Goes like this:
I have a right to decide what happens to my children!
To that I say, we have the right to not be a victim of your stupidity. Further, laws represent social contracts that all members of society enter into for everyone's benefit. Getting vaccinated is one such contract which serves to prevent epidemics of infectious diseases.
If you really don't want to vaccinate your child, then please ensure your child never comes into physical contact with the rest of society for our sake. I would not welcome them without vaccinations.
