets simply reflected--and in
some cases exaggerated--varied local economic conditions.

     Markets usually perform best when there is spare capacity in the economy
and growth is just beginning to pick up. This was the case in many continental
European countries last year, with the Netherlands among those leading the
procession and Germany, Switzerland, and France trailing it. The German, Swiss,
and French economies are still in the early stages of recovery, which suggests
that their markets have strong reasons to rise further. But any ascent will
have to surmount "walls of fear"  because stock prices have risen dramatically
over the past two years. I have begun to take some profits, but have done so
selectively because many of the companies in the Portfolio are restructuring
and we believe that their results for at least the next two years will provide
more-than-adequate support for their share prices.

     The United Kingdom, like the United States, is at a more advanced stage in
the economic cycle; monetary policy has already been tightened to dampen
growth, and we expect that it will be tightened further over the next six
months. Although U.K. stocks are among the cheapest in Europe, there will prove
to be good reason for this if monetary policy is tightened further. The
Portfolio's exposure to the United Kingdom, at 9.1%, is the lowest it has been
in many years.

     During the past few months we began to look for opportunities to add to
our holdings in Asia--first in Japan, then in Hong Kong, and, most recently in
the smaller countries. Investors currently have very modest expectations for
Japan, and the market would be very





                                       18
<PAGE>   21
receptive to positive surprises. The best surprise would be signs that Japanese
consumers were ready to increase spending, but tax increases there in April
diminished disposable income, and the employment outlook is not yet encouraging
enough to prompt people to spend more and save less. Foreign trade remains
strong and so does investment spending by companies, but these factors have yet
to boost consumer confidence.

     The obverse of a dull jobs environment is continued cost-cutting by
Japanese companies, particularly those that compete globally. These are
predominant in our Portfolio, and their continued successes have produced
strong performance for us, as mentioned earlier. Indeed, the balance sheets of
companies in the Portfolio are flush with cash, and we are aware that the
emergence of share buybacks would provide a considerable further stimulus to
these stocks' prices. Buybacks are practicable under newly changed Japanese tax
law, but we do not expect companies to move rapidly in this direction. The
emergence of executive stock-option schemes helps by making Japanese companies
more conscious of boosting shareholder value, but this too will only slowly
grow in popularity.

     We increased exposure to Hong Kong because we anticipated a successful
handover of the territory to China, and we take an increasingly positive view
of economic developments there. The recent currency turmoil in southern Asia
has affected sentiment in Hong Kong's stock market but should not materially
affect developments in China or Hong Kong. Malaysia and the smaller emerging
markets in Asia have suffered a massive setback as a result of a loss of
confidence in their currencies. We have negligible exposure to Thailand, the
epicenter of the problems, but have  been taken aback by the spread of the
currency difficulties to the sounder economies of Indonesia and the
Philippines. That said, these markets have fallen sharply in U.S. dollar terms,
and many industrial and commercial stocks will be well placed to recover
strongly; banks, on the other hand, remain vulnerable to bad-debt problems
resulting from the crisis. We have negligible exposure to banks in the area.

     By contrast to Southeast Asia, Latin American markets have been very
strong and have provided the highest return to the Portfolio of any region in
fiscal 1997. We continue to limit our holdings in emerging markets. The past
year provides ample proof of the riskiness of individual markets and of the
benefits of diversification.

INVESTMENT PHILOSOPHY

The adviser believes that an international stock portfolio can achieve superior
long-term investment results by holding the stocks of non-U.S. companies with
the potential for above-average earnings growth.  Particular emphasis is placed
on companies in countries with favorable business and market environments.

</TABLE>


AVERAGE COUPON. The average interest rate paid on the securities held by a
portfolio. It is expressed as a percentage of face value.

AVERAGE DURATION. An estimate of how much a bond portfolio's share price will
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 a 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 A-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--after
adjusting for cash held as collateral for futures contracts.





                                       20
<PAGE>   23
COUNTRY DIVERSIFICATION. The percentages of a portfolio's common stock invested
in securities of various countries.

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 ISSUER. A breakdown of a portfolio's holdings by type of issuer
or type of instrument.

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.

EARNINGS GROWTH RATE. The average annual rate of growth in earnings over the
past five years for the stocks now in a portfolio.

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.

FOREIGN HOLDINGS. The percentage of a portfolio's net assets represented by
stocks or American Depository Receipts of companies based outside the United
States.

INVESTMENT FOCUS. This grid indicates the focus of a portfolio in terms of two
attributes. For equity portfolios, the attributes are market capitalization
(large, medium, or small) and relative valuation (growth, value, or a blend).
For fixed-income portfolios, the attributes are average maturity (short, medium,
or long) and average credit quality (high, medium, or low).

MEDIAN MARKET CAP. The midpoint of market capitalization (market price x shares
outstanding) of the stocks in a portfolio. Half the stocks in the portfolio have
higher market capitalizations and half lower.

PORTFOLIO ASSET ALLOCATION. This chart shows the proportions of a portfolio's
holdings allocated to different types of assets.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a portfolio, the weighted average price/book ratio of the
stocks it holds.

PRICE/EARNINGS RATIO. The ratio of a stock's current price to its per-share
earnings over the past year. For a portfolio, the weighted average P/E of the
stocks it holds. P/E is an indicator of market expectations about corporate
prospects; the higher the P/E, the greater the expectations for a company's
future growth.

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.

RETURN ON EQUITY. The annual average rate of return generated by a company
during the past five years for each dollar of shareholder's equity (net income
divided by shareholder's equity). For a portfolio, the weighted average return
on equity for the companies whose stocks it holds.

SECTOR DIVERSIFICATION. The percentages of a portfolio's common stocks that come
from each of the major industry groups that compose the stock market.

TURNOVER RATE. An indication of trading activity during the past year.
Portfolios with high turnover rates incur higher transaction costs and are more
likely to distribute capital gains (which are taxable to investors).

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

PERFORMANCE SUMMARY
Money Market Portfolio



All of the data on this page represent past performance, which cannot be used to
predict future returns that may be achieved by the Portfolio. 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 per share.

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 Money Market,
High-Grade Bond, and High Yield Bond Portfolios distribute their 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
other Portfolios' amounts of Distributions--Net Investment Income, and all
Portfolios' amounts of Distributions--Realized Capital Gain, may not match the
amounts 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
income was earned or 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, as well
as 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; and how much it costs
to operate the Portfolio.

        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. Finally, the table lists the Portfolio's Average
Commission Rate Paid, a disclosure required by the SEC beginning in 1996 for
Portfolios that invest in equity securities. This rate is calculated by
dividing total commissions paid on portfolio securities by the total number of
shares purchased and sold on which commissions were charged.

NOTES TO FINANCIAL STATEMENTS

Vanguard Variable Insurance Fund is registered under the Investment Company Act
of 1940 as a diversified open-end investment company and comprises the Money
Market, High-Grade Bond, High Yield Bond, Balanced, Equity Index, Equity Income,
Growth, Small Company Growth, and International Portfolios.

      Certain investments of the Money Market, High-Grade Bond, High Yield Bond,
and Balanced Portfolios are in corporate debt instruments; the issuers'
abilities to meet their obligations may be affected by economic developments in
their respective industries. The International Portfolio invests in securities
of foreign issuers, which may subject the Portfolio to investment risks not
normally associated with investing in securities of U.S. corporations.

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:
Common stocks listed on U.S. exchanges are valued at the latest quoted sales
prices as of the close of trading on the New York Stock Exchange (generally 4:00
p.m. Eastern time) on the valuation date; such securities not traded on the
valuation date are valued at the mean of the latest quoted bid and asked prices.
Securities listed on foreign exchanges are valued at the latest quoted sales
prices. Securities not listed on an exchange are valued at the latest quoted bid
prices. 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. FOREIGN CURRENCY: Securities and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars at the bid
prices of those currencies against U.S. dollars last quoted by major banks as of
5:00 p.m. Geneva time on the valuation date.

      Realized gains (losses) and unrealized appreciation (depreciation) on
investment securities include the effects of changes in exchange rates since the
securities were purchased, combined with the effects of changes in security
prices. Fluctuations in the value of other assets and liabilities resulting from
changes in exchange rates are recorded as unrealized foreign currency gains
(losses) until the asset or liability is settled in cash, when they are recorded
as realized foreign currency gains (losses).

      3. FUTURES AND FORWARD CURRENCY CONTRACTS: The Equity Index Portfolio uses
S&P 500 Index futures contracts to a limited extent, with the objectives of
maintaining full exposure to the stock market, enhancing returns, maintaining
liquidity, and minimizing transaction costs. The Portfolio may purchase futures
contracts to immediately invest incoming cash in the market, or sell futures in
response to cash outflows, thereby simulating a fully invested position in the
underlying index while maintaining a cash balance for liquidity. The Portfolio
may seek to enhance returns by using futures contracts instead of the underlying
securities when futures are believed to be priced more attractively than the
underlying securities. The primary risks associated with the use of futures
contracts are imperfect correlation between changes in market values of stocks
held by the Portfolio and the prices of futures contracts, and the possibility
of an illiquid market.

      The International Portfolio enters into forward currency contracts to
protect the value of securities and related receivables and payables against
changes in foreign exchange rates. The Portfolio's risks in using these
contracts include movement in the values of the foreign currencies relative to
the U.S. dollar and the ability of the counterparties to fulfill their
obligations under the contracts.

      Futures and forward currency contracts are valued at their quoted daily
settlement prices. The aggregate principal amounts of the contracts are not
recorded in the financial statements. Fluctuations in the value of the 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 gains (losses) on
futures or forward currency contracts.

                                       53
<PAGE>   56

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

      5. EQUALIZATION: Prior to October 1996, the Balanced and Equity Income
Portfolios followed the accounting practice known as "equalization," under which
a portion of the price of capital shares issued and redeemed, equivalent to
undistributed net investment income per share on the date of the transaction,
was credited or charged to undistributed income. As a result, undistributed
income per share was unaffected by capital share transactions. As of October 1,
1996, the Portfolios have discontinued equalization accounting and have
reclassified accumulated net equalization credits of $2,211,000 and $607,000,
respectively, from undistributed net investment income to paid in capital. These
reclassifications have no effect on the Portfolios' net assets, results of
operations, or net asset values per share.

      6. REPURCHASE AGREEMENTS: The Money Market Portfolio may invest in
repurchase agreements secured by U.S. government obligations. The other
Portfolios, along with other members of The Vanguard Group, transfer uninvested
cash balances to a Pooled Cash Account, which is invested in repurchase
agreements secured by U.S. government securities.

      Securities pledged as collateral for repurchase agreements are held by a
custodian bank until the agreements mature. Each agreement requires that the
market value of the collateral be sufficient to cover payments of interest and
principal; however, in the event of default or bankruptcy by the other party to
the agreement, retention of the collateral may be subject to legal proceedings.

      7. DISTRIBUTIONS: Distributions of net investment income to shareholders
of the Money Market, High-Grade Bond, and High Yield Bond Portfolios are
declared daily and paid on the first business day of the following month. Annual
distributions of net investment income to shareholders of the Balanced, Equity
Index, Equity Income, Growth, Small Company Growth, and International Portfolios
are recorded on the ex-dividend date. Annual distributions from realized capital
gains, if any, are recorded on the ex-dividend date.

      8. OTHER: Dividend income is recorded on the ex-dividend date. Security
transactions are accounted for on the date the 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 discounts on
debt securities purchased are amortized and accreted, respectively, to interest
income over the lives of the securities.

B.    The Vanguard Group furnishes investment advisory services to the Money
Market, High-Grade Bond, and Equity Index Portfolios on an at-cost basis.

      Wellington Management Company, LLP; Newell Associates; and Lincoln Capital
Management Company provide investment advisory services to the High Yield Bond,
Equity Income, and Growth Portfolios, respectively. For the year ended September
30, 1997, the investment advisory fees of the High Yield Bond, Equity Income,
and Growth Portfolios represented effective annual rates of 0.06%, 0.10%, and
0.15%, respectively, of average net assets.

      Wellington Management Company, LLP provides investment advisory services
to the Balanced Portfolio for a fee calculated at an annual percentage rate of
average net assets. The basic fee is subject to quarterly adjustments based on
performance relative to a combined index composed of the S&P 500 Index and the
Lehman Long-Term Corporate AA or Better Bond Index. For the year ended September
30, 1997, the investment advisory fee represented an effective annual basic rate
of 0.10% of the Portfolio's average net assets before a decrease of $6,000 based
on performance.

      Schroder Capital Management International Inc. provides investment
advisory services to the International Portfolio for a fee calculated at an
annual percentage rate of average net assets. The basic fee is subject to
quarterly adjustments based on performance relative to the Morgan Stanley
Capital International Europe, Australasia, Far East Index. For the year ended
September 30, 1997, the investment advisory fee represented an effective annual
basic rate of 0.13% of the Portfolio's average net assets before an increase of
$60,000 (0.03%) based on performance.

      Granahan Investment Management, Inc., provides investment advisory
services to the Small Company Growth Portfolio for a fee calculated at an annual
percentage rate of average net assets. 

                                       54


<PAGE>   57


The basic fee is subject to quarterly adjustments based on performance relative
to the Russell 2000 Index. For the year ended September 30, 1997, the investment
advisory fee represented an effective annual basic rate of 0.15% of the
Portfolio's average net assets before a decrease of $22,000 (an annual rate of
0.03%) based on performance.

C.    The Vanguard Group furnishes at cost corporate management, administrative,
marketing, and distribution services. The costs of such services are allocated
to the Fund under methods approved by the Board of Trustees. At September 30,
1997, the Fund had contributed capital aggregating $196,000 to Vanguard
(included in Other Assets), representing 1.0% of Vanguard's capitalization. The
Fund's Trustees and officers are also Directors and officers of Vanguard.

      Vanguard has asked the Fund's investment advisers to direct certain
portfolio trades, subject to obtaining the best price and execution, to brokers
who have agreed to rebate to the Fund part of the commission generated; such
rebates are used solely to reduce the Fund's administrative expenses. For the
year ended September 30, 1997, these arrangements reduced the expenses of the
Balanced Portfolio by $37,000 (0.01% of average net assets).

D.    During the year ended September 30, 1997, purchases and sales of 
investment securities other than temporary cash investments were:

      Balanced and Equity Income Portfolios' gains of $2,143,000 and $363,000,
respectively, on securities held for less than one year are treated as ordinary
income for tax purposes and will be included in income dividends to
shareholders; accordingly, such gains have been reclassified from accumulated
net realized gains to undistributed net investment income.

      During the year ended September 30, 1997, the International Portfolio
realized net foreign currency losses of $24,000, which decreased distributable
net income for tax purposes; accordingly, such losses have been reclassified
from accumulated net realized gains to undistributed net investment income.

E.    At September 30, 1997, net unrealized appreciation of investment 
securities for financial reporting and federal income tax purposes was:

VANGUARD VARIABLE INSURANCE FUND
FINANCIAL STATEMENTS
September 30, 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, which begin on page 40 of the accompanying report.

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each Portfolio's holdings, including
each security's market value on the last day of the reporting period. Securities
are grouped and subtotaled by asset type (common stocks, U.S. government and
agency issues, corporate bonds, etc.) and by industry sector or, for
international securities, by country. (The Equity Index Portfolio's S&P 500
Index securities are listed in descending market value order.) Other assets are
added to, and liabilities are subtracted from, the value of Total Investments 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. The NAV is the price used for Portfolio share
transactions with separate accounts of insurance companies, and differs from the
accumulated value of units in their variable annuity plans or variable life
insurance contracts.

      At the end of the Statement of Net Assets, you will find a table
displaying the composition of the Portfolio's net assets on both a dollar and
per-share basis. Because all income and any realized gains must be distributed
to shareholders each year, the bulk of net assets consists of Paid in Capital
(money invested by shareholders). The amounts shown for Undistributed Net
Investment Income and Accumulated Net Realized Gains usually approximate the
sums the Portfolio had available to distribute to shareholders as income
dividends or capital gains as of the statement date; Portfolios which distribute
net income to shareholders as a dividend each day usually have no Undistributed
Net Income. Any Accumulated Net Realized Losses, and any cumulative excess of
distributions over net income or net realized gains, will appear as negative
balances. Unrealized Appreciation (Depreciation) is the difference between the
market 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 Trustees of
Vanguard Variable Insurance 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 Vanguard Variable Insurance Fund 1997 Annual Report
present fairly, in all material respects, the financial position of Money Market
Portfolio, High-Grade Bond Portfolio, High Yield Bond Portfolio, Balanced
Portfolio, Equity Index Portfolio, Equity Income Portfolio, Growth Portfolio,
Small Company Growth Portfolio and International Portfolio (separate portfolios
of Vanguard Variable Insurance Fund, hereafter referred to as the "Fund") at
September 30, 1997, the results of each of their operations for the year then
ended and the changes in each of their net assets and the financial highlights
for each of the periods indicated, 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 September 30, 1997 by correspondence with the
custodian and the application of alternative auditing procedures where
securities purchased had not been settled, provide a reasonable basis for the
opinion expressed above.
