MFS VARIABLE INSURANCE TRUST
MFS(R)/FOREIGN & COLONIAL EMERGING MARKETS EQUITY SERIES
Supplement to Current Prospectus
As disclosed in the trust's Prospectus, Foreign & Colonial Management Ltd.
("FCM") and its subsidiary, Foreign & Colonial Emerging Markets Limited
("FCEM"), currently manage the assets of the series invested in foreign emerging
market securities, which constitute the primary investment focus of the series.
The following changes will take effect on December 1, 1999:
o MFS will assume all portfolio management responsibilities for emerging
market securities from FCM and FCEM for the series, and the
sub-investment advisory agreements pursuant to which FCM and FCEM
provide their services will terminate.
o The series' name will change to "MFS Emerging Markets Equity Series".
o The description of the manner in which foreign emerging markets
securities are managed, as contained in the Prospectus, will be
revised as follows:
The series is managed by a committee of investment research
analysts. This committee includes investment analysts not only
employed by MFS but also by MFS' foreign advisory affiliates. The
series' assets are allocated among countries and industries by the
analysts acting together as a group. Individual analysts are then
responsible for selecting what they view as the securities best
suited to meet the series' investment objective within their
assigned geographic and industry responsibility.
The date of this Supplement is November 18, 1999.
