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. 

This year, 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, 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.

- - The 70th anniversary, on December 28, 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.

Financial markets were far from placid during the twelve months ended January
31, 1999, the fiscal year for the Vanguard Specialized Funds, and the funds'
performance fully reflected the markets' volatility.

      While large-capitalization stocks in the United States and Europe had a
banner year, the stocks of oil, gold, and real estate companies fell in response
to slumping commodity prices and concerns about overcapacity. Each of the five
Vanguard Specialized Funds earned a return reflecting the fate of its sector of
the market: strong gains for the health-care and utility sectors, declines for
energy, precious metals, and real estate investment trusts. The table at right
presents the total return (capital change plus reinvested dividends) for each
fund compared with those of its average peer and an unmanaged index benchmark.

      Detailed per-share figures, including net asset values at the beginning
and end of the year, income dividends, and any capital gains distributions, are
presented in the table that follows this letter.

FINANCIAL MARKETS IN REVIEW

The U.S. economy advanced powerfully during the twelve months ended January 31.
U.S. consumers provided the economic fuel with their free spending, encouraged
by a strong labor market (unemployment was just 4.3% at fiscal year-end) and
rising wages (up about 4%). Economic woes continued to beset Asia, where Japan,
the world's second-largest economy, remained mired in recession, and stagnation
afflicted several smaller economies. Latin America caught the "Asian contagion,"
and Brazil, the world's eighth-largest economy, was forced to devalue its
currency late in the fiscal year. Yet for American consumers, troubles abroad
translated into low prices at home. Consumer prices rose just +1.7%, restrained
by sharply lower energy prices, which were depressed in part by weak demand from
sluggish foreign economies.

      The optimism reflected in consumer spending was evident in U.S. financial
markets, too. True, there was a steep midsummer slump that saw stock prices
decline by -20% or more from mid-July through August. However, the market
bounced back strongly, aided by lower interest rates and a lack of evidence that
the weakness overseas would pull the U.S. economy into recession. By fiscal
year-end, the Standard & Poor's 500 Composite Stock Price Index had not only
recovered its midyear losses but had climbed to an all-

                                       1
<PAGE>   4
time high, achieving a remarkable +32.5% return for the twelve months ended
January 31. Within the S&P 500, there was a huge gap between returns of growth
stocks (+45.9%) and value stocks (+18.5%). The total U.S. stock market, as
measured by the Wilshire 5000 Equity Index, gained +27.4%. However, small-cap
stocks, as measured by the Russell 2000 Index, earned a scant +0.3% return.

      Interest rates declined on balance during the fiscal year, reflecting the
subdued level of inflation. Rates fell furthest for U.S. Treasury securities,
which benefited from a midyear "flight to quality" by investors eager to escape
the global gyrations of equity and currency markets. The yield on the 30-year
U.S. Treasury bond fell by 71 basis points (0.71 percentage point), from 5.80%
when the fiscal year began to 5.09% as of January 31, 1999. Prices of existing
bonds--which move in the opposite direction from interest rates-- rose,
accounting for 1.5 percentage points of the +8.1% return of the Lehman Aggregate
Bond Index.

      Short-term interest rates also fell by about 70 basis points, with the
yield on 3-month Treasury bills ending the fiscal year at 4.45%. The "yield
curve" remained relatively flat throughout the year--the spread between yields
on 3-month T-bills and 30-year Treasury bonds was a narrow 0.64 percentage point
at fiscal year-end.

FISCAL 1999 PERFORMANCE OVERVIEW

Our funds turned in decidedly mixed results during the fiscal year. The Health
Care and Utilities Income Funds achieved large gains, while our Energy, Gold and
Precious Metals, and REIT Index Funds suffered sizable declines. When measured
against our competitors, however, our results were pretty consistently
favorable: Four of our five funds outperformed their average peers, and the lone
exception, the REIT Index Fund, trailed its average competitor by about 1
percentage point. A detailed look at each fund's performance during fiscal 1999
and over the longer term follows.

ENERGY FUND

The Energy Fund's -21.2% return in fiscal 1999 was disappointing. However, we
note that it was 3.4 percentage points better than the -24.6% decline for the
average natural resources fund, making fiscal 1999 the seventh consecutive year
in which we outperformed our average peer. What made the energy sector's decline
especially painful was that it occurred while the S&P 500 Index was gaining
+32.5%.

      Energy stocks suffered because their earnings fell along with prices for
oil, refined petroleum products, and natural gas, all of which plummeted for a
second consecutive year. Prices for crude oil and refined products such as
gasoline and heating oil fell by 30%-35% during the fiscal year, while natural
gas prices fell by more than 20%. These price declines forced energy companies
to slash spending on capital projects, thereby depressing the revenues and stock
prices of oil-services, exploration, and pipeline companies. Our fund
outperformed its average peer largely because several stocks chosen by our
adviser, Wellington Management Company, benefited from takeover activity.

      As always, we also benefited from our low operating costs. Our expenses
amounted to 0.41%, or $4.10 per $1,000 in assets, which was less than
one-quarter the 1.68% ($16.80 per $1,000) expense ratio of the average natural
resources fund. This advantage of nearly 1.3 percentage points accounts for
about one-third of our fund's average margin of 4.5 percentage points per year
over peers during the past decade.

      The table at the top of page 3 presents the average annual return for the
decade ended January 31, 1999, for our fund, the average natural resources fund,
and the S&P 500 Index. It also shows the final value of hypothetical $10,000
investments made in 

                                       2
<PAGE>   5
each ten years ago, assuming that dividends and capital gains distributions had
been reinvested. The energy sector trailed far behind the overall stock market.
However, it is some consolation that a $10,000 investment in our fund would have
grown to $24,804, $8,482 more than the $16,322 ending value of a $10,000
investment in our average peer. Our margin is equal to nearly 85% of the initial
capital invested.

</TABLE>

      We caution against viewing the past decade's results as an indicator of
the next decade's. The past ten years were an unusually favorable period for the
S&P 500 Index, and a so- so period for energy stocks. As demonstrated by events
during fiscal 1999--and, indeed, during the past decade--prices of energy
products and energy stocks do not necessarily move in sync with overall stock
market prices. Indeed, it is precisely because the fortunes of energy companies
aren't in lockstep with those of other firms that some investors choose to
diversify by holding energy stocks.

GOLD AND PRECIOUS METALS FUND

The Gold and Precious Metals Fund declined -11.1% during fiscal 1999, a result
that was favorable only in comparison with our peers and our market sector, both
of which lagged far behind us: The average gold mutual fund fell -17.1% and the
Salomon Smith Barney Global Gold Equity Index fell -19.4%. The sector suffered
because gold and other precious metals became less precious. An ounce of gold
fetched about $290 as of January 31, down $14, or about 5%, from an
already-depressed price of $304 a year ago. Prices of silver and platinum fell
on balance by about 8% during the fiscal year. The prices of mining company
stocks tend to move even more--lower or higher--than the prices of the metals
the companies produce.

      Gold prices rallied early in the fiscal year, but headed lower for a
variety of reasons. Serious economic troubles dented the demand for gold in
Asia, a region where many individuals have traditionally held their personal
wealth in the form of jewelry and bullion. Inflation fears dissipated,
eliminating another traditional reason some investors own gold and gold-mining
stocks. Also, the possibility that central bankers around the world will
continue to liquidate their stockpiles of gold weighs on the market.

</TABLE>

      Over the decade ended January 31, 1999, gold and precious-metals stocks
have produced negative returns, reflecting the falling prices for metals. Our
fund's average annual return was -1.5%, which meant that a $10,000 investment in
the fund a decade ago would have shrunk, even with dividend and capital gains
distributions reinvested, to $8,592, a -14% decline in the initial capital
invested. As disappointing as it was, this result was considerably better than
that of the average gold fund, which produced an average annual decline of
- -4.0%. A $10,000 investment made ten years ago in our average peer would now be

                                       3
<PAGE>   6
worth $6,632, nearly $2,000 less than the ending value of the same investment in
our fund. Neither our fund nor the average gold fund kept pace with the index
benchmark, which declined an average of -0.4% annually during the decade.

      Our 2.5-percentage-point annual edge over our average peer was due both to
our wide cost advantage over the typical gold fund and to the solid job done by
our investment adviser, M&G Investment Management. Our fund's fiscal 1999
expense ratio of 0.77%, or $7.70 per $1,000 in assets, is more than 1 percentage
point below the 1.90% ($19 per $1,000) charged by the average gold fund. The
unmanaged index, which exists only on paper, has no operating or transaction
costs, accounting for virtually all of its margin of superiority over our fund's
return.

       With the benefit of hindsight, it is abundantly clear that gold and
precious metals were not the sector to be in during the past decade, and
especially during the past three fiscal years, when the index lost more than
half its value. Unfortunately, the past does not illuminate the future, and no
one knows what is in store for the prices of precious metals and stocks of
mining companies in coming years. However, we can say that our strategy of
providing exposure to this sector through broad diversification and at the
lowest reasonable cost will not change.

HEALTH CARE FUND

The Health Care Fund had another superb year during fiscal 1999, both in an
absolute sense (our +37.4% return was the second best in our history) and in
relation to comparative standards. We earned more than twice the return of the
average health-care fund and beat even the S&P 500 Index by nearly 5 percentage
points.

      Large growth stocks, including the pharmaceutical companies that make up a
sizable portion of our fund, were the stock market's strongest performers. This
fact worked in our favor in comparison with some health-care funds, since we
held more large-cap stocks than our average competitor. But even among smaller
stocks, the selections of our adviser, Wellington Management Company, generally
performed very well.

      The fund's long-term record is, in a word, excellent. As the table at left
shows, our average annual return of +23.6% during the past decade was more than
double the long-term average return of about 11% a year from common stocks. Such
remarkable gains were, in large part, the result of owning companies in a growth
sector where tremendous scientific and technological advances are occurring. Of
course, other health-care funds also have had this fair wind at their backs, yet
our return has exceeded that of our average peer by an average of 2.8 percentage
points a year. When compounded over a decade, this performance advantage looms
large: Identical $10,000 investments made a decade ago in our fund and its
average peer, with dividends and capital gain distributions reinvested, would
have grown to $83,135 and $66,148, respectively. The difference of $16,987 is
equivalent to an astounding 170% of the initial investment.

</TABLE>

       Our superiority stemmed from both the skilled investment management
provided by Wellington Management Company and our wide cost advantage. Our
operating costs in 

                                       4
<PAGE>   7
fiscal 1999 amounted to 0.36% of average net assets, or $3.60 per $1,000 of
assets, less than one-fourth the expense ratio of 1.67%, or $16.70 per $1,000,
charged by the average health-care fund. Costs clearly matter: Our cost
advantage of 1.3 percentage points accounted for nearly half our margin over
peers during the past decade.

      We expect to maintain a large cost advantage over our peers. But we do not
expect either health-care stocks or our fund to indefinitely earn more than 20%
a year. The past decade was an extraordinary period for the health-care sector
and stocks in general. But there surely will be disappointing periods from time
to time, so we urge investors to maintain a long-term outlook and to avoid the
temptation to concentrate too much in any one sector, even one where past
returns have been so generous.

UTILITIES INCOME FUND

Utility stocks--especially those of telecommunications companies--performed well
during fiscal 1999, boosting the Utilities Income Fund to a +19.9% return. Our
return outpaced that of the average utility fund by 1.2 percentage points, but
neither our fund nor our average peer matched the +23.8% gain for our composite
index. The index is weighted to reflect our traditional allocation of 80% to
utility stocks (half in the S&P Utilities Index and half in the S&P Telephone
Index) and 20% to utility bonds.

      Our shortfall versus the composite index was primarily due to our
underweighting in telecommunications stocks, which earned far more than other
utility stocks during the period. The composite index has a 40% weighting in
this sector, while we held about 25% to 30% of assets in telecom stocks. Some of
the biggest gainers among telecommunications companies during fiscal 1999 paid
too little in dividends to fit within our mandate to provide a good income
stream.

      The fund outperformed its average peer, despite our policy of holding at
least 10% of our assets in long-term utility bonds, roughly three times the bond
allocation of the average utility fund. Although bonds performed well in fiscal
1999--the Lehman Utility Bond Index earned +9.2%--they lagged far behind stocks.

       In nearly seven years of operation, our Utilities Income Fund has
achieved comfortably higher returns than the average utility fund, even though
our higher bond allocation has been a modest hindrance during a bullish period
for stocks. A $10,000 investment in the fund at its inception on May 15, 1992,
would have grown to $24,960 as of January 31, more than $2,000 higher than the
$22,885 that would have resulted from an identical investment in our average
competitor. Neither we nor our peers matched the composite index, though
outperforming the index remains our goal.

       Our shortfall versus the index is partly due to the fact that the index
exists only on paper and has none of the operating or transaction costs that any
real-world fund incurs. However, we work hard to minimize the bite that
operating costs take from the returns our shareholders receive. Our operating
expenses in fiscal 1999 equaled a slender 0.38% of average net assets, more than
1 percentage point below the 1.50% expense ratio charged by the 


                                       5
<PAGE>   8
average utility fund. Lower costs, then, explain about two-thirds of the margin
we have achieved over our average peer. Costs matter, especially over the long
term.

      The past returns of our fund are no indication of future returns, which
could be lower or higher than those earned by the fund in its relatively short
lifetime.

REIT INDEX FUND

Share prices of real estate investment trusts (REITs) fell sharply during the
twelve months ended January 31, reversing gains achieved during the previous
year. Our REIT Index Fund declined -17.3%, a far cry from the returns of +30.3%
and +17.1% it earned in its first two fiscal years of operation. Our result was
slightly better than the -17.6% decline for our unmanaged benchmark, the Morgan
Stanley REIT Index, but slightly behind the -16.2% decline for the average real
estate fund.

      Analysts cited a number of reasons for the sector's disappointing
performance, including investor worries that too many new properties were being
developed, that some property prices had become inflated, and that some
individual REITs may have borrowed too much. In its role as banking regulator,
the Federal Reserve Board in June told bankers that rapid increases in loans to
REITs could indicate that lending standards had become too lax. Also, the stock
market had to absorb an increase in the supply of REIT shares, as some trusts
issued additional shares and others made their first public offerings of shares.
On the other hand, the U.S. economy kept expanding and millions of new jobs were
created, boosting the demand for office space and other real estate.

      Our fund has not yet reached its third birthday, so it's far too early to
judge its success or failure. However, we are encouraged that the fund's
lifetime return--an annualized average of +8.9%--is slightly ahead of the +8.7%
average earned by both the average real estate fund and our benchmark index.

      We noted one year ago that our fund's performance to that point-- an
annualized return of +27.9%--was "far higher than should be expected over the
long run from any investment; future returns will surely be lower." Of course,
we had no idea that our statement would be proven correct so quickly. The point
we sought to make then--and want to reiterate now after a period that brought
very different results--is that investors should have both realistic
expectations for returns and a long-term investment horizon. Just as we
cautioned against euphoria after a period of abnormally high returns, we suggest
today that investors avoid overreaction to a single year's downturn. We believe
that exposure to commercial real estate can add diversification to a
well-balanced portfolio and that an indexed approach to REITs is sound because
it entails broad diversification and low cost.

      Our fund's 0.26% expense ratio during fiscal 1999 was less than one-fifth
the 1.51% expense ratio charged by the average real estate fund. While cost is
only one factor in mutual fund returns, we believe it is an important element in
long-term results.

IN SUMMARY

We have consistently reminded our shareholders that wide fluctuations in returns
are an unavoidable risk of investing in narrow sectors of the stock market.
Events during fiscal 


                                       6

1999 demonstrated this fact once again, as returns of our five funds ranged from
very rewarding to very disappointing.

      For investors focused on the long term and willing to endure these
fluctuations, investing in discrete market segments can be a sensible way to add
diversification to a broadly balanced investment program based on a core of
mainstream stock funds, bond funds, and money market funds. Once an investor
adopts such a plan, suited to individual objectives, time horizon, and tolerance
for risk, we believe in "staying the course" toward long-term financial goals.

NOTE: You'll observe that we have made a minor change in the name of each of the
Vanguard Specialized Funds. We replaced "portfolio" with "fund" as part of a
broader effort to clarify the names in our fund lineup.


VANGUARD HEALTH CARE FUND'S NEW REDEMPTION FEE POLICY

The Board of Trustees of Vanguard Health Care Fund has decided to implement a
new redemption fee policy that takes effect for shares purchased after Friday,
April 16, 1999: We will extend from one to five years the period during which
shareholders will be assessed the 1% redemption fee, which aims to discourage
short-term trading and is paid directly to the fund to compensate long-term
shareholders for trading costs.

       Your Trustees took this step to better protect the fund's long-term
shareholders from the potentially negative effects of speculative investing in
the fund. The fund's remarkable performance in recent years generated a dramatic
increase in new investments. We were concerned that some of this cash flow was
from investors who were chasing "hot" performance and who intended to redeem
their shares quickly when the fund's performance cools, as it no doubt will at
some point.

       Your Trustees also decided to temporarily close the fund to new
shareholder accounts as Vanguard implements the new policy. The closure began at
the close of business on February 25, 1999, and is expected to last between six
months and one year. During this period, existing Health Care Fund shareholders
will be allowed to invest up to $25,000 in the fund and to maintain periodic
contributions to the fund through automatic investment or retirement plans.

       The current redemption fee policy, which continues for all shares
purchased on or before April 16, 1999 (no matter when redeemed), applies the 1%
fee to shares held less than one year, and no fee thereafter.

THE MARKETS IN PERSPECTIVE
YEAR ENDED JANUARY 31, 1999

[PHOTO]

The twelve months ended January 31, 1999, were a volatile yet generally
rewarding period for financial markets. Despite a sharp midsummer slump, the
U.S. stock market closed the year with large gains: The overall market, as
measured by the Wilshire 5000 Equity Index, was up 27.4%. Stocks got a boost
from low inflation and generally declining interest rates, which also buoyed the
bond market. Overseas, gains were concentrated in Europe's developed markets,
while stocks fell in Asia and in most emerging markets.

U.S. STOCK MARKETS

The equity rise was concentrated to an unusual degree in large-capitalization
growth stocks. Large-cap stocks, as measured by the S&P 500 Index, gained
+32.5%, while the small-cap Russell 2000 Index eked out only a 0.3% return.
Growth stocks far outpaced value stocks within both large- and small-cap
indexes. The S&P 500's growth stocks earned +45.9%, versus 18.5% for the value
stocks in the index, while the growth component of the Russell 2000 earned 7.2%,
versus -6.9% for the value-stock component.

       In part, this growth-stock bias reflected the market's infatuation with
technology stocks. The technology sector led others by a wide margin, with tech
stocks in the S&P 500 gaining an extraordinary 97%. The sector benefited both
from its rapid growth and from investors' belief that consumers and businesses
will keep spending freely on computer hardware, software, and services. There
was more than a hint of speculation in the air, too, as stocks related to the
burgeoning activity on the Internet skyrocketed.

</TABLE>

       Other strong sectors included utilities (+49%), particularly
telecommunications stocks, which are seen as big beneficiaries of the Internet
boom and of rising demand for such services as wireless communications. The
strength of consumer spending--Americans spent nearly every dollar of after-tax
income they earned--boosted the stocks of retailers and other companies in the
consumer-discretionary sector (+37%). Good earnings growth and higher product
prices led to gains for pharmaceutical companies and others in the health-care
sector (+35%).

       The worst-performing sectors were those directly affected by falling
commodity prices: the "other energy" category (-33%) and materials & processing
firms (-2%), such 



                                       9
<PAGE>   12

as paper, steel, and chemical makers. Integrated oil companies gained 7% as a
group, largely because merger activity boosted share prices.

       The midyear slide in stocks seemed to be part of a global reevaluation of
risk that affected fixed-income securities as well. Investors grew wary about
the impact of Asia's lingering economic troubles, which slowed activity for U.S.
and European manufacturers and dried up capital flows to emerging markets not
only in Asia but in Latin America.

       The S&P 500 Index fell by nearly 20% over six weeks in July and August
before making its impressive comeback. Small-cap stocks fell by nearly 40%
before they began to recover. Curiously, the rebound occurred even though the
international economic troubles did not disappear and U.S. corporate earnings
were essentially flat. The rise in stock prices, combined with a lack of
earnings growth, pushed up the price/earnings ratio for the S&P 500 to about 32
by fiscal year-end, a level roughly twice its long-term average.

U.S. BOND MARKETS

Interest rates for most fixed-income securities declined on balance during the
fiscal year, falling most steeply for U.S. Treasury securities. Bond prices move
in the opposite direction from interest rates, so Treasuries enjoyed the biggest
price increases. Bonds gener-ally were helped by low inflation--consumer prices
rose by 1.7% from January 1998 to January 1999.

       Treasury securities in particular benefited from the summertime shakeup
in global markets because they are regarded as safe from defaults. Treasury
prices also got a boost from a slight shrinkage in supply due to the federal
government's growing budget surplus. Yields on Treasury securities fell on
balance by approximately 70 to 80 basis points (0.7 to 0.8 percentage point). At
fiscal year-end, Treasury yields ranged from 5.09% for the benchmark 30-year
bond to 4.45% for 3-month T-bills.

       Yields did not fall as far for high-quality corporate and municipal
bonds. Yields for lower-quality bonds increased and their prices declined,
reflecting investors' increased aversion to risk. Mortgage-backed bonds
generally did not benefit from falling rates because investors feared that this
would lead to rapid prepayments by homeowners refinancing their home loans.

INTERNATIONAL STOCK MARKETS

European stocks as a group gained 22.8% in U.S.-dollar terms, with about 5.5
percentage points of the gain due to a fall in the dollar's value versus
European currencies during the fiscal year. However, pickings were slim
elsewhere for U.S. investors venturing abroad. Pacific-region stocks, which are
dominated by recession-wracked Japan, fell by more than 7% in local currencies.
This decline was cushioned by the effect of a weaker dollar, so that for U.S.
investors the decline in Pacific-region stocks amounted to 2.1% for the fiscal
year. Overall, the Morgan Stanley Capital International Europe, Australasia, Far
East (EAFE) Index, a gauge of developed international markets, rose 14.7%.

       Investors in emerging markets were hit by a double whammy: lower stock
prices and a decline in the value of local currencies in relation to the U.S.
dollar. The result was an average decline of 14.2% for emerging markets, even
though several Asian markets (the Philippines, Indonesia, and Hong Kong) began
to rebound from sharp losses that occurred during 1997 and 1998. Latin American
stocks were the big losers, with declines of 53% for Brazil and 24% for Mexico.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP

ENERGY FUND

[PHOTO]

Returns in the energy sector again fell well short of the overall stock market's
gains during the fiscal year ended January 31, 1999. Vanguard Energy Fund
declined 21.2% during the period, compared with the 32.5% gain of the S&P 500
Index.

       The energy market has been severely depressed by four events: first, the
decision late in 1997 by the Organization of Petroleum Exporting Countries
(OPEC) to increase its members' production quotas; second, the sharp decline in
economic activity in Asia; third, unusually mild winter weather; and finally,
the rapid return of Iraqi oil to the world market. The OPEC cartel, with the
help of some other producers, tried to stabilize the market in 1998, but the
production cuts agreed upon were not large enough to absorb the excess
inventories created in 1997 and early 1998.

       Large, integrated companies such as Amoco, which merged with British
Petroleum, and Exxon provided positive returns during our fiscal year, but there
were declines in all other sectors, including refining, production, and oil
services. The price of oil, currently around $12 per barrel, is too low to
provide acceptable returns, and toward the end of 1998, production outside of
OPEC began to decline. Growth in petroleum demand has been lackluster because of
Asia's economic slump and the mild winters, and we expect oil production outside
of OPEC to continue declining during 1999 and 2000. Falling output ultimately
should stabilize the market if the cartel does nothing to reduce the inventory
overhang.

       Natural-gas markets in North America have also been unusually weak, but
should recover as well, given the short reserve life of most fields and sharp
reductions in drilling for new supplies.

       The decline in oil prices has been more severe and longer-lasting than we
expected, but we are encouraged by recent projections from the International
Energy Agency (IEA). The agency said that, with oil demand growing at about 2%
annually, massive investments will have to be made in the near future to provide
enough supplies. A 2% growth rate in demand would require 2 million barrels per
day of new capacity in the Middle East every year for the foreseeable future.
The IEA estimates that, even if oil prices were to rise 50% from current levels,
oil production outside of OPEC will decline by about 1% per year over the next
two decades.

       Our conclusion is that the current low prices of oil and gas and the
sharply reduced level of oil-field activity are caused by an unusual set of
circumstances. Low prices and cutbacks in production capacity are incompatible
with the increased volumes of oil and gas that will be needed in the future. We
are confident that, as in the past, booms and busts will alternate in this
industry, and we are being set up for a strong recovery in the not-too-distant
future.

REPORT FROM M&G INVESTMENT
MANAGEMENT LTD.

GOLD AND PRECIOUS METALS FUND

The fiscal year ended January 31 was an unrewarding period for gold investing.
Although the Gold and Precious Metals Fund declined by 11.1%, we are pleased
that the fund once again did much better than its comparative benchmarks: the
Salomon Smith Barney Global Gold Equity Index and the average gold mutual fund,
which declined by 19.4% and 17.1%, respectively.

       While the drop in the price of gold bullion reflected a lack of investor
interest in gold during the past year, gold shares were extremely volatile
nonetheless. The year's low point for gold stocks came at the end of August, but
it was followed by a strong rally over the next six weeks, as many of the
world's equity markets suffered from concern about hedge-fund collapses and
problems in Brazil and Russia. However, once the equity markets resumed their
march toward all-time highs, gold equities began to retreat, and the flat price
of bullion provided little support. By the end of our fiscal year, the gold
sector was once again subdued.

       The fund's strong performance in comparison with its peers and the index
was due to three factors. First, we largely avoided the speculative end of the
market, which continued to drop steeply. The few speculative stocks that we held
illustrated the point; for example, Princess Resources fell by 86% and
Greenstone Resources slid 91%. Second, we maintained the fund's significant
exposure to companies that produce platinum and paladium or diversified metals.
Such stocks included Stillwater Mining and Impala Platinum ADR, which rose by
100% and 64%, respectively. Rio Tinto and Anglo American Platinum ADR also
recorded strong gains. Third, a corporate turnaround instigated by new
management in Newcrest Mining, a major holding of ours, and a bid for our
holding in Getchell Gold led to impressive rises in both stocks.

       These positive factors were partly offset by the fund's comparatively low
exposure to Barrick Gold Corp., which continued to outperform the overall
precious-metals market, and by the weakness of the Australian dollar, which
diminished the value of our Australian holdings. Our stakes in Australian
diamond producer Ashton Mining and in Freeport-McMoRan Copper & Gold also hurt
our relative performance.

       We continued to raise the fund's exposure to blue chip companies during
the period by initiating holdings in two major Australasian producers, Lihir
Gold and Delta Gold. We liquidated shares of Philippine Gold, Ashanti
Goldfields, IAMGOLD, and TVX Gold. A number of our South African holdings have
consolidated into Anglogold ADR or Gold Fields ADR.

       The volatility of international stock markets during the past year
demonstrated that gold still can play a role as a hedge against slumping prices
for equities and bonds. Although the rally experienced by gold shares lasted
just six weeks, it showed that some investors still view gold as a safe haven in
times of extreme turbulence and that it has a role in a well-diversified
portfolio.

INVESTMENT PHILOSOPHY

Each fund reflects a belief that investors who seek to emphasize a given
economic sector as part of a long-term, balanced investment program are best
served by holding a portfolio of securities well-diversified across that sector.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP

HEALTH CARE FUND

Vanguard Health Care Fund had very positive results--a total return of 37.4%--in
the fiscal year ended January 31, 1999. This gain exceeded the returns of both
the S&P 500 Index (32.5%) and the S&P Health Sector Index (35.5%). It also
dramatically outpaced the 17.9% return of the average health-care mutual fund.

       This was the third year in a row that large-capitalization companies
dominated investment returns. The Health Care Fund benefited generally from this
trend, and particularly from standout performances from Warner-Lambert,
Pharmacia & Upjohn, and Pfizer.

       Surprisingly, however, the three largest contributors to the fund's
return during the fiscal year were smaller companies. DEKALB Genetics, acquired
at a significant premium by Monsanto, was our best-performing stock. Immunex,
now launching a breakthrough drug for rheumatoid arthritis, was our next-best
holding. Rejuvenated ophthalmic specialist Allergan was the third-largest
contributor to our return.

       Stock price appreciation and significant cash flow from new investors
have combined to more than double the size of the fund over the past year. It
reached $9.9 billion in assets as of January 31.

       We hope our new investors are not chasing after the fund's recent strong
performance, but rather are committed to participation in the long-term growth
of the health-care industry. Current stock valuations are much higher than
historical averages, so we may now face a more difficult period that will try
the patience of investors who are not focused on the long term.

       Our management style has not changed over the years. We take a relatively
conservative approach to portfolio management by maintaining broad
diversification across all areas of health care; paying close attention to
"value"--that is, the prices of stocks, not merely the current growth rate of
earnings; and taking a long-term view, as reflected in our low turnover. We
believe this approach will result in good returns relative to the health-care
market during periods of weakness, while providing full participation in the
growth of the sector over the long term.

       We remain confident that the health-care industry is one of the
best-positioned sectors in the economy for the long-term investor.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP

UTILITIES INCOME FUND

Vanguard Utilities Income Fund earned 19.9% for the fiscal year ended January
31, 1999. The fund's return was modestly higher than the 18.7% return for the
average utility fund, but fell behind the 23.8% return of the fund's unmanaged
benchmark, a composite weighted 40% in the S&P Utilities Index, 40% in the S&P
Telephone Index, and 20% in the Lehman Utility Bond Index.

       Once again, the telecommunications sector was the star performer among
utility stocks, as the group benefited from booming growth in Internet, data,
and wireless communications. Productivity gains and merger-and-acquisition
activity also had a hand in the 41.2% gain in the S&P Telephone Index for the
fiscal year.

       During the past 12 months, we saw WorldCom complete its merger with MCI
Communications; AT&T announce a landmark transaction with Tele-Communications
Inc. (TCI), one of the nation's largest cable companies; and the merger of
AirTouch Communications and Vodafone to form by far the world's largest wireless
telecommunications company. As can be expected in a strong market focused on
technology, the slow-growth electric and natural-gas utilities were relatively
poor performers during the year.

       As noted in previous reports, we have gradually reduced the fund's
weighting in bonds, which declined over the past six months from 15% of assets
to 12%. Most of the proceeds of these sales were put into the telecommunications
sector. We initiated a large position in AT&T and added to existing holdings in
Sprint, BellSouth, and Ameritech. We believe that through its proposed merger
with TCI, AT&T has made a bold move to potentially bypass the local telephone
companies. AT&T's new management is clearly changing the way the company is
perceived by the marketplace. Execution will be the telling factor for AT&T over
the next two years as the company digests recent acquisitions and improves its
global position in data, Internet, cable, and voice telecommunications. We
anticipate more consolidation in this fast-changing telecom environment, since
we do not expect Ma Bell's competitors to stand still.

       Stocks of electric utilities have been plagued by a lack of technological
change and the slow pace of state-by-state industry restructuring. The electric
sector has not had a significant technological development in decades--unlike
the telecom sector, where technology has raised productivity and demand. In the
natural-gas sector, disappointing exploration and production results, excess gas
storage, and another mild winter have depressed the near-term outlook. Both the
electric and gas industries look historically cheap versus the market and the
telephone utilities, but it is tough to see a catalyst that would spark investor
interest and an expansion in price/earnings multiples.

       Despite the bias toward growth in today's market--a tilt that favors the
telecom sector--the electric and gas companies provide a great number of
investment opportunities, and we will continue to take advantage of them,
particularly to meet our income goal. On a measured basis, we are also taking
advantage of foreign stock ideas that fit the fund's investment criteria:
quality and reasonable dividend income. Our exposure to non-U.S. names is
currently 10% of assets.

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

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

AVERAGE MATURITY. The average length of time until bonds held by a fund reach
maturity (or are called) and are repaid. In general, the longer the average
maturity, the more a fund'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 fund'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 fund'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 fund 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 fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate stock and
bond investment.

COUNTRY DIVERSIFICATION. The percentages of a fund's total net assets invested
in securities of various countries.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund'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 fund's holdings by type of issuer or
type of instrument.

DIVIDEND YIELD. The current, annualized rate of dividends paid on a share of
stock, divided by its current share price. For a fund, the weighted average
yield for stocks it holds.

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

EQUITY INVESTMENT FOCUS. This grid indicates the focus of a fund's equity
holdings in terms of two attributes: market capitalization (large, medium, or
small) and relative valuation (growth, value, or a blend).

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

FIXED-INCOME INVESTMENT FOCUS. This grid indicates the focus of a fund's
fixed-income holdings in terms of two attributes: average maturity (short,
medium, or long) and average credit quality (Treasury/agency, investment-grade
corporate, or below investment-grade). FOREIGN HOLDINGS. The percentage of a
fund's equity assets represented by stocks or American Depositary Receipts of
companies based outside the United States.

FUND ALLOCATION BY REIT TYPE. An indicator of diversification, this table shows
the percentage of the fund's noncash holdings invested in various real estate
investment trusts, classified according to the types of property they emphasize.

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

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

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

NUMBER OF STOCKS. An indicator of diversification. The more stocks a fund holds,
the more diversified it is and the more likely to perform in line with the
overall stock market.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a fund, 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 fund, 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 fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund'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 fund, the weighted average return on
equity for the companies whose stocks it holds.

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

TEN LARGEST HOLDINGS/STOCKS. The percentage of equity assets or of total net
assets that a fund has invested in its ten largest stocks. As this percentage
rises, a fund's returns are likely to be more volatile because they are more
dependent on the fortunes of a few companies.

TURNOVER RATE. An indication of trading activity during the past year. Funds
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 fund's income from interest and dividends. The yield,
expressed as a percentage of the fund's net asset value, is based on income
earned over the past 30 days 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.

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

FINANCIAL STATEMENTS

JANUARY 31, 1999

[PHOTO]

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each fund'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, bonds, etc.) and by sector
within the fund's designated industry; international securities, if significant,
may be presented in a separate group. The REIT Index Fund lists its security
holdings alphabetically. Other assets are added to, and liabilities are
subtracted from, the value of Total Investments to calculate the fund's Net
Assets. Finally, Net Assets are divided by the outstanding shares of the fund to
arrive at its share price, or Net Asset Value (NAV) Per Share.

      At the end of the Statement of Net Assets, you will find a table
displaying the composition of the fund'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 fund had available to distribute to shareholders as income dividends or
capital gains as of the statement date, but may differ because certain
investments or transactions may be treated differently for financial statement
and tax purposes. Any Accumulated Net Realized Losses, and any cumulative excess
of distributions over net income or net realized gains, will appear as negative
balances. Unrealized Appreciation (Depreciation) is the difference between the
market value of the fund's investments and their cost, and reflects the gains
(losses) that would be realized if the fund were to sell all of its investments
at their statement-date values.

STATEMENT OF OPERATIONS

This Statement shows dividend and interest income earned by each fund during the
reporting period, and details the operating expenses charged to the fund. These
expenses directly reduce the amount of investment income available to pay to
shareholders as dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period--these
amounts include the effect of foreign currency movements on the value of a
fund's securities. Currency gains (losses) on the translation of other assets
and liabilities are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. The amounts shown as Distributions to
shareholders from the fund's net income and capital gains 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
fund, 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 fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund'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 fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the fund's total return; how much it costs to operate the
fund; and the extent to which the fund tends to distribute capital gains. The
table also shows the Portfolio Turnover Rate, a measure of trading activity. A
turnover rate of 100% means that the average security is held in the fund for
one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Specialized Funds comprise the Energy, Gold and Precious Metals, Health
Care, Utilities Income, and REIT Index Funds, each of which is registered under
the Investment Company Act of 1940 as a diversified open-end investment company,
or mutual fund. The Energy, Gold and Precious Metals, Health Care, and Utilities
Income Funds may invest in securities of foreign issuers, which may subject them
to investment risks not normally associated with investing in securities of
United States corporations. Certain investments of the Utilities Income Fund are
in debt instruments for which the issuers' abilities to meet their obligations
may be affected by economic developments in the utilities industry.

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

      1. SECURITY VALUATION: 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. Precious metals are valued at the mean of the latest quoted bid and
asked 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. 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. FORWARD CURRENCY CONTRACTS: The Health Care Fund enters into forward
currency contracts to protect the value of securities and related receivables
and payables against changes in future foreign exchange rates. The fund'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.

      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 forward currency contract gains
(losses).

      4. EQUALIZATION: Prior to February 1998, the Utilities Income Fund
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 February 1, 1998, the fund
has discontinued equalization accounting and has reclassified accumulated net
equalization credits of $5,366,000 from undistributed net investment income to
paid in capital. This reclassification has no effect on the fund's net assets,
results of operations, or net asset value per share.

                                       46

<PAGE>   49


      5. REPURCHASE AGREEMENTS: The funds, 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 to shareholders are recorded on the
ex-dividend date. Distributions are determined on a tax basis and may differ
from net investment income and realized capital gains for financial reporting
purposes.

      7. OTHER: Dividend income is recorded on the ex-dividend date. Security
transactions are accounted for on the date securities are bought or sold. Costs
used to determine realized gains (losses) on the sale of investment securities
are those of the specific securities sold. Premiums and discounts on debt
securities purchased are amortized and accreted, respectively, to interest
income over the lives of the respective securities. Fees assessed on
redemptions of capital shares are credited to paid in capital.

B.    Wellington Management Company, LLP, provides investment advisory services
to the Energy, Health Care, and Utilities Income Funds for fees calculated at
an annual percentage rate of average net assets. For the year ended January 31,
1999, the investment advisory fees of the Energy, Health Care, and Utilities
Income Funds represented an effective annual rate of 0.07% of each fund's
average net assets.

      M&G Investment Management Ltd. provides investment advisory services to
the Gold and Precious Metals Fund for a fee calculated at an annual percentage
rate of average net assets. For the year ended January 31, 1999, the investment
advisory fee represented an effective annual rate of 0.22% of the fund's
average net assets.

      The Vanguard Group furnishes investment advisory services to the REIT
Index Fund on an at-cost basis.

C.    The Vanguard Group furnishes at cost corporate management,
administrative, marketing, and distribution services. The costs of such
services are allocated to each fund under methods approved by the Board of
Trustees. Each fund has committed to provide up to 0.40% of its net assets in
capital contributions to Vanguard. At January 31, 1999, the funds had
contributed capital to Vanguard (included in Other Assets) of:

The funds' Trustees and officers are also Directors and officers of Vanguard.

D.    Vanguard has asked the funds' investment advisers to direct certain
portfolio trades, subject to obtaining the best price and execution, to brokers
who have agreed to rebate to the funds part of the commissions generated. Such
rebates are used solely to reduce the funds' administrative expenses. The
funds' custodian banks have also agreed to reduce their fees when the funds

Net unrealized appreciation on open futures contracts is required to be treated
as realized gain for tax purposes.

      At January 31, 1999, the Health Care Fund had net unrealized foreign
currency gains resulting from the translation of other assets and liabilities
of $29,000.

G.    Distributions are determined on a tax basis and may differ from net
investment income and realized capital gains for financial reporting purposes.

      During the year ended January 31, 1999, the funds realized net foreign
currency gains (losses) that increased (decreased) distributable net income for
tax purposes; accordingly such gains (losses) have been reclassified from
accumulated net realized gains (losses) to undistributed net investment income
as follows:

      For federal tax purposes, Energy Fund capital gains required to be
distributed in December 1998 included net gains realized through October 31,
1998. Subsequently, the fund realized capital losses of $15,102,000 which are
available to offset future net capital gains.

      At January 31, 1999, the Gold and Precious Metals Fund had available
realized losses of $90,606,000 to offset future net capital gains of $2,873,000
through January 31, 2005, $19,472,000 through January 31, 2006, $67,666,000
through January 31, 2007, and $595,000 through January 31, 2008. Certain of the
fund's investments are in securities considered to be "passive foreign
investment companies," for which any unrealized appreciation and/or realized
gains are required to be included in distributable net income for tax purposes.
During the year ended January 31, 1999, the Gold and Precious Metals Fund
realized gains on the sale of passive foreign investment companies of $965,000,
which were included in prior years' distributable net income for tax purposes;
accordingly, such gains have been reclassified from accumulated net realized
losses to undistributed net investment income. The cumulative total of
distributions related to passive foreign investment company holdings at January
31, 1999, was $3,220,000, and is reflected in the balance of overdistributed net
investment income.

      The Utilities Income Fund had gains of $1,050,000 on securities held for
less than one year which are treated as ordinary income for tax purposes and
have been included in income dividends to shareholders; accordingly, such gains
have been reclassified from accumulated net realized gains to undistributed net
investment income.

      At January 31, 1999, the REIT Index Fund had available realized losses of
$39,785,000 to offset future net capital gains of $7,983,000 through January 31,
2007, and $31,802,000 through January 31, 2008.

REPORT OF INDEPENDENT
ACCOUNTANTS

[PHOTO]

To the Shareholders and Trustees of
Vanguard Specialized Funds

In our opinion, the accompanying statements of net assets (and statements of
assets and liabilities for Vanguard Energy Fund) and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of Vanguard Energy
Fund, Vanguard Gold and Precious Metals Fund, Vanguard Health Care Fund,
Vanguard Utilities Income Fund and Vanguard REIT Index Fund (constituting
Vanguard Specialized Funds, hereafter referred to as the "Funds") at January
31, 1999, the results of each of their operations for the year then ended, the
changes in each of their net assets for each of the two years in the period
then ended and the financial highlights for each of the 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 Funds' 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 January 31, 1999 by correspondence with the custodians and
brokers, provide a reasonable basis for the opinion expressed above.

                             The Vanguard Group is
                            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."

                        celebrated his 100th birthday on
                           July 23, 1998. Mr. Morgan,

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

                          Battle of Waterloo in 1815.
