First Covid-19 shot

Link to your "fact" protection goes to zero please .
I believe that figure is, - "drops below" 90%ish (?).

TE="bcschief, post: 1973548646, member: 13460"]They are finding that people that got the vaccine when it was first available now need a booster shot because there antibody levels are back at zero so it is only going to cover you for about 6 months. Haven't heard any studies of what amount of time having COVID will prevent you from getting it again.[/QUOTE]
