Just saw a post from a very vaccinated liberal Jewish Facebook friend (even her kids are vaxed) exhorting people to "make sure to get your shingles vaccine," because she got it.
Shingles is iirc just latent chicken pox that your body normally knows how to handle when the immune system is on point.
My mother in law has recently contracted shingles as well. I know I'm a little late on this one but I was reading this article on the Donald about how the pattern seems to be that the double / triple vaxxed end up getting covid / variation of SARS and then the problems start.
This is how it happened for the MIL, had a few days of run down / fatigue / and I can't remember how long after, hello shingles. I don't remember when she got her shots, but she works @ one of the hospitals here, so it was that or her job.
Over this past weekend, a close contact had basic flu / cold symptoms out of the blue. Has continued to have a headache. This person got their 2nd shot in November.
