Purely anecdotal story, but I will share:

This week was the first time I have gotten COVID, and it hit me pretty hard. Admittedly I have not been especially careful in trying to prevent myself from getting it, so for a while I wondered if I only got it asymptomatically or if the vaccines (I got the OG one plus two boosters) were enough to not get a serious infection.

I sort of wonder if there was a mutation that has evaded the vaccines, and that is what is going around?
