VERY reasonable and helpful article!
“Wild” infections are a significant factor in “herd” immunity.
His suggestion to concentrate on vaxxing uninfected is reasonable. Though now “wild” immunity gained last year may be fading.
The problem is finding out if one has indeed been previously infected. In my experience that is problematic in the US (making appointments require you to present a lot of personal data), though the UK may make it easier.
Wish the study had also looked at “severe” infections.
“ Though now “wild” immunity gained last year may be fading.”
Doubtful.
T cell protection lasts. In any population in the entire world, I’ve not read of more than 20% (and usually less) getting the covid.
Even among the Diamond Princess cruise ship, less than 20% were infected.
I think people with T cell immunity are barely affected.
But it “perfects” their immunity to this covid virus, and spreads herd immunity.
