Curious as to your epidemiological background. I have absolutely none at all, but reading those who have it in abundance seem to be very much in agreement that further mutating is *not* what anyone wants, hence the need to "vaccinate the world" (and not just us rich folk).
I wear a mask to protect other people because, just a few weeks ago I was walking around infected and infectious and had no idea. Fortunately I'm largely a hermit and the few occasions I was in enclosed spaces with others, I dutifully masked up, and this was before the reimposition of masks. It may just have kept someone out of hospital or even saved a life. There's no way of knowing that, of course, but it was certainly a positive for those I met that I was wearing a mask at that time.
You’re probably right.
