TLDR: the polio vaccine used to contain weakened versions of the three strains of poliovirus. When weakened live virus vaccines are used, the people inoculated with them shed copies of those viruses, which is usually no big deal… except that one of those weakened polio strains would, very rarely, mutate back into its full-strength form and sicken unvaccinated people living around those who were being vaccinated.

Eight years ago, the decision was made to remove the problematic strain of polio from the vaccine, because it was thought low wild infection rates meant that the risk of vaccination-derived infection had become higher than catching it from the environment. Regrettably, it seems that decision was made in error – type 2 polio outbreaks have soared since then.

Somewhere a philosophy undergrad just sat bolt upright and shouted, “A TROLLEY PROBLEM! I must go, the world needs me!”

Alas, I was so looking forward to hearing them parrot the talking points of acclaimed Leninist… (checks notes) … JD Vance.

With regard to this specific issue, you don’t even have to go looking for cases of young women being discouraged from reporting rape and sexual assault allegations against promising young athletes, because “think how you could hurt his future prospects” – examples are so plentiful that you can’t help but find them if you spend any time reviewing sports news. It’s really only been in the last decade or so that anybody has seriously pushed back against the idea that Johnny Sportsball’s ability to score points for the local team is more important than the safety and bodily autonomy of women.
