Does each time a person gets covid after a vaccination mean that that this particular virus subset has mutated a little bit to survive? And potentially become a killer strain to everyone else, if it breaks out?
Curios.
“Mutation” of a virus happens everytime it replicates. Replication or copies are never perfect, and nearly never increase the deadlines of a virus. They use the word mutation to scare everyone, but everyone seems to forget that the mutations lessen lethality. It is in the viruses interest to become less deadly, so its host can live and hopefully pass it on.
