In the 4th grade none of us kids had a choice, they vaccinated us all and our parents didn't know until we came home with a big sore on our upper arm that scabed and leaves the tale tell scar.
Otherwise today, because of law suites they don't try such crap and leave it up to each family you comply or supply the secretive paper exemptions. Noneof our kids have been vaccinated nor has my wife. I on the other hand had them all.
