Note that natural immunity provides even more pressure to mutate because it's likely to be targeted against more unstable parts of the virus. We are already seeing this in action--while natural immunity provides very good protection against reinfection *with that strain* it doesn't do so well against other strains. The good vaccines (not the killed-virus Chinese garbage) deals with variants better than prior infection.

And the vaccine *does* provide protection against Delta--you're less likely to get it and if you do get it it generally is less serious. Being vaccinated cuts your death rate 10x.

Natural immunity isn't going to happen, we have seen far too many cases of reinfection with different variants. The more we see the more hopeless the death cult approach looks.
