>I think that the opposite is true - the vaccines have not been deployed fast enough around the world and this has allowed new more infectious variants to emerge.

Or, the incredibly narrow focus of the mRNA vaccines put enormous evolutionary pressure on the virus to mutate.

All too often you hear the misconception that only the unvaccinated can act like a petrie dish for mutations, but this can happen just as easily in anyone vaccinated.

Now how many people where there vaccinated with mRNA vaccines in South-Africa?

I propose that if there would have been more, we would possibly not have this variant. We do not see new variants popping up in highly vaccinated areas.
