Interesting UK study that showed the shingles vaccine may protect someone from (some) cognitive decline.

the study author admits that there could be a study bias in that someone who seeks out the vaccine may overall be healthier when compared to the general public. For the control group who did not have the vaccine, it was not necessarily their choice but rather they didn’t meet the eligibility for the vaccine. UK socialized medicine. Therefore this isn’t necessarily vaxxers vs anti-vaxxers.
And for anyone here 50+ who hasn’t had the shingles vaccine, ask someone who had an episode of shingles for their view. Shingles and its vaccine is not like skipping the flu shot and getting the flu. As a warning, I know some have bad reactions to the shingles vaccine. I was lucky to avoid it.
