Vaccinate!!!

When I moved across country, one of my first stops was to update all vaccines for both myself and my son. I'm old enough to have known people who were living with the effects of the diseases

This is a significant and growing problem in the US. In my community about a third of all students in private schools are not vaccinated due almost entirely to religious exemptions (plus a few medical exemptions, though I'm not sure what those are exactly). By contrast the public schools here exceed the 95% vaccination rate deemed necessary for "herd immunity".

In large measure because of lax enforcement and readily issued exemptions like these, we have measles making a comeback in my state.

This is, for once, an anti-science stance that tends to infect liberals as much or more than conservatives, although the religious exemptions are probably mostly conservatives. For liberals it is more commonly the conspiracy theories about mercury-based preservatives in the vaccines causing autism. That is no less stupid than the conservative anti-science stuff like opposition to teaching the theory of evolution.

Maybe the reasons are stupid to us but not to them. They are just worried that is why they don't want to do it.
