I think the need for boosters is based on both the mutation rate and the general lack of long term human human immunity to coronaviruses as seen in various cold viruses.
Plus they don’t know what they don’t know. This coupled with the bureaucratic risk aversion is how we’ve ended up with these stupidly excessive “abundance of caution” masks and lockdowns.
I’ve gotten quite sanguine with the doom Karens. Fauci has pretty much been wrong about everything since the 80’s. He’s unlikely to start being correct now.
Agreed on Fauci and the doom Karens.
As for the boosters, I just don’t know. I have some educated guesses. Maybe because of mutations, but then they really should be a little more upfront about it instead of letting drug company CEOs disclose it. I also suspect the possibility that because mRNA vaccines have been a 15 year disaster, that whatever concoction they have come up with is incredibly weak stuff in order to not kill we humans the way they killed rats, rabbits and chimps in all the previous iterations - and hence the need for 2 shots instead of just one. But just guesses. I really don’t know, and don’t like that they don’t tell us.
