Parents Should Have Choice in Vaccinations
In general, there should be no rule that can't be enforced. Parents have the choice as to whether or not their child(ren) are vaccinated. However, it is possible for the school board to enforce rules that determine whether or not a child can enroll in school if a child has not been vaccinated. Also, it is possible for insurance to enforce rules that state how much they would pay if a child is stricken by a disease that could have been prevented by a simple vaccine. Of course, there could be exceptions for children with compromised immune systems.
Also, if it can be proven that an unvaccinated child has sickened other vaccinated children (vaccines aren't 100% effective), the parents should be held liable for the medical expenses of the vaccinated children.
Laws should deal with the consequences of not having a child vaccinated. They shouldn't force a parent to have a child vaccinated.
Hold people accountable for their actions.
