alt Hacker NewsArticle specifically refers to vaccination with live attenuated virus... Should a difference be inferred between Shingrix and Zostavax (in the context of the effect on dementia, not shingles)
Background to the question is providers here seem to be switching to Shingrix for (claimed) higher effectiveness against shingles, but there's at least some suggestion that Shingix is not live (attenuated) virus...
From https://www.ox.ac.uk/news/2025-06-25-how-do-vaccines-reduce-...
> The shingles vaccine now in widespread use (Shingrix) has more of an effect than the previous one (Zostavax). A key difference between these vaccines is that Shingrix contains an ‘adjuvant’, an ingredient designed to enhance the vaccine’s effect. It is therefore possible that the adjuvant contributes to Shingrix’ greater effect than Zostavax on reducing dementia.
