I see. It may be true that communities that were not careful were more exposed at the beginning, had very high rates then, and lower rates later. I don’t think it gave any overall benefits though, unless older people were strictly isolated. More than 50% of transmissions happen in the family, so if kids got it, they will transmit to parents and then to grandparents.
But your observation highlights importance of the discussed question whether previously sick require a vaccine, especially if those sick were in the early months and now more than a year passed and new variants are around, so some people might think that they are still protected when they are not.
and there is probably a positive correlation between those who were not careful l’hathila and got sick and vaccine hesitancy, so this cluster – sick early and not vaccinated – is one to watch for increase in disease, and, presumably, recommend to take one does of mRNA or JJ.
