AT VANGUARD, WE BELIEVE
THAT TRADITION MATTERS

Our 8,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients. Our report cover pays homage to three anniversaries,
each of great significance to The Vanguard Group:

- - The 200th anniversary of the Battle of the Nile, which commenced on August 1,
  1798. HMS Vanguard, the victorious British flagship at the Nile, is our
  namesake. And its motto-- "Leading the way"--serves as a guiding principle
  for our company.

- - The 100th birthday, on July 23, 1998, of Walter L. Morgan, founder of
  Wellington Fund, the oldest member of what became The Vanguard Group. Mr.
  Morgan was friend and mentor to Vanguard founder John C. Bogle, and helped to
  shape the standards and business principles that Mr. Bogle laid down for
  Vanguard at its beginning nearly 25 years ago: a stress on balanced,
  diversified investments; insistence on fair dealing and candor with clients;
  and a focus on long-term investing. To our great regret, Mr. Morgan died on
  September 2, 1998.

- - The 70th anniversary, on December 28, 1998, of the incorporation of Vanguard
  Wellington Fund. It is the nation's oldest balanced mutual fund, and one of
  only a handful of funds created in the 1920s that are still in operation.

Although Vanguard constantly tackles new challenges, adopts new technology, and
develops new services, we treasure the traditions and values that set us apart
in a crowded, competitive industry. And we salute our shareholders, whose
support and trust we strive to earn each and every day.

DEAR SHAREHOLDER,

[PHOTO]

During the first six months of Vanguard Variable Insurance Fund's 1999 fiscal
year, U.S. and international stocks rose while long-term bond prices fell as
interest rates climbed.

    For the six months ended March 31, 1999, the returns of our portfolios
varied considerably, ranging from a spectacular +29.8% for our Growth Portfolio
to a lackluster -0.1% for our High-Grade Bond Portfolio. Just as our absolute
performances were mixed, so too were our results relative to similar mutual
funds. Of the nine portfolios in existence during the entire six months, five
outpaced their average peers, while four fell short.

    Throughout this report we present the six-month total returns (capital
change plus reinvested dividends) for our portfolios, along with the results of
their average comparative standards. 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 return
into its income and capital components, are presented on pages 19-24. We point
out that the returns for the portfolios of the Vanguard Variable Insurance Fund
are higher than those of the portfolios in the Vanguard Variable Annuity Plan,
which take into account the administrative and insurance expenses associated
with the plan.

    We also present the initial results of the four portfolios that we
introduced to the Vanguard Variable Insurance Fund lineup in February: the
Short-Term Corporate, Diversified Value, Mid-Cap Index, and REIT Index
Portfolios.

THE PERIOD IN REVIEW

During the six months ended March 31, the U.S. stock market rebounded in a big
way from 1998's midyear slump, when most benchmarks declined -20% or more. The
entire U.S. stock market, as measured by the Wilshire 5000 Equity Index, rose
+26.1% during the first half of our fiscal year, setting record highs along the
way. Large-capitalization stocks, as measured by the Standard & Poor's 500
Composite Stock Price Index, were up even more strongly, at +27.3%. Meanwhile,
the Russell 2000 Index of small-cap stocks gained +10.0%, a six-month
performance that was superb by historical standards but subpar in comparison
with larger stocks.

    The stock market's gains were far from evenly distributed. The return for
the growth stocks within the S&P 500 Index was an amazing +33.1%, compared with
+20.8% for the value stocks. Among smaller stocks, the growth/value split was
even more striking: a +21.6% return for growth issues versus a decline of -1.5%
for value stocks.

    The stock market's generally strong performance came despite two factors
that might have daunted investors: First, corporate earnings declined slightly
in 1998 and were expected to rise less than 3% during early 1999. Second,
interest rates rose, which often is a negative signal for stocks. The rise was
steeper for securities with longer maturities. The yield of the benchmark
30-year U.S. Treasury bond rose 65 basis points (0.65 percentage point), from
4.98% when the fiscal year began to 5.63% as of March 31. At the shorter end of
the spectrum, the yield of 3-month Treasury bills rose 12 basis points to
4.48%. Bond prices, which move in the opposite direction from interest rates,
declined during the half-year, subtracting -3.2% from the return of the Lehman
Brothers

                                       1

Aggregate Bond Index, a proxy for the taxable bond market. This price
decline more than offset interest income, resulting in a -0.2% total return for
the index. Generally, the interest rate increase was caused by fear that
inflation cannot remain dormant forever, together with signs that the global
economic crisis is easing. Both factors cooled interest in Treasury securities
over the past several months.

    On the international scene, results from European markets were excellent,
but returns from the Pacific region and the emerging markets were better still.
Europe's return of +16.3% in U.S. dollars during the six months--a terrific
half-year return--paled in comparison with the +40.1% return (in U.S. dollars)
from the Pacific region and the +30.5% return (also in dollars) from the
emerging markets. Generally, the returns from the Pacific region and emerging
markets represented rebounds from lows hit last fall during the global economic
crisis. Overall, solid returns from the Pacific and emerging markets were
augmented by a decline in the value of the U.S. dollar versus other currencies,
particularly the Japanese yen. In Europe, the dollar generally strengthened,
diminishing returns for U.S. investors in those markets. A summary of the
half-year results of each of our portfolios follows.

FIXED-INCOME PORTFOLIOS

The MONEY MARKET PORTFOLIO earned +2.5% during the six months, ahead of the
+2.2% return of the average money market mutual fund. Short-term interest rates
rose slightly during the period. At the beginning of the half-year on October 1,
the yield of the 3-month T-bill stood at a twelve-month low of 4.36%, but by
March 31 had edged up to 4.48%. Our performance margin over our average peer
essentially comes down to cost. Our annualized expense ratio (expenses as a
percentage of average net assets) is 0.21%, or $2.10 per $1,000 invested--far
below the 0.82%, or $8.20 per $1,000, charged by the average money market mutual
fund.

 it is possible to lose money by investing in the portfolio.

    Our HIGH-GRADE BOND PORTFOLIO provided the lowest return of the nine
portfolios in existence during the entire half-year. Its return of -0.1% was
slightly better than the -0.9% return of its average peer. The prices of our
bonds declined because of higher interest rates, more than offsetting the
interest income earned during the period. Our return was a bit better than the
- -0.2% return of our target Lehman Aggregate Bond Index.

    The HIGH YIELD BOND PORTFOLIO'S six-month return of +4.6% measured up well
versus its unmanaged index but fell short of the +5.7% return of the
portfolio's average competitor. Our shortfall versus our peers owed to our more
conservative stance of holding higher-quality--and thus less-risky--securities.
Investors willing to accept the higher risk of lower-quality bonds in exchange
for higher interest income were rewarded during the six months, when strong
economic growth increased the likelihood that borrowers would be able to repay
their debts.

BALANCED PORTFOLIO

Our BALANCED PORTFOLIO earned a +7.4% return during the six months, reflecting
both the excellent gains by large-cap stocks and the negative returns from
long-term bonds. Our return fell well short of the +12.6% return of the average
balanced fund and was less than half the +16.4% return of our unmanaged
benchmark--a composite index weighted 65% in the S&P 500 Index and 35% in
high-quality, long-term bonds. Our shortfall can be largely explained by two
factors: our emphasis on value stocks, which significantly underperformed
growth stocks during the half-year, and our focus on longer-term bonds, which
suffered most from the increase in interest rates.

DOMESTIC EQUITY PORTFOLIOS

The +10.8% return of our EQUITY INCOME PORTFOLIO, while solid on an absolute
basis, was subpar in comparison with our average peer and the powerful S&P 500
Index. The high-yielding stocks we emphasize trailed growth stocks badly during
the six months. The portfolio was significantly underweighted in the
half-year's two best-performing sectors: technology and consumer discretionary
(mainly retailers). Many stocks in these groups don't fit our investment
criteria because their dividend payments are low or nonexistent. Also, we
maintained our customary heavy commitment to the utilities sector (about 26% for
our portfolio during the six months versus 12% for the index) because of the
attractive dividend income those stocks typically provide. However, the utility
group's biggest gains came from telecommunications equipment stocks, many of
which pay little or no dividends and therefore do not fit the profile for stocks
we seek.

</TABLE>

    The EQUITY INDEX PORTFOLIO provided a stupendous return of +27.5% for the
half-year, outpacing the average general equity mutual fund by 5.8 percentage
points and even besting the +27.3% return of the unmanaged S&P 500 Index. Our
significant margin over our average peer was primarily the result of the
market's extreme bias toward stocks of large companies. Our performance
advantage over the S&P 500 is a notable feat because the index exists only "on
paper" and bears none of the operating expenses or transaction costs incurred by
actual investment portfolios. Our low expense ratio, which at 0.19% of average
net assets is more than a full percentage point lower than that of our average
peer, helps us to closely track the index and provides a significant head start
versus competing funds.

    Stocks of large growth companies continued to soar during the half-year, and
our GROWTH PORTFOLIO participated in the rise. Our six-month return of +29.8%
topped both

                                       3

<PAGE>   6


the +28.2% return of the average growth mutual fund and the +27.3% return of
the S&P 500 Index. However, we fell short of the +33.1% return of the S&P 500
Index's growth component, which is a good measure of the large-cap growth
stocks we emphasize. Earning a six-month return that nearly equals three years'
worth of "normal" stock market gains is quite an accomplishment, but one that
is not likely to be repeated often.

    During a six-month period when small stocks were left in the dust by large
stocks, our SMALL COMPANY GROWTH PORTFOLIO turned in a solid performance, both
on an absolute basis and relative to its peer mutual funds. Our +14.4% return
was 1.3 percentage points higher than the return of the average small company
growth fund and 2.7 percentage points ahead of the +11.7% return of the Small
Company Growth Fund Index, an unmanaged index we use to evaluate our
performance.

INTERNATIONAL PORTFOLIO

Our INTERNATIONAL PORTFOLIO provided a solid return of +16.7% for the
half-year, but one that was somewhat disappointing relative to its comparative
standards. Our return was 1.5 percentage points below the +18.2% return of the
average international mutual fund and nearly six percentage points lower than
the +22.5% return of the Morgan Stanley Capital International Europe,
Australasia, Far East (EAFE) Index. Gen-erally, our relative performance was
hindered by our bigger stake in Europe, which lagged Asia and the emerging
markets. Both of these markets turned in excellent performances for the six
months, rebounding from lows reached last summer after big declines in 1997 and
early 1998.

OUR NEW PORTFOLIOS

Our four new portfolios, which fill several niches in our lineup, began
investment operations in early February. For the record, we present their
performance during their first seven weeks of existence. But we emphasize that
results over such a brief period are hardly meaningful. Any long-term
investment, particularly that of a variable insurance contract, must be judged
over periods of years and decades, not days, weeks, or even months. We are
confident that over long periods, the results of our funds will be fully
competitive with those of similar investments. A big reason for our confidence
is the simple fact that our much lower operating expenses give us a weighty
advantage over our competitors, year after year.

IN SUMMARY

As the returns from the financial markets demonstrated during the past six
months, unpredictability is a hallmark of investing--especially over short time
periods. Because

the market's leaders and laggards will trade places time and again, we believe
a balanced approach to investing is the prudent way to reap the rewards of the
financial markets while helping to limit some of the risks.

    The low-cost portfolios of Vanguard Variable Insurance Fund provide an
excellent opportunity to create a diversified investment program through a
tax-advantaged variable annuity or variable life insurance plan. Such a
balanced program helps investors to "stay the course" through the markets' ups
and downs by combating the tendency to become overly optimistic during upturns
or overly pessimistic during downturns. In short, our counsel is to have a plan
and stick with it.

    We look forward to reporting to you on the full fiscal year six months
hence.

THE MARKETS IN PERSPECTIVE

SIX MONTHS ENDED MARCH 31, 1999

Stock markets worldwide provided solid gains during the six months ended March
31, 1999, as they recovered from a sharp slide in midsummer 1998. Central banks
around the world helped by easing monetary policy and lowering short-term
interest rates.

    A remarkably robust performance by the U.S. economy was a key factor in the
global recovery. Indeed, the United States was the only major economy in which
policymakers and bondholders had to ponder whether growth was too rapid.
Concern about a potential inflationary surge was one reason that longer-term
interest rates rose modestly and bond prices generally slipped in the United
States.

U.S. STOCK MARKETS

The surge in U.S. stocks during the half-year reflected both the strength of
the domestic economy and the confidence of investors in future corporate and
economic prospects. The overall market, as measured by the Wilshire 5000 Equity
Index, gained 26.1%. The S&P 500 Index, which is dominated by
large-capitalization stocks, advanced 27.3%. Small-cap stocks, which have
consistently underperformed large-cap stocks in recent years, gained 10.0%, as
measured by the Russell 2000 index.

    There was also a striking disparity in returns from growth and value
stocks; the growth-stock segment of the S&P 500 Index gained 33.1%, while the
value-stock segment rose 20.8%.

*Annualized.

    Investors in U.S. stocks seemed to have forgotten the jitters that sent
market indexes plummeting by 20% or more during the summer of 1998. Nor did
they appear to care that corporate earnings were flat to slightly lower during
the half-year. Investors focused more on the potential for future earnings than
on near-term disappointments. Interest rate reductions by central banks,
including three separate quarter-percentage-point cuts during autumn 1998 by
the U.S. Federal Reserve Board, lessened fears that the major economies would
be dragged down by the economic and currency troubles still afflicting much of
Asia, Russia, and Latin America. There was certainly little fear among U.S.
consumers, who were encouraged by low unemployment, rising wages, and low
inflation to spend freely. Their spending propelled the economy to a 6%
annualized growth rate during the first quarter of our fiscal year.

                                       6
<PAGE>   9

    With consumer spending so strong, it is no surprise that retailers and
other companies in the consumer-discretionary sector were the stock market's
leaders during the fiscal half-year, rising 49% on average. Technology stocks
were a close second, gaining 48%. Optimism--some would say overoptimism--was
especially evident in Internet stocks.

    The market's laggards were energy stocks (integrated-oil companies were up
a relatively paltry 6%; "other energy" rose about 14%) and the consumer-staples
and materials & processing groups (each up about 10%). Energy stocks lagged
because prices for oil and natural gas were weak, despite upticks late in the
period. Several large makers of consumer staples, such as beverages and
tobacco, reported disappointing overseas profits.

U.S. BOND MARKETS

Early in the fiscal year, long-term interest rates fell to 30-year lows as a
result of the favorable inflationary environment and heavy demand from
investors who sought the perceived safety of U.S. Treasury bonds amid overseas
economic turmoil. The yield of the 30-year Treasury began the period at 4.98%
and fell to a low of 4.72% on October 5. However, as prices of stocks and
riskier bonds rebounded from their summertime lows, Treasury bond prices began
to fall and their yields began to rise. By March 31, the yield on the 30-year
Treasury was at 5.63%, up 65 basis points (0.65 percentage point) for the
half-year. The Lehman Brothers Long U.S. Treasury Bond Index declined -5.2%
during the half-year. The overall U.S. taxable bond market, as measured by the
Lehman Aggregate Bond Index, which has an intermediate-term average maturity,
had a negative return of -0.2%. High-yield bonds, which had suffered along with
other risky assets during last summer's slump in financial markets, produced
positive returns during the half-year.

    Short-term interest rates, which were most directly affected by the Federal
Reserve Board's reductions, rose only slightly. Yields on 3-month Treasury
bills began the half-year at 4.36% but fell as low as 3.62% in mid-October. By
March 31, the 3-month T-bill was yielding 4.48%, only 12 basis points higher
than the rate when the period began.

INTERNATIONAL STOCK MARKETS

International stock markets, heartened by Wall Street's strong rally and easier
monetary policy, rallied during the half-year. Overall, the Morgan Stanley
Capital International Europe, Australasia, Far East (EAFE) Index gained 22.5%
in U.S. dollars. The gains were due, in part, to interest rate cuts by monetary
authorities in Japan, Europe, and Latin America. Investors also were heartened
by an increase in corporate restructuring and merger activity in Europe and
recession-wracked Japan.

    The biggest gains overseas were for those bourses hit hardest during 1997
and 1998: emerging markets (the MSCI Select Emerging Markets Free Index rose
30.5% during the six months) and the Pacific region (up 40.1%). Further
boosting returns for U.S. investors was a weakening of the U.S. dollar against
the Japanese yen. In a turnabout, Europe's developed stock markets--which
account for some 70% of the EAFE Index--were the laggards, although they
performed well on balance, providing an aggregate return of 16.3% for U.S.
investors. While the U.S. dollar was weakening against the Japanese yen, and
thus boosting returns from the Pacific region for U.S. investors by more than
12 percentage points, it was gaining against most European currencies, cutting
U.S. investors' returns on European stocks by about 5 percentage points.

    In some emerging markets where stocks had plummeted in 1997 and 1998, the
six-month gains were spectacular: about 130% in U.S.-dollar terms in South
Korea, 115% in Indonesia, 69% in Malaysia, 66% in the Philippines, and 43% in
Mexico.

REPORT FROM VANGUARD
FIXED INCOME GROUP

MONEY MARKET, SHORT-TERM CORPORATE,
AND HIGH-GRADE BOND PORTFOLIOS

THE INVESTING ENVIRONMENT

The semiannual period ended March 31, 1999, will be remembered for its
roller-coaster qualities. Interest rates first experienced deep dips brought on
by the turmoil in Asia, Russia, and Brazil, as yields on long-term Treasury
securities dropped so far that they were half-a-percentage point below
short-term rates. Subsequently, as investors realized that the U.S. economy
remained on its growth track, long-term rates snapped back to where they
exceeded short-term rates by nearly 1 percentage point. So despite confronting
sharp curves, where we were uncertain what was around the bend (such as when
Russia defaulted on its debt), the market's thrill ride took us safely back to
where we began the period. The U.S. economy is still growing strongly, as the
gross domestic product expanded at an annual pace of 6% during the final
quarter of 1998 and the unemployment rate continued to shrink, ending the
half-year at 4.2%. Inflation remains subdued, allowing money market investors
to enjoy substantial real, or inflation-adjusted, returns.

    The period's volatile ride began with heightened concerns that
deteriorating financial conditions in Asia could trigger a global economic
slowdown. These concerns peaked when Russia devalued its currency and defaulted
on its debt, steps that sent investors around the globe scurrying for the "safe
haven" of U.S. Treasury securities. The desire to own Uncle Sam's debt was so
strong that corporate issuers faced a marketplace reluctant to purchase their
debt, which added to the instability and illiquidity in our markets. In
response to these destabilizing forces, the Federal Reserve Board lowered
interest rates on three occasions during autumn 1998, ultimately bringing the
federal funds rate down from 5.50% to 4.75%. The Fed's action helped restore
order in the financial markets, and by first-quarter 1999 the spreads between
yields on different types of fixed-income securities had returned to more
normal relationships.

    For most of the half-year, the yield curve for Treasury securities remained
relatively flat, indicating that market participants were inclined to believe
the Fed would lower interest rates further. The market remained focused on the
potential impact to our economy of the trouble overseas, until a string of
positive surprises in the number of new jobs reminded the

                                       8
<PAGE>   11


market that the U.S. economy had retained its forward momentum. Continued
strength in retail sales plus record-setting sales of new homes provided ample
evidence of the benefits to the economy of lower interest rates, higher wages,
and low inflation. The fears that the global crisis would severely crimp our
forward momentum never materialized. Neither did the anticipated damage to U.S.
companies from a flood of cheap overseas products from countries that had
devalued their currencies. Near the end of the six-month period, speculation
that the Fed would need to lower interest rates further to spur the economy
shifted to expectations that interest rates would need to be raised to restrain
the economy's expansion.

MONEY MARKET PORTFOLIO

The Money Market Portfolio earned a 2.5% return during the half-year,
surpassing the 2.2% return of our average peer. In managing the portfolio, we
maintained a longer-than-usual average maturity, a stance that allowed us to
capture yields that reflected the market's expectations of higher interest
rates in the future. We expect the Fed to maintain short-term interest rates at
their present level for the near term. We continue our long-standing practice
of investing only in issues with high credit quality. Because our portfolio's
expense ratio is significantly lower than that of the average money market
mutual fund, we are able to achieve superior investment returns while
maintaining high quality standards.

SHORT-TERM CORPORATE PORTFOLIO

After less than two months of operations--the portfolio commenced investing on
February 8--there is little to say about the performance of the portfolio. For
the record, it earned 0.2%, a fraction above the return of the average
short-term corporate bond fund. Although interest rates and bond returns will
fluctuate from period to period, investors in the portfolio can count on
stability in terms of our management of their assets. We will invest in
high-quality corporate securities and maintain an average weighted maturity
within a range of 1 to 3 years. When we believe we can add value, we will
adjust the maturity of the portfolio's holdings within that range. Also, we
constantly analyze the relative values of individual securities and sectors
within the fixed-income market, and will emphasize those that appear to us to
offer good value.

HIGH-GRADE BOND PORTFOLIO

As you know, 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 March 31, 1999, the portfolio's total returns were -0.1% and 6.5%,
respectively, compared with the index's posted returns of -0.2% and 6.5%. When
the fund's returns are adjusted for expenses and transaction costs (neither of
which affects the index), the fund outpaced the index by 0.3 percentage point
for the half-year and 0.5 percentage point for the 12 months ended March 31.
Our total return for the half-year was 0.8 percentage point ahead of the
average fund in our peer group. The performance of the various sectors of the
Lehman Aggregate Bond Index for the 6- and 12-month periods ended March 31,
1999, is shown at left.

    The best-performing category--by a significant margin--during the period
was the mortgage sector. The higher yield and shorter average life of
mortgage-backed securities combined to protect this sector during this period
of rising interest rates. The spreads between yields of corporate bonds and
those of Treasury bonds narrowed as fears about the global financial and
economic crisis eased. This resulted in corporate bonds outperforming
government bonds during the half-year, although over the last 12 months,
government bonds performed slightly better than corporate or mortgage-backed
securities.

    As of March 31, the portfolio comprised 26% government bonds, 37% corporate
bonds, 4% foreign bonds (denominated in U.S. dollars), and 33% mortgage-backed
securities.

INVESTMENT PHILOSOPHIES
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.

SHORT-TERM CORPORATE
PORTFOLIO

The adviser believes a portfolio can provide relatively high levels of current
income with only modest share-price fluctuation by holding high-quality
corporate bonds with short- and intermediate-term maturities.

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

For the 6- and 12-month periods ended March 31, 1999, the High Yield Bond
Portfolio provided total returns of 4.6% and 2.8%, respectively.

    As we have noted before, the direction of interest rates--which is the
primary short-term driver of performance in the overall bond market--is not
always the determining factor in the behavior of the high-yield market. For
example, yields on 10-year U.S. Treasury securities rose 82 basis points
between September 30, 1998, and March 31, 1999, resulting in sharp price
declines for longer-term Treasuries (the Lehman Long U.S. Treasury Index had a
capital return of -8.1% and a total return of -5.2% for the six months).
However, high-yield bonds experienced, on average, only slight price declines
(the Lehman High Yield Index had a capital return of -0.6% and a positive total
return of 4.0% for the half-year).

    In short, the below-investment-grade, or high-yield, bond market continues
to be a hybrid one. Under some market conditions, it follows the direction of
the stock market; at other times, it behaves similarly to the bond market. When
the stock market is very volatile, as it has been during the past year or so,
below-investment-grade bonds usually perform in the same direction as stocks.
But when the stock and bond markets are reasonably stable, high-yield bonds
tend to trade more like investment-grade bonds.

    Currently, with concerns about an economic slowdown fading, together with
an easing in the "flight to quality" that occurred during summer 1998, the
high-yield market should perform well. Investors will increase their tolerance
for risk as companies' profits remain strong, issuers' ability to repay their
debts increases, and rating agencies upgrade their outlook for the individual
companies. The market still has not recovered completely from the turmoil that
affected global financial markets late last summer. Given that fears of a
credit contraction have receded, we are somewhat surprised that the risk
premium--the yield differential between high-yield bonds and bonds of higher
credit quality--is still so high.

    We remain very selective with respect to credit quality as we examine the
large number of new high-yield bond issues continuing to come to market. We are
avoiding the smaller start-up companies and continuing to emphasize the
higher-quality end of the spectrum of below-investment-grade bonds.

    We perform in-depth credit research on a company-by-company basis, and we
emphasize diversification. The portfolio owns issues representing a broad range
of industries and companies. Our holdings continue to be predominantly
cash-paying issues rated B or better.

Earl E. McEvoy, Senior Vice President
and Portfolio Manager

April 14, 1999

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 provided a return of 7.4% during the six months ended
March 31, 1999, versus 12.6% for the average balanced fund and 16.4% for our
composite stock/bond index, weighted 65% in the S&P 500 Index and 35% in
long-term, high-quality corporate bonds. The portfolio's stocks, representing
about 65% of assets as of March 31, appreciated 13.6%. The stock market gained
27.3% during this period, boosted by three successive reductions in short-term
interest rates by the Federal Reserve Board. Lower rates particularly benefit
growth stocks, which, led by the technology sector, did extremely well. Our
focus on companies with low price/earnings ratios and above-average dividends
hurt our relative performance. The portfolio's bond segment, representing about
35% of assets, declined -2.2% during the six-month period, as a result of
rising interest rates.

    We continued to make moderate changes to the equity holdings in the
portfolio, but maintained our emphasis on the financial-services, materials,
industrial, health-care, and energy sectors. The annualized dividend yield on
the portfolio's stocks was 2.3% as of March 31, compared with 1.3% for the S&P
500 Index. New names among our holdings during the last six months include
Delphi Automotive Systems, which was spun off by General Motors, and
Schlumberger, the leading oil-service company.

    The "value" orientation of the portfolio's stocks has been a handicap in
our relative performance in a market that has embraced a narrow group of
low-yielding growth stocks. We believe that world economic growth, which has
been held back by economic problems in Asia and South America, will recover
late in 1999 and that this will benefit the more cyclical value stocks that
traditionally make up a large part of our holdings.

    In the fixed-income portion of the portfolio, corporate bonds did well
relative to U.S. Treasury securities, which helped our performance. We saw a
partial reversal of the flight of investors to Treasury securities that
occurred in summer 1998, when Treasuries benefited from fears about the
financial situation in South America, Russia, and Asia. We do not expect
interest rates to decline from current levels, in view of the global economic
recovery that we anticipate.

    As of now, investors continue to favor a narrow group of growth stocks,
particularly those related to technology and telecommunications. We believe
that at some point other market sectors will more fully participate in the
market's advance, especially given an environment of stronger world economic
growth combined with stable interest rates. We believe your portfolio is well
positioned for such an outlook.

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

April 14, 1999

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 rose 10.8% during the six months ended March 31,
1999, well behind the 27.3% return of the S&P 500 Index. The important story
behind the market rise is not its strength but the degree to which
large-capitalization growth stocks outperformed other large companies.

    Some observers have noted that the superior performance of growth stocks
represents a major change in investor sentiment--that is, investors are
abandoning the search for good companies at attractive prices and are merely
chasing stocks with strong upward price momentum, regardless of valuation or
degree of risk. The fact that only a few large companies are driving the major
indexes magnifies the effect of this change, highlighting the market's apparent
casino mentality. One effect of this momentum-investing phenomenon is the
enormous spread during the past six months between the performance of the
technology-dominated S&P 500 Index and that of the average equity income fund,
which gained 13.2%.

    Value portfolios offered few bright spots during the period to counter the
blazing performance of tech companies. Drug stocks retained some excitement,
but outside of technology and a few other large growth stocks, investors had
little enthusiasm for the bulk of corporate America.

    The current bull market has long since shattered the historical limit of
every traditional measure of stock valuation, so there is no credible ceiling
on the extent of the excess this market could achieve. It takes only one
success, the story goes, to achieve instant wealth, just as it takes only one
winning lottery ticket to make up for all those that didn't win. In such an
environment, it is no wonder that some managers foresake fundamental analysis
and long-followed investment disciplines to simply follow fads.

    The problem with abandoning discipline is that investing is not just a
performance game for speculators, but serious work for millions of people whose
retirement years will be shaped by their investment efforts. For a retirement
system to work, it must not resemble a lottery, with a few big winners and lots
of losers; virtually everybody needs to be at least a modest winner. And for
that to happen, most investors must eschew the temptation to gamble on the big
win and must exercise prudence, settling for a more modest return in exchange
for lower risk.

    Judge Samuel Putnam, who authored the "prudent man rule" in a court opinion
in 1830, advised investors to exercise judgment and care "not in regard to
speculation but in regard to the permanent disposition of their funds,
considering the probable income as well as the probable safety of their
capital." His prescription may not get investors to their financial goals in
spectacular style, but it will move them steadily toward those ends with some
confidence that they will actually be achieved.

INVESTMENT PHILOSOPHY

The adviser believes that a portfolio made up of undervalued stocks, whose
dividend yields compared to the overall market are above-average, both
currently and in relation to historical norms, 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 BARROW, HANLEY,
MEWHINNEY & STRAUSS, INC.

DIVERSIFIED VALUE PORTFOLIO

The Dow Jones Industrial Average is above 10,000, as of this writing. Such a
level for the stock market was unimaginable ten years ago. We were propelled to
this lofty place by a robust economy (the strongest on earth), low interest
rates (the best since the 1960s), a federal budget surplus (the first
back-to-back surpluses since the 1950s), and low inflation.

    Cash flows into stocks have been very strong, in large measure due to
individual retirement accounts and other retirement-savings vehicles. So long
as corporate earnings are good, confidence in the economy and government is
high, and inflation is under control, prices can hold at current levels and
even improve.

    This is our first semiannual letter to investors in Vanguard Variable
Insurance Fund. As you know, the Diversified Value Portfolio has been in
operation for only a fraction of the semiannual period. In fact, the 51-day
period since the portfolio's inception (through March 31, l999) is so short
that investment returns are not very meaningful.

    We feel it's important for this letter to discuss what you can expect the
portfolio to look like in the future. Additional funds will generally be
invested in our existing holdings. We are value investors, and while most
organizations lay claim to that description, we believe that we are more
dedicated to its pursuit than many practitioners. We define value stocks as
those with low price/earnings and price/book ratios and high current dividend
yields. Most of the portfolio's individual stocks will have these
characteristics, and the portfolio as a whole certainly will have them. As a
guideline, expect the portfolio's average P/E ratio to be 70%-80% of the
average P/E of the S&P 500 Index. Likewise, the price/book ratio of our
holdings will be about 70% of the market average. And the current dividend
yield, before expenses, will be 140%-180% of the yield of the S&P 500.

    Investment turnover for the portfolio should average 25%-30% annually,
indicating that we will hold our average security for three to four years. No
individual stock should represent more than 5% of the portfolio's total assets.
We are not likely to have large cash reserves, since we do not hold ourselves
out as market-timers.

    We, like many professional investors, are concerned with the price level of
Internet stocks, and worry that the speculators driving up these stocks could
trigger a panic. While we are unlikely to invest in small initial public
offerings or stocks with no earnings, a sharp decline in those types of
securities could spill over into our investment arena and spoil the party. We
would hope the defensive nature of this portfolio would serve us well should
such an event occur, but it certainly would not make us immune to a general
market decline.

James P. Barrow

April 12, 1999

INVESTMENT PHILOSOPHY

The adviser believes that superior long-term investment results can be achieved
by holding a diversified portfolio of out-of-favor stocks that have
above-average dividend yields, below-average prices in relation to earnings,
sales, and book value, and the prospect of above-average total return.

REPORT FROM LINCOLN CAPITAL
MANAGEMENT COMPANY

GROWTH PORTFOLIO

The stock market sagged during the six months ended September 30, 1998. The
ensuing six months, were gangbusters, with the S&P 500 Index up 27.3%. It's
hard to remember another such dramatic turnaround.

    The Growth Portfolio's 29.8% return was a bit ahead of both the S&P 500 and
the average growth mutual fund (up 28.2%). However, it lagged by 3 to 5
percentage points representative large-capitalization growth stock indexes. We
trailed those indexes because we were underweighted in some of the technology
stocks that led the market's surge--including some of the largest tech stocks
and those associated with the Internet. The fact that your portfolio did not
own America Online and had some unproductive holdings in enterprise software
issues caused this sector of the portfolio to fall behind the indexes. This
six-month shortfall was sufficient to cause returns for the Growth Portfolio to
lag the large-cap growth indexes slightly over the one-, three- and five-year
periods ended March 31, although our returns still exceeded those of the S&P
500 Index and most growth mutual funds.

    Major portfolio purchases during the past six months were new positions in
IBM and Nokia, plus additions to our holdings of Merck, Intel, and Procter &
Gamble. Sales included elimination of our stakes in Compaq, Carnival, Lowe's,
and Household International (completed in early April) and a trimming of our
Microsoft position. The total number of issues held rose from 75 to 79. Our ten
largest holdings account for about 40% of assets. Three of the top ten are new
to the list: Lucent, Dell, and Bristol-Myers Squibb. Coca-Cola, Monsanto, and
Philip Morris dropped from the list. The main change in our industry weightings
was an increase in technology holdings, from 21% of assets to 26%, mostly as a
result of this group's superior performance. New purchases among tech stocks
reflect our view that the sector still possesses attractive longer-term
potential.

    During the period, our big winners were Microsoft, Cisco, General Electric,
Chase Manhattan, and Wal-Mart. Losers included Philip Morris and Monsanto.

    We thought you might like our opinion on the Internet. This has been an
extraordinarily productive area for investment in the past year or so,
especially for America Online, which is the largest-cap Internet firm and--you
may not believe it--the 13th-largest stock in the S&P 500 by market cap. We
have struggled with both valuations and business models in such a dynamic
environment. We don't view valuations of many Internet stocks as absurd. Their
high prices reflect expectations of very high growth and of limited
capital-spending needs after several years. We have underestimated these
evolving expectations for growth and capital productivity, and we'll continue
wrestling with this segment of the growth market.

David Fowler, Portfolio Manager
Parker Hall, Portfolio Manager

April 13, 1999

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.

SMALL COMPANY GROWTH PORTFOLIO

The Small Company Growth Portfolio generated a gain of 14.4% during the six
months ended March 31, 1999, a period that included a strong small-cap rally
near the end of 1998. In the final months of our fiscal half-year, however,
small-cap stocks, with some exceptions, reverted to underperforming larger
stocks. The portfolio's results for the six- and 12-month periods ended March 31
are shown to the left, along with results for our index benchmark.

</TABLE>

    During the half-year, positive contributions to our performance came from
holdings in the technology, consumer-discretionary, and health-care sectors,
which together accounted for more than half the portfolio's assets. Very strong
performers among our technology holdings included RealNetworks (Internet
streaming media for video and audio), BroadVision (website customer profiling),
and Exchange Applications (database analysis software). In the health-care
sector, good performers included Biogen (excellent results continue with Avonex
for treating multiple sclerosis), Genzyme, and Abgenix. Ames Department Stores
(we see large potential in its acquisition of Hills Stores) and CEC
Entertainment (an innovative restaurant chain with good margins) contributed
significantly in the consumer sector.

    Several holdings hurt our performance. In the financial-services group (13%
of assets during the period), for example, Fidelity National Financial (hurt by
rising mortgage rates) was a drag on our returns. So were companies like
American Homestar and Nobility Homes in the producer-durables sector, and
General Cable in the materials & processing sector. The lesson here is to be
more sensitive to selling when dealing with above-"trend line" earnings that
appear cheap.

STRATEGY AND OUTLOOK

We continue to see good earnings from most of our companies, though the growth
rate has moderated from about 20% in our last report to about 15% currently.
This pace still compares favorably with overall growth in corporate profits.
Many companies undoubtedly face a greater challenge in achieving revenue
growth, given tough pricing pressures. In addition, costs of readying computer
systems for Year 2000 are causing spending delays for some. Although the Y2K
effect is presumably temporary, its passing may not prompt companies to
automatically restore earlier spending patterns. Therefore, we look for
companies


                                       16
<PAGE>   19


that offer solutions for revenue enhancement to their customers, such as the
technology firms BroadVision, Acxiom, and Exchange Applications. Overall,
technology stocks now represent about 25% of the portfolio. Health-care stocks,
at 14% of assets, and consumer-discretionary holdings, at 25% of assets, are
other important commitments emphasizing companies with proprietary market
positions.

    Overall, stock valuations are high, although the average P/E
(price/earnings) ratio of 19.5 for our holdings pales in comparison with P/Es
of some larger companies. For example, the S&P 500 Index now has an average P/E
of 32. As noted, our companies are still showing relatively strong earnings
growth of about 15%, well above the trend for overall corporate profits. To be
sure, our P/E of 19.5, when compared with our 15% earnings growth rate,
represents a relatively high ratio by past standards. Our focus in adding new
names to the portfolio is on companies that are showing accelerating growth in
earnings.

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 up to $1 billion) 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 rose 16.7% over the six months ended March 31,
1999. Over the same period, the MSCI EAFE Index of developed international
stock markets gained 22.5% and the average international equity mutual fund
advanced 18.2%.

    Much has changed since my letter to you six months ago. Most important, the
developed world's central banks have dramatically relaxed monetary policy,
which unleashed the sharp rise in global stock markets that is reflected in the
performance of both the EAFE Index and, to a lesser extent, the portfolio. Your
portfolio was too defensively invested for this surge in stocks. Also, more
recently, cyclical stocks have been stronger than the growth stocks that your
portfolio emphasizes.

    In many stock markets, a significant easing of monetary policy usually
presages a pronounced period of rising share prices. However, in Europe as
opposed to Asia, this rise has already occurred, although to a lesser extent in
the United Kingdom than in the rest of Europe. In Asia, the Japanese economy
remains mired in recession after five consecutive quarters of falling economic
output. The issue to be resolved in Japan is whether sufficient action will be
taken by companies to improve profit margins, at a time of falling sales, to
support rising share prices. In my opinion, the outlook for the rest of Asia is
tied to the outlook for Japan, the world's second-largest economy (after the
United States).

    Against this background, I have added significantly to the portfolio's
exposure to United Kingdom stocks, which now account for 19% of our assets. The
U.K. economy is very sensitive to movements in interest rates, and the
cumulative reduction of 2.25 percentage points in short-term rates over the
past six months has boosted by 7% a typical household's disposable income after
housing finance costs. Accordingly, we have bought into companies that will
benefit from the likely pickup in consumer spending.

    The portfolio's largest exposure remains in continental Europe, where 58%
of assets are invested. The launch of a single currency, the euro, for most of
Europe has created more competitive business conditions, adding urgency to the
restructuring of companies and to the ongoing wave of mergers and acquisitions.
In this respect, the environment in continental Europe resembles that of the
United States in the early 1980s; our optimism is based on expectations of
strong corporate profit growth for several years.

    The portfolio's 13% commitment to Japanese stocks reflects a cautious view
of that market. We have selected 15 companies, of which the 3 largest holdings
represent more than half of our exposure. In addition to taking this highly
selective stance, we have hedged much of the related currency exposure back to
U.S. dollars to protect against anticipated weakness in the yen.

Richard Foulkes

April 15, 1999

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. U.S. Treasury securities
are considered to have the highest credit quality.

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 instruments. This
figure does not include cash invested in futures contracts to simulate stock or
bond investment.

                                       25
<PAGE>   28
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 equity assets represented by
stocks or American Depositary 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 (Treasury/agency, investment-grade
corporate, or below investment-grade).

MEDIAN MARKET CAP. An indicator of the size of companies in which a portfolio
invests; the midpoint of market capitalization (market price x shares
outstanding) of a portfolio's stocks, weighted by the proportion of the
portfolio's assets invested in each stock. Stocks representing half of the
portfolio's assets have market capitalizations above the median, and the rest
are below it.

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 period. 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.

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 detailed in the Statement of Operations. Because the Money Market,
Short-Term Corporate, 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.

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, Short-Term Corporate, High-Grade Bond, High Yield Bond, Balanced, Equity
Income, Diversified Value, Equity Index, Mid-Cap Index, Growth, Small Company
Growth, International, and REIT Index Portfolios. Each portfolio's shares are
only available for purchase by separate accounts of insurance companies as
investments for variable annuity plans or variable life insurance contracts.

      Certain investments of the Money Market, Short-Term Corporate, 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:
Equity securities 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. Prices are taken from the
primary market in which each security trades. 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. Securities for which market
quotations are not readily available are valued by methods deemed by the Board
of Trustees to represent fair value.

      2. FOREIGN CURRENCY: Securities and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars at the
exchange rates on the valuation date as employed by Morgan Stanley Capital
International in the calculation of its indexes.

      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 Short-Term Corporate Portfolio may use Municipal Bond Index, U.S.
Treasury Bond, and U.S. Treasury Note futures contracts, with the objectives of
enhancing returns, managing interest-rate risk, maintaining liquidity,
diversifying credit risk, and minimizing transaction costs. The portfolio may
purchase or sell futures contracts instead of bonds to take advantage of pricing
differentials between the futures contracts and the underlying bonds. The
portfolio may also seek to take advantage of price differences among bond market
sectors by simultaneously buying futures



                                       59

NOTES TO FINANCIAL STATEMENTS (continued)

(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 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.

      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. 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.

      6. DISTRIBUTIONS: Distributions of net investment income to shareholders
of the Money Market, Short-Term Corporate, 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 Income, Diversified Value, Equity Index, Mid-Cap Index,
Growth, Small Company Growth, International, and REIT Index Portfolios are
recorded on the ex-dividend date. Annual distributions from realized capital
gains, if any, are recorded on the ex-dividend date.

      7. OTHER: Dividend income is recorded on the ex-dividend date. The REIT
Index Portfolio's dividend income includes some payments that represent a return
of capital from its REIT investments. The amount of such return of capital is
only determined by each REIT after its fiscal year ends. No estimate of return
of capital distributions has been recorded in the financial statements. 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, Short-Term Corporate, High-Grade Bond, Equity Index, Mid-Cap Index, and
REIT Index Portfolios on an at-cost basis.

      Wellington Management Company, LLP; Newell Associates; Barrow, Hanley,
Mewhinney & Strauss, Inc.; and Lincoln Capital Management Company provide
investment advisory services to the High Yield Bond, Equity Income, Diversified
Value, and Growth Portfolios, respectively. For the period ended March 31, 1999,
the investment advisory fees of the High Yield Bond, Equity Income, Diversified
Value, and Growth Portfolios represented effective annual rates of 0.06%, 0.10%,
0.125%, 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

the six months ended March 31, 1999, the investment advisory fee represented an
effective annual basic rate of 0.09% of the portfolio's average net assets
before a decrease of $44,000 (0.01%) 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. The basic fee is subject to quarterly
adjustments based on performance relative to the Russell 2000 Index and,
beginning January 1, 1998, an index of the stocks held by the largest small
capitalization stock mutual funds. For the six months ended March 31, 1999, the
investment advisory fee represented an effective annual basic rate of 0.15% of
the portfolio's average net assets before an increase of $9,000 (0.01%) 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 for the preceding three years
relative to the Morgan Stanley Capital International Europe, Australasia, Far
East Index. For the six months ended March 31, 1999, the investment advisory fee
represented an effective annual basic rate of 0.13% of the portfolio's average
net assets before an increase of $26,000 (0.02%) 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 each portfolio under methods approved by the Board of Trustees. Each
portfolio has committed to provide up to 0.40% of its net assets in capital
contributions to Vanguard. At March 31, 1999, the portfolios had contributed
capital to Vanguard (included in Other Assets) of:

                             named for HMS Vanguard,
                        Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                          John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                 description, it was absolutely irresistible."

                        The Vanguard Group's oldest fund,
                         was incorporated by Mr. Morgan

VANGUARD VARIABLE INSURANCE FUND

FINANCIAL STATEMENTS
MARCH 31, 1999 (UNAUDITED)

The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appear in 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 that distribute
net income to shareholders as a dividend each day usually have no Undistributed
Net Investment 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.
