Again: Viruses do not necessarily evolve to be milder—especially if they transmit early, like this one. Our immune system learning about it—via vaccines or infection—can mean better response next time, so milder experience. Not same as virus becoming intrinsically less virulent.https://twitter.com/zeynep/status/1465075561236250631 …

False. Vaccine kills it much faster than the naive immune system and thus gives it less scope for mutation. A long illness (frequent without vax) is worst case scenario because it gives weeks of mutation potential.

There is good evidence high vaccination rates do drive viral evolution, reducing the number of variants while selecting for the more transmissible variants. This may not be a bad thing, but it’s certainly happening.https://www.medrxiv.org/content/10.1101/2021.07.01.21259833v1 …

I find it intensely amusing when someone tells me that something which is already happening, and is well-documented, is impossible.
