That’s actually the entire reason behind the thrust, and is quite well known.
Covid doesn’t mutate in vaccinated people. But it does mutate in the unvaxxed.
The next mutation of concern might be one that evades all the vaccines and we would be back to ground zero.
Covid doesnt mutate in the vaxinated? You are either dumb as a stump or well... yes dumb as a stump. Covid almost exclusively mutates in the vaxinated.
Little biology lesson for you. The vax is semi effective. People still get infected. Any mutation that allows the virus to get around vax is the type the body sheds because the mutated type is the one of predominance. In an unvaxed person the one of predominance is the one they caught. There is no pressure (reproductive benefit) to mutate. Bottom line: The vaxed are walking talking spreading variant factories. The unvaxed are sick at home and recover in about 99.75% of cases to never catch or spread it again because of persistent TCell immunity. Their TCells key on the 25 or 26 total proteins of the virus so they are largely variant immune. The vaxed antibodies key on 1 protein and antibodies fade in 6+ months.
The best thing we could do is to stick all the vaxed together and let them infect each other and recover and get TCells so that we can actually have herd immunity.
