Right. Abstractly viruses find a sweet spot between transmission rate and lethality to host. Too lethal and it won’t spread very far. However, in practical terms there is a lot more room for something like COVID to be far more damaging and still spread just like it has been or more. All of the immunity we now have and the particular nature and quality of it will certainly impact what the virus does when mutating. If it really can breakthrough vaccinated populations it’s going to change how it evolves. That is a lot of ifs, buts and maybes. The real world data just is t backing up a lot of these weak claims folks are making. In practical terms the vaccines work and do their job. There is a lot of interesting observations to make and we are in the middle of a great experiment of sorts, so we should be very data driven in my opinion.
