I can't really argue that aids treatment isn't better, but by around the 2000s it was a single pill, and Aids is also something we learned how it spreads and could massively reduce the risk of, which is not true for any of the new problems.
We have never had the head of the fda being antivax and actively cutting vaccine programs. About 20% of Republicans are antivax, and the majority of Republicans do not think vaccinations are important. And yes, that's sort of what I mean, we're going back to 1880s levels(if not worse) of "vaccines are unsafe," despite 140 more years of research showing that they are unbelievably safe. That level of anti-science isn't unprecedented, but it's far far worse than when I was growing up. This is not contained to just the US either, but the US is the most extreme case.
