Your child being vaccinated against measles is 1. yes, protecting them, but 2. also protecting all the other children at school they interact with, and vice-versa. It isn’t just an individual choice. You should definitely fault people for going the other direction because they are willingly increasing the chance of your child or your child’s friends getting measles.

The US sees in the ballpark of a hundred million tourists, business travelers, and migrants per year. And these people are vectors for basically everything and are numerically very large. And you're inevitably going to bump into and interact with these people. So I think the idea of domestic herd immunity is increasingly nonsensical because 'domestic' is no longer even remotely close to a closed system. And global herd immunity is nonsensical simply because it's wholly unrealistic, and at that sort of scale any small issue can explode into a huge one: see - source of most modern cases of polio.

American exceptionalism at its finest!

You do realise the vast majority of those "tourists, business travelers, and migrants" are all fully vaccinated?
