"In mice". And, the effect size is pretty small. The largest effect size I know of, predicting incidence of real dementia in real people (46,000 people over 70), is that a recent Tdap booster predicts a 40% reduction. Nobody knows how or why, or isn't saying. Apparently treatment for herpes has a large effect size, too. It is easy and safe to get both.
