To be fair about vaccines there a lot of people who do "bat an eye" as it were. While (in my state at least) vaccinations are not exactly a law so much as they are a "recommendation" by the CDC., but places like schools and Dr.'s offices will refuse your child if they aren't vaccinated. A lot of parents choose not to vaccinate and get a lot of heat for it from schools and Dr.'s about it but there are no legal ramifications.
