Expects Yuge Games
So this virologist that won the Nobel prize doesn't know how mutations occur?
I'm not going to say he is ignorant of this. But I believe I'm correct in saying that mutations arise randomly during replication. The process that drives the emergence of mutations is the same with and without vaccines.
Some variants may develop that are more resistant to a particular vaccine. If that vaccine didn't exist we would not be aware of this. It would be just another variant. But if a vaccine exists that particular variant will get more attention.
