SUPPLEMENT DATED SEPTEMBER 1, 2000 TO THE CURRENT PROSPECTUS
OF
MFS(R)/SUN LIFE SERIES TRUST (THE "SERIES FUND")
THIS SUPPLEMENT DESCRIBES TWO NEW SERIES OF THE SERIES FUND -- THE GLOBAL
TELECOMMUNICATIONS SERIES AND THE MID CAP GROWTH SERIES -- AND SUPPLEMENTS
CERTAIN INFORMATION IN THE SERIES FUND'S PROSPECTUS DATED MAY 1, 2000. THE
CAPTION HEADINGS USED IN THIS SUPPLEMENT CORRESPOND WITH THE CAPTION HEADINGS
USED IN THE PROSPECTUS. INFORMATION WHICH IS NOT SUPPLEMENTED APPLIES EQUALLY TO
THE NEW SERIES.
I EXPENSE SUMMARY -- BEGINNING ON PAGE 1
o EXPENSE TABLE
This table describes the expenses that you may pay when you hold shares of
the series. These fees and expenses do not take into account the fees and
expenses imposed under the Variable Contracts through which an investment in
the series is made. The table is supplemented as follows:
ANNUAL OPERATING EXPENSES (expenses that are deducted from the series'
assets):
..........................................................................
GLOBAL MID CAP
TELECOMMUNICATIONS GROWTH
SERIES SERIES
-------- --------
Management Fee ................................ 1.00% 0.75%
Other Expenses(1) ............................. 0.76% 0.67%
------- -------
Total Annual Series Operating Expenses(1) ..... 1.76% 1.42%
Fee Waivers/Expense Reimbursement(2) ...... (0.51)% (0.42)%
------- -------
Net Expenses(1) ........................... 1.25% 1.00%
------
(1) The series has an expense offset arrangement which reduces its custodian
fee based upon the amount of cash maintained by the series with its
custodian and dividend disbursing agent. The series may enter into other
similar arrangements and directed brokerage arrangements, which would
also have the effect of reducing the series' expenses. The series'
expenses do not take into account these expense reductions, and
therefore do not represent the actual expenses of the series.
(2) MFS has contractually agreed to bear the series' expenses such that
"Other Expenses" do not exceed 0.25% annually. This contractual
arrangement will continue until at least May 1, 2001, unless modified
with the consent of the board of trustees, which oversees the series.
o EXAMPLE OF EXPENSES
The "Example of Expenses" table is intended to help you compare the cost of
investing in the series with the cost of investing in other mutual funds.
The example assumes that:
o You invest $10,000 in the series for the time periods indicated and you
redeem your shares at the end of the time periods;
o Your investment has a 5% return each year and dividends and other
distributions are reinvested; and
o The series' operating expenses remain the same, except that the series'
total operating expenses are assumed to be the series' "Net Expenses" for
the first year, and the series' "Total Annual Series Operating Expenses"
for subsequent years (see table above).
The table is supplemented as follows:
Although your actual costs may be higher or lower, under these assumptions
your costs would be:
YEAR 1 YEAR 3

Global Telecommunications $127 $504
Mid Cap Growth Series $102 $408
II RISK RETURN SUMMARY -- BEGINNING ON PAGE 4
THIS SECTION OF THE PROSPECTUS IS SUPPLEMENTED AS FOLLOWS:
29: GLOBAL TELECOMMUNICATIONS SERIES
...........................................................................
o INVESTMENT OBJECTIVE
The series' investment objective is to achieve long-term growth of capital.
The series' objective may be changed without shareholder approval.
o PRINCIPAL INVESTMENT POLICIES
The series invests, under normal market conditions, at least 65% of its
total assets in common stocks and related securities, such as preferred
stock, convertible securities and depositary receipts, of telecommunications
companies from at least three countries, including the U.S.
Telecommunications companies are broadly defined to include companies
involved in the development, manufacturing, sale or servicing of
telecommunications equipment or services. For example, telecommunications
companies may include:
o issuers in the telephone, wireless communications (including cellular
telephone, microwave and satellite communications, paging and other
emerging wireless technologies), broadcasting, cable, computer,
electronic components, and networking industries;
o issuers involved in the creation and distribution of content, including
media, entertainment, communications, software, publishing, information
systems and data generation companies; and
o issuers in other telecommunications related industries including
companies involved in the support and development of the
telecommunications infrastructure.
Consistent with its investment objective, the series may also invest in
debt securities, including lower rated securities (i.e. "junk bonds"), and
short-term debt securities of governments, supranational agencies and other
corporations. The series' investments are not subject to any geographical
limitation and may include securities of issuers in emerging market
countries. The series' securities may be traded in the over-the-counter
markets.
The series focuses on companies of any size that the series' investment
adviser, MFS, believes have above average long-term growth potential or are
undervalued in the market relative to their long term potential (securities
with low price-to-book, price-to-sales and/or price-to- earnings ratios).
MFS looks particularly for companies which demonstrate:
o above average earnings growth over a sustained period of time;
o a strong franchise, strong cash flows and a recurring revenue stream;
o a solid industry position, where there is:
> potential for high profit margins; and
> substantial barriers to new entry in the industry;
o a strong management team with a clearly defined strategy; and
o a catalyst that may accelerate growth.
MFS uses a bottom-up, as opposed to a top-down, investment style in
managing the equity-oriented funds (such as the series) it advises. This
means that securities are selected based upon fundamental analysis (such as
an analysis of earnings, cash-flows, competitive position and management's
abilities) performed by the series' portfolio manager and MFS' large group
of equity research analysts.
The series is a non-diversified mutual fund. This means that the series
may invest a relatively high percentage of its assets in a small number of
issuers. The series may also invest a substantial amount of its assets
(i.e., more than 25% of its assets) in issuers located in a single country
or a limited number of countries.
The series may engage in active and frequent trading to achieve its
principal investment strategies.
o PRINCIPAL RISKS
The principal risks of investing in the series and the circumstances
reasonably likely to cause the value of your investment in the series to
decline are described below. The share price of the series generally changes
daily based on market conditions and other factors. Please note that there
are many circumstances which could cause the value of your investment in the
series to decline, and which could prevent the series from achieving its
objective, that are not described here.
The principal risks of investing in the series are:
o Telecommunications Sector Risk: The value of securities of
telecommunications companies is particularly vulnerable to rapidly
changing technology, relatively high risks of obsolescence caused by
technological advances, and intense competition. For these and other
reasons, securities of telecommunications companies may be more volatile
than the overall market. The telecommunications sector is subject to
certain pro-competitive governmental policies and government regulation
of rates and services that may be offered, and changes in these
regulations may adversely affect the value of the telecommunications
company securities held by the series. In addition, because the series
will invest a substantial amount of its assets in the telecommunications
sector, it assumes the risk that financial, regulatory, business,
economic and political conditions affecting this sector will have a
significant impact on its investment performance. The series' investment
performance may also be more volatile because it concentrates its
investments in a single sector.
o Industry Concentration Risk: Because the series will invest a substantial
amount of its assets in issuers located in a group of related industries
(the telecommunications sector), it assumes the risk that financial,
regulatory, business, economic and political conditions affecting these
industries will have a significant impact on its investment performance.
The series' investment performance may also be more volatile because it
concentrates its investments in a single sector.
o Market Risk: This is the risk that the price of a security held by the
series will fall due to changing economic, political or market conditions
or disappointing earnings results.
o Company Risk: Prices of securities react to the economic condition of the
company that issued the security. The series' equity investments in an
issuer may rise and fall based on the issuer's actual and anticipated
earnings, changes in management and the potential for takeovers and
acquisitions.
o Non-Diversified Status Risk: Because the series may invest a higher
percentage of its assets in a small number of issuers, the series is more
susceptible to any single economic, political or regulatory event
affecting those issuers than is a diversified series.
o Foreign Markets Risk: Investing in foreign securities involves risks
relating to political, social and economic developments abroad, as well
as risks resulting from the differences between the regulations to which
U.S. and foreign issuers and markets are subject:
> These risks may include the seizure by the government of company
assets, excessive taxation, withholding taxes on dividends and
interest, limitations on the use or transfer of portfolio assets, and
political or social instability.
> Enforcing legal rights may be difficult, costly and slow in foreign
countries, and there may be special problems enforcing claims against
foreign governments.
> Foreign companies may not be subject to accounting standards or
governmental supervision comparable to U.S. companies, and there may
be less public information about their operations.
> Foreign markets may be less liquid and more volatile than U.S.
markets.
> Foreign securities often trade in currencies other than the U.S.
dollar, and the series may directly hold foreign currencies and
purchase and sell foreign currencies through forward exchange
contracts. Changes in currency exchange rates will affect the series'
net asset value, the value of dividends and interest earned, and gains
and losses realized on the sale of securities. An increase in the
strength of the U.S. dollar relative to these other currencies may
cause the value of the series to decline. Certain foreign currencies
may be particularly volatile, and foreign governments may intervene in
the currency markets, causing a decline in value or liquidity in the
series' foreign currency holdings. By entering into forward foreign
currency exchange contracts, the series may be required to forego the
benefits of advantageous changes in exchange rates and, in the case of
forward contracts entered into for the purpose of increasing return,
the series may sustain losses which will reduce its gross income.
Forward foreign currency exchange contracts involve the risk that the
party with which the series enters the contract may fail to perform
its obligations to the series.
o Emerging Markets Risk: Emerging markets are generally defined as
countries in the initial stages of their industrialization cycles with
low per capita income. Investments in emerging markets securities involve
all of the risks of investments in foreign securities, and also have
additional risks:
> All of the risks of investing in foreign securities are heightened by
investing in emerging markets countries.
> The markets of emerging markets countries have been more volatile than
the markets of developed countries with more mature economies. These
markets often have provided significantly higher or lower rates of
return than developed markets, and significantly greater risks, to
investors.
o Geographic Focus Risk: Because the series may invest a substantial amount
of its assets in issuers located in a single country or a limited number
of countries, economic, political and social conditions in these
countries will have a significant impact on its investment performance.
o Growth Companies Risk: Prices of growth company securities held by the
series may fall to a greater extent than the overall equity markets
(e.g., as represented by the Standard and Poor's Composite 500 Index) due
to changing economic, political or market conditions or disappointing
growth company earnings results.
o Undervalued Securities Risk: The series may invest in securities that are
undervalued based on its belief that the market value of these securities
will rise due to anticipated events and investor perceptions. If these
events do not occur or are delayed, or if investor perceptions about the
securities do not improve, the market price of these securities may not
rise as expected or may fall.
o Effect of IPOs: The series may participate in the initial public offering
("IPO") market, and a significant portion of the series' returns may be
attributable to its investment in IPO's which may have a magnified
investment performance impact during the periods when the series has a
small asset base. Like any past performance, there is no assurance that,
as the series' assets grow, it will continue to experience substantially
similar performance by investment in IPOs.
o Over-the-Counter Risk: Over-the-counter (OTC) transactions involve risks
in addition to those associated with transactions in securities traded on
exchanges. OTC-listed companies may have limited product lines, markets
or financial resources. Many OTC stocks and fixed income securities trade
less frequently and in smaller volume than exchange-listed securities.
The values of OTC stocks may be more volatile than exchange-listed
stocks, and the series may experience difficulty in purchasing or selling
these securities at a fair price. OTC fixed income securities are subject
to liquidity risk. This means that they may be harder to purchase or sell
at a fair price. The inability to purchase or sell these fixed income
securities at a fair price could have a negative impact on the series'
performance.
o Active or Frequent Trading Risk: The series may engage in active and
frequent trading to achieve its principal investment strategies. This may
result in the realization and distribution to shareholders of higher
capital gains as compared to a fund with less active trading policies,
which would increase your tax liability. Frequent trading also increases
transaction costs, which could detract from the series' performance.
o Fixed Income Securities Risk:
> Interest Rate Risk: When interest rates rise, the prices of fixed
income securities in the series' portfolio will generally fall.
Conversely, when interest rates fall, the prices of fixed income
securities in the series' portfolio will generally rise.
> Maturity Risk: Interest rate risk will generally affect the price of a
fixed income security more if the security has a longer maturity.
Fixed income securities with longer maturities will therefore be more
volatile than other fixed income securities with shorter maturities.
Conversely, fixed income securities with shorter maturities will be
less volatile but generally provide lower returns than fixed income
securities with longer maturities. The average maturity of the series'
fixed income investments will affect the volatility of the series'
share price.
> Credit Risk: Credit risk is the risk that the issuer of a fixed income
security will not be able to pay principal and interest when due.
Rating agencies assign credit ratings to certain fixed income
securities to indicate their credit risk. The price of a fixed income
security will generally fall if the issuer defaults on its obligation
to pay principal or interest, the rating agencies downgrade the
issuer's credit rating or other news affects the market's perception
of the issuer's credit risk.
> Liquidity Risk: The fixed income securities purchased by the series
may be traded in the over-the-counter market rather than on an
organized exchange and are subject to liquidity risk. This means that
they may be harder to purchase or sell at a fair price. The inability
to purchase or sell these fixed income securities at a fair price
could have a negative impact on the series' performance.
o Lower Rated Bonds Risk:
> Higher Credit Risk: Junk bonds are subject to a substantially higher
degree of credit risk than higher rated bonds. During recessions, a
high percentage of issuers of junk bonds may default on payments of
principal and interest. The price of a junk bond may therefore
fluctuate drastically due to bad news about the issuer or the economy
in general.
> Higher Liquidity Risk: During recessions and periods of broad market
declines, junk bonds could become less liquid, meaning that they will
be harder to value or sell at a fair price.
o As with any mutual fund, you could lose money on your investment in the
series.
An investment in the series is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.
o BAR CHART AND PERFORMANCE TABLE
The bar chart and performance table are not included because the series had
not commenced investment operations as of December 31, 1999.
30: MID CAP GROWTH SERIES
..........................................................................
o INVESTMENT OBJECTIVE
The series' investment objective is long-term growth of capital. The series'
objective may be changed without shareholder approval.
o PRINCIPAL INVESTMENT POLICIES
The series invests, under normal market conditions, at least 65% of its
total assets in common stocks and related securities, such as preferred
stocks, convertible securities and depositary receipts for those securities,
of companies with medium market capitalizations which the series' investment
adviser, MFS, believes have above-average growth potential.
Medium market capitalization companies are defined by the series as
companies with market capitalizations equaling or exceeding $250 million but
not exceeding the top of the Russell Midcap(TM) Growth Index range at the
time of the series' investment. This Index is a widely recognized, unmanaged
index of mid-cap common stock prices. Companies whose market capitalizations
fall below $250 million or exceed the top of the Russell Midcap(TM) Growth
Index range after purchase continue to be considered medium-capitalization
companies for purposes of the series' 65% investment policy. As of July 31,
2000, the top of the Russell Midcap(TM) Growth Index range was $ billion.
The series' investments may include securities listed on a securities
exchange or traded in the over-the-counter markets.
MFS uses a bottom-up, as opposed to a top-down, investment style in
managing the equity-oriented series (such as the series) it advises. This
means that securities are selected based upon fundamental analysis (such as
an analysis of earnings, cash flows, competitive position and management's
abilities) performed by the series' portfolio manager and MFS' large group
of equity research analysts.
The series is a non-diversified mutual fund. This means that the series
may invest a relatively high percentage of its assets in a small number of
issuers.
The series may invest in foreign securities (including emerging markets
securities) through which it may have exposure to foreign currencies.
The series may engage in active and frequent trading to achieve its
principal investment policies.
o PRINCIPAL RISKS OF AN INVESTMENT
The principal risks of investing in the series and the circumstances
reasonably likely to cause the value of your investment in the series to
decline are described below. The share price of the series generally changes
daily based on market conditions and other factors. Please note that there
are many circumstances which could cause the value of your investment in the
series to decline, and which could prevent the series from achieving its
objective, that are not described here.
The principal risks of investing in the series are:
o Mid-Cap Growth Company Risk: Prices of growth company securities held by
the series may decline due to changing economic, political or market
conditions, or due to the financial condition of the company which issued
the security, and may decline to a greater extent than the overall equity
markets (e.g., as represented by the Standard and Poor's Composite 500
Index). Investments in medium capitalization companies can be riskier and
more volatile than investments in companies with larger market
capitalizations.
o Over-the-Counter Risk: Over-the-counter (OTC) transactions involve risks
in addition to those associated with transactions in securities traded on
exchanges. OTC-listed companies may have limited product lines, markets
or financial resources. Many OTC stocks trade less frequently and in
smaller volume than exchange-listed stocks. The values of these stocks
may be more volatile than exchange-listed stocks, and the series may
experience difficulty in establishing or closing out positions in these
stocks at prevailing market prices.
o Foreign Markets Risk: Investing in foreign securities involves risks
relating to political, social and economic developments abroad, as well
as risks resulting from the differences between the regulations to which
U.S. and foreign issuers and markets are subject:
> These risks may include the seizure by the government of company
assets, excessive taxation, withholding taxes on dividends and
interest, limitations on the use or transfer of portfolio assets, and
political or social instability.
> Enforcing legal rights may be difficult, costly and slow in foreign
countries, and there may be special problems enforcing claims against
foreign governments.
> Foreign companies may not be subject to accounting standards or
governmental supervision comparable to U.S. companies, and there may
be less public information about their operations.
> Foreign markets may be less liquid and more volatile than U.S.
markets.
> Foreign securities often trade in currencies other than the U.S.
dollar, and the series may directly hold foreign currencies and
purchase and sell foreign currencies through forward exchange
contracts. Changes in currency exchange rates will affect the series'
net asset value, the value of dividends and interest earned, and gains
and losses realized on the sale of securities. An increase in the
strength of the U.S. dollar relative to these other currencies may
cause the value of the series to decline. Certain foreign currencies
may be particularly volatile, and foreign governments may intervene in
the currency markets, causing a decline in value or liquidity in the
series' foreign currency holdings. By entering into forward foreign
currency exchange contracts, the series may be required to forego the
benefits of advantageous changes in exchange rates and, in, the case
of forward contracts entered into for the purpose of increasing
return, the series may sustain losses which will reduce its gross
income. Forward foreign currency exchange contracts involve the risk
that the party with which the series enters the contract may fail to
perform its obligations to the series.
o Emerging Markets Risk: Emerging markets are generally defined as
countries in the initial stages of their industrialization cycles with
low per capita income. Investments in emerging markets securities involve
all of the risks of investments in foreign securities, and also have
additional risks:
> All of the risks of investing in foreign securities are heightened by
investing in emerging markets countries.
> The markets of emerging markets countries have been more volatile than
the markets of developed countries with more mature economies. These
markets often have provided significantly higher or lower rates of
return than developed markets, and significantly greater risks, to
investors.
o Non-Diversified Status Risk: Because the series may invest its assets in
a small number of issuers, the series is more susceptible to any single
economic, political or regulatory event affecting those issuers than is a
diversified series.
o Active or Frequent Trading Risk. The series may engage in active and
frequent trading to achieve its principal investment strategies. This may
result in the realization and distribution to shareholders of higher
capital gains as compared to a fund with less active trading policies,
which would increase your tax liability. Frequent trading also increases
transaction costs, which could detract from the series' performance.
o As with any mutual fund, you could lose money on your investment in the
series.
An investment in the series is not a bank deposit and is not insured or

government agency.

The bar chart and performance table are not included because the series
had not commenced investment operations as of December 31, 1999.

"(16) INVESTMENT RESTRICTIONS THAT APPLY ONLY TO THE GLOBAL
TELECOMMUNICATIONS SERIES AND THE MID CAP GROWTH SERIES:
The Global Telecommunications Series and the Mid Cap Growth Series may
not:
(1) Borrow amounts in excess of 33 1/3% of its assets including amounts
borrowed.
(2) Underwrite securities issued by other persons except insofar as the
Series may technically be deemed an underwriter under the Securities
Act of 1933 ("1933 Act") in selling a portfolio security.
(3) Issue any senior securities except as permitted by the 1940 Act. For
purposes of this restriction, collateral arrangements with respect to
any type of option (including Options on Futures Contracts, Options,
Options on Stock Indices and Options on Foreign Currencies), short
sale, Forward Contracts, Futures Contracts, any other type of futures
contract, and collateral arrangements with respect to initial and
variation margin, are not deemed to be the issuance of a senior
security.
(4) Make loans to other persons. For these purposes, the purchase of
short-term commercial paper, the purchase of a portion or all of an
issue of debt securities, the lending of portfolio securities, or the
investment of the Series" assets in repurchase agreements shall not
be considered the making of a loan.
(5) Purchase or sell real estate (including limited partnership interests
but excluding securities secured by real estate or interests therein
and securities of companies, such as real estate investment trusts,
which deal in real estate or interests therein), interests in oil,
gas or mineral leases, commodities or commodity contracts (excluding
Options, Options on Futures Contracts, Options on Stock Indices,
Options on Foreign Currency and any other type of option, Futures
Contracts, any other type of futures contract, and Forward Contracts)
in the ordinary course of its business. The Series reserves the
freedom of action to hold and to sell real estate, mineral leases,
commodities or commodity contracts (including Options, Options on
Futures Contracts, Options on Stock Indices, Options on Foreign
Currency and any other type of option, Futures Contracts, any other
type of futures contract, and Forward Contracts) acquired as a result
of the ownership of securities.
In addition, each Series has the following non-fundamental policies which may be
changed without shareholder approval.
The Series will not:
(1) Invest in illiquid investments, including securities subject to legal
or contractual restrictions on resale or for which there is no
readily available market (e.g., trading in the security is suspended,
or, in the case of unlisted securities, where no market exists), if
more than 15% of the Series" net assets (taken at market value) would
be invested in such securities. Repurchase agreements maturing in
more than seven days will be deemed to be illiquid for purposes of
the Series" limitation on investment in illiquid securities.
Securities that are not registered under the 1933 Act and sold in
reliance on Rule 144A thereunder, but are determined to be liquid by
