Is it analogous to flu? Do flu vaccines cause mutations as well? One interesting thing about covid is that it seems to be the first time humanity has collected so much data (eg. contact tracing, phylogenetics through genome sequencing, etc.) about this kind of virus, and applied modern medical knowledge in trying to combat it. It's very apparent that the overall response hasn't been nearly good enough, but it's probably also the best response there's ever been. (perhaps not the best ROI, though?)
