> How about 5yrs from now, will the 17th booster shot still be as affective? ...yes? Why wouldn't it be? (Although I truly can't imagine any scenario where you end up with so many booster shots, only the flu is like that and it's a different shot every year, because the flu is a very unusual virus.) |
