One of you will end up here next!
Personally, I would prefer to have the opportunity to avoid unvaccinated people in public spaces (see Disneyland measles outbreak for a good reason), but disallowing them at school, where kids are compelled to go daily, is more important to me.
This really has no relevance to the original point that was made, which was that there's no reason to be fearful that your infant grandchild might die, or that they are at any real greater risk of dying, due to a tiny outbreak of measles. Its nonsense, as are all these news stories that aim to scare people about this "deadly disease" by trying to pass off third world statistics as being somehow relevant to care here in the US.
Fifty years ago, before there was a vaccine, we had millions of people infected with measles, and something like 65 infant deaths per year. Now we should worry, because 200 people got measles at Disneyland?
Give me a break.
