I’m confused. I thought vaccinated people can spread the virus. Why are they not locked down too?
Because the risk of transmission is understood to be significantly lower, and since unvaccinated people are more likely to cause the virus to mutate it's in the governments best interest to get people vaccinated, a way of accomplishing this could be making life inconvenient for the uncompliant.
If you understand natural selection, then this assertion makes zero sense. Where in the genome do we see the accumulation of mutations in all covid variants seen so far? In their S-protein. Where does Omicron have 30+ mutations? In its S-protein.
What is the single protein that the mRNA vaccines code for??
Yes, if you reason from first principles, it is trivial to see that it is in fact the throngs of the vaccinated who are driving the evolution of SARS-CoV-2!
