Do me a favor. Please, please. If you can, and you haven’t yet, go get a Shingrix vaccination. The old shingles shot is so much less effective, and the Shingrix one so much more so and with so few complications, that the old one has been taken off the market.
The old one is what my friend had had, and she is back in the hospital today.
I’d never heard of shingles in the brain.
(Late update: they now say en route to, not in the brain. Yay.)
