Before it could be administered (assuming it would have been) the vaccine was destroyed by Humanis in The Forever Drug.
About a third to a half of the bequests were followed through over the last fifteen years either intentionally by FASA, e.g. the Dragon Heart, or by random freelancers like me, e.g. having Morgan Leroy Hall collect the last of his bequest while attending Georgetown (Conspiracy Theories) or the Token winners assassinated in Jet Set. The rest were basically left for the players to do with as they wished.
That said, the DF isn't going anywhere, and I have very specific plans for it.
