This has already happened. The FDA has given permission for doctors to give their patients booster shots from another vaccine manufacturer. In other words, if the first shot doesn't get you then the other one definitely will. They are doing everything to make sure everyone gets sick from these shots with whatever illness it is vaccinated people will eventually develope.... I think it's an early death. We already know Biden has advisors who are on record as saying people are living too long.
The F.D.A. may authorize booster shots of vaccines different from the ones that Americans originally received. The science behind the move is promising.
