This isn’t an easy case to decide.
Unvaccinated kids augment the risk of illnesses for all other kids and adults because the pool that can be infected is greater.
Would you want your child to catch rubeola while you are pregnant? You could then be infected by same rubeola which causes blindness and other illnesses in fetuses? Or your child be exposed to polio because some other child parent has decided he knows best than doctors?
I don’t know.
The point is...do you want government to regulate yet another part of our lives? I for one, do not.
More regulation equals less freedom!
