I'm one of those people (knock on wood) who never gets sick. I never get colds or seasonal flu, and I don't get routine flu vaccines. Never got COVID either, even when several people in the house had it (I did get the J&J vaccine for that, however).

I did have chicken pox as a kid, but have not had shingles nor the vaccine (yet). A co-worker was laid up for a week after his shingles vaccine, but that's obviously just one data point.

But, I've been considering getting the Shingrix series even if I have to pay for it. I turn 60 this year. Shingles doesn't sound fun.
