What's this obsession of anti-anti-vax with measles? When I was on my national Reddit sub, it would come up 40 times a year.

When I was a kid, everyone was catching it. That was just one of those diseases you catch once and then you are done with it.

It is so low-risk that doctors didn't even declare the cases as they were supposed to be. They just observed them in case it would turn bad. Watching well and treating the few difficult case well made it so that there was just around 5 deaths a year, amongst cohorts of 800.000 who almost all caught it. At the scale of my department, that would be one letal case every 80 years... Outdoor leisure kill more in half a week here, as it was noticeable after lockdown (as we were very lucky with Covid, there were more outdoor leisure related death in 4 days of reopening than Covid related death from 9 months of first wave. NB: it was unfortunately different with second wave)

In the decade immediately before the measles vaccine was distributed in the US, an average of 495 deaths per year and 1000 people severly disabled (1). In modern per-capita US terms, that would be like 866 deaths (mostly children) and 1750 disabled. While that's not much compared to COVID, it is about 1/6 as many deaths as polio in its worst year in the US, and that was a widely feared virus.

The Measles vaccine is also a proxy for other behavior. Minimally, in the US, folks that aren't innoculated for measles probably aren't innoculated for mumps or rubella (as MMR is one vaccine), or other important vaccines altogether.

There is also the sick irony (no pun intended). The anti-vaxers are preventing a phase out of a vaccine by their actions. If measles got nationally eradicated or better yet internationally (a slow laborious process sadly) - it would mean fewer vaccines because it did its job perfectly.
