I ask because at one of our elementary schools, whooping cough is going around. One of the parents decided to put off immunizations (I am not sure how she got away with it, but I know you can claim certain religious objections and other things). The school had to be shut down, all the kids put on medication that can cause bad side effects, and I believe the kids all have to be immunized over again, but I'm not sure about that. This is my opinion: If you are afraid of immunizations then homeschool. There is no evidence that shots cause autism, although I know some parents still insist they think it does. I've even heard people say that there is no autism in the Amish community because they don't immunize. I live near the Amish. If a child was autistic, nobody would know. They don't utilize school and community services and don't go to doctors for things like that. So I doubt there are no autistic Amish kids. Back to the original question: Should parents be allowed to opt out of immunizations and still expose their kids to other kids at public schools?
