TRANSAMERICA SERIES TRUST

Transamerica Jennison Growth VP

Supplement to the Currently Effective Prospectus,
Summary Prospectus
and Statement of Additional Information

The Board of Trustees has approved a reorganization pursuant
to which the assets of Transamerica Jennison Growth VP (the
"Target Portfolio") would be acquired, and its liabilities would
be assumed, by Transamerica Morgan Stanley Capital Growth
VP (the "Acquiring Portfolio"), each a series of Transamerica
Series Trust, in exchange for shares of the Acquiring Portfolio.
The Target Portfolio would then be liquidated, and shares of
the Acquiring Portfolio would be distributed to the Target
Portfolio investors.
Under the reorganization, Target Portfolio holders would
receive shares of the Acquiring Portfolio with the same
aggregate net asset value as their shares of the Target
Portfolio. The proposed reorganization is not expected to
qualify as a tax-free reorganization for Federal income tax
purposes.  Holders of annuity and insurance contracts funded
by insurance company separate accounts invested in the
Target Portfolio are not expected to recognize any income or
gain as a result of the reorganization.
The reorganization of the Target Portfolio into the Acquiring
Portfolio is subject to investor approval. A proxy
statement/prospectus describing the reorganization is expected
to be mailed to Target Portfolio investors in September 2019.
If the reorganization is approved by Target Portfolio investors
and all other closing conditions are satisfied, it is expected that
the reorganization would occur in the fourth quarter.  Effective
on or about October 25, 2019, the Target Portfolio will be
closed to new and/or additional investments.  Prior to that
date, investors can continue to purchase, redeem and exchange
shares of the Target Portfolio subject to the limitations
described in the Prospectus and Summary Prospectus.
