What does this mean? IMHO it means that once we reached sufficient levels of vaccinations (no idea what that would be, definitely above 70%) COVID will be nothing more than a severe flue / cold for most of the population, if they get it at all. It would also, I would assume, push mutations down the more infections and less severe route in order to overcome the limited spread among the vaccinated (they are still overall less infectious then unvaccinted people) and the vaccines themselves. Both are good news.
And that drives me so crazy with the anti-vaxxers (among a lot of things with them). They don't want the shots because a) COVID is just a flew (and simultaniously a deadly bio weapon the Chinese spread in order to win a global economic war...) and b) vaccinated people are also infectious and can get it. Well, they kind of have it backwards there, don't they? it actually will be like a cold because people are vaccinated, not before. At which point the fact that vaccinated people can also transmit COVID is not really important anymore.
