The most astonishing recent news about dementia surfaced in April, here on HN: A recent Tdap vaccination correlates very, very robustly with a 40% reduction in dementia risk (doi:10.1093/gerona/glab115).
Nobody knows how to interpret it. 40% is a huge effect size! (I doubt aspirin shows up as more effective against headache.) Is it the tetanus, the diphtheria, the pertussis antigen? Something else they put in the vaccine?
You can get a Tdap at any pharmacy, on demand. I did.
