I was chatting with an older fellow who lives in the building the other day, I had been running and was sweaty. He said he'd like to exercise more but had "long COVID", which to me is a thing I'm not very clear about. I infer he had lingering respiratory issues from COVID, or something. I don't know how true all this is, it at times could be a mistake to just be sedentary, or perhaps there are other issues.
Anyway, if it's a real thing, I'd prefer to minimize any risk of it, and risk of COVID itself.
There are two things about vaccinations:
1. The obvious one is protection of the individual to whatever degree,
2. The second is protection of "Society" by cutting down on transmission.
The flu vaccine is mostly recommended because of the second item for younger folks. It's unlikely in a given year a person gets the flu, then it's also just a chance the vaccine prevents the right kind of flu. One can go years without getting the flu. Ostensibly, if we had 100% vax rates, the flu wouldn't persist (if they get the mix right, which is a major variable in itself).
We both got what I think was the flu a few years back and it was quite unpleasant, and we were in Hawaii. Anyway, I sense vax intolerance in the US is at record highs now when it comes to COVID, so the second item above isn't going to work well at all.
