Until we can get sterilizing vaccines, I see no viable alternative to periodic non-sterilizing boosters. I think this was pretty obvious when the first vaccines came out and they weren’t sterilizing. Then we have to worry about all the mutations, and if we have to keep getting new vaccines for the new variants, in much the same way as we do flu shots.
