I have wondered if those vaccinated produce the same T cells as those infected, suspecting not because the current COVID shots only target one spike protein. I’m becoming more convinced Original Antigen Sin holds the answer. 1/ #COVID #vaccine en.wikipedia.org/wiki/Original_…
If so, has the vaccine removed the body’s ability to effectively fight variants without one-off boosters targeted to the dominant strain? That circumstantially fits with what’s happening today. /2
“But when [the immune system] encounters the same infection, at a later evolved stage, with a new dominant antigen, with the original antigen now being recessive, the immune system will still produce the former antibodies against this old "now recessive antigen" /3
and not develop new antibodies against the new dominant one, this results in the production of ineffective antibodies and thus a weak immunity.” /4
