Last year I was told that we were at risk of, or no longer had, herd immunity due to that. I don't recall if it was specific to our university, city, or other geographical region.
I stopped getting the flu shots in my 20s because I would always get sick despite the shot. I was convinced in my mid-30s to start getting them again. I still get sick, but it's not as bad as when I skipped the shots.
(I know at least a couple times I ended up getting the shot that prevented a variant that we didn't get. There's enough of a time gap that the shot isn't causing the symptoms.)
