I've had five shots, plus covid once. My doctor thought the last round of recommended booster for seniors was overkill, but I'll probably get a booster this fall along with the flu shot if that's what's recommended. I had a vaccinated friend get pretty sick from covid this spring, so it's not over and I don't think the vaccination protection lasts forever. It's not ever been a big deal to get the shot.
When I had covid about a year ago the recommendation was to isolate for five days and mask for another five. Some of the newer more liberal recommendations don't make a lot of sense to me.
