text_2: "Besser said, ""It used to be that the only children at school who weren't vaccinated were those who had true medical"" conditions, but ""now there are 19 states that allow personal belief exemptions."" Besser, a pediatrician, is right about the number of states that allow exemptions to state vaccination laws for personal beliefs. But his history lesson about vaccination laws of yesteryear is not as accurate. States have consistently provided religious exemptions alongside medical exemptions, and five predominantly Midwestern states allowed parents to seek exemptions for any reason even in the 1960s. His claim is partially accurate. Clarification: This post has been updated to better reflect how Elena Conis said the modern anti-vaccine movement began."
