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.
Got a vaxed friend who got the shingles. Then another friend on FB, big vaxed, today said she had the shingles.
Getting your Cd8 tell count dropped does that to a person.
