Vaccine Exemptions

It is law in all US states that children be properly immunized before attending school. However, in addition to medical exemptions offered in each state, the vast majority of states allow for religious exemptions and various states allow personal belief exemptions for daycare and school.

School Exemption Laws by State

Some state laws specify religious in addition to personal belief exemptions; other state laws do not. However, in practice, states that offer personal belief exemptions also allow for religious exemptions as part of the personal belief exemption (Minnesota and Louisiana, for example).
