I don't think arresting people is a good solution, for sure - as usual, when parents are nitwits, the children suffer the consequences.

But with the continuing rise of woo - anti-vaccine zealots, homeopathic 'medicine' and other bits of quackery, something should be done to try to protect these children and their peers.

The question is, how many unvaccinated kids are there, and how many does it take before they are seriously at risk of having their own little epidemic?

I was hired a while back to proof, edit and update a collection of genealogies from one area, going back more than 200 years. When diptheria raged through the community in the early 1900s, the results were obvious and heartbreaking. Families lost one, two, three, sometimes all of their children in less than a month. Each epidemic of scarlet fever, whooping cough, measles, diptheria, left its mark in the records, a sad list of dead children.
