A few findings from the writeup that surprised me:
- Adult vaccines don't extend lifespan beyond protection from the disease on the label.
- They do cut dementia rates by 20%+, in the cleanest natural experiment we have.
- The same effect shows up across nearly every adult vaccine, including ones for diseases basically nobody in the developed world catches.
- So it's not the vaccine doing its labeled job. It's trained immunity — the immune system doing better housekeeping (clearing senescent cells, amyloid, tau).
