MFS VARIABLE INSURANCE TRUST
Supplement to Current Prospectus
The section of the Trust's Prospectus entitled "Information Concerning
Shares of Each Series - Purchases and Redemptions" is hereby amended to add
after the first paragraph the following:
At the sole discretion of the Trust, each Series may pay
redemptions either totally or partially by a distribution in-kind of
securities (instead of cash) from such Series' portfolio. The
securities distributed in such a distribution would be valued at the
same amount as that assigned to them in calculating the net asset value
for the shares being sold. Securities distributed by a Fund will be
selected by the Adviser in light of the Fund's objective and may not
generally represent a pro rata distribution of each security held in
the Fund's portfolio. If a shareholder received a distribution in-kind,
the shareholder could incur brokerage or transaction charges when
converting the securities to cash.
The date of this Supplement is November 15, 1997.
