1 was hit before the vaccinations were even available... so I think that was Alpha or Delta and he's still struggling 2 years later. He was super crazy fit as well and isn't able to work yet. 2 (a couple) were both vaccinated and boosted - and neither can run at all now (but both are back at work) but I guess comparatively it's only been 5ish months.
It sucks that you've had such a rough go of it. I hope, against all the odds, you're around for a long time teaching your daughter all the things. You seem like you'd be a decent teacher.
It is a strange one. I think there are more factors than fit or not and suspect there is some kind of "marker" that determines severity. I know some fit people who suffered, some very unfit who had it mild. I think it is the same for the vaccines, as people's bodies react differently to the whatever is in it. My wife is still having issues after being vaccinated mid-last year. This is her first bout of covid.
I am not planning on checking out too early - but I am preparing, just in case :)
