Doomsday:
Vaccinator: No, you don’t have the right to decide what you do with the bodies of your children.
Vaccinator, who does get to make medical decisions for our children? The Parents or The Government?
The answer is: The Torah, parents, and the government. It is most definitely NOT just the parents- as I said, you do NOT own your children. And we know that if parents are not being responsible in caring for their children, the children will be taken away. That is the responsibility of a society (ie, government). You can’t throw your children out the window even if in your warped mind you think that’s best for them. The Torah tells us we need to follow the majority and we need to take care of our bodies – and the Halacha gives great priority to doctors’ opinions. It is nearly unanimous among doctors that vaccinations are required (in spite of all your speculations about how many doctors feel “deep in their hearts but not willing to say it publicly” that they don’t believe in them). So, yes, in this case, those who know better than uninformed parents like your anti-vaxxers (and all your posts have shown that you are very very uninformed) are nearly unanimous in their opinion, yes, we are required to listen to them.
And, in more direct response to your question (who gets to make the medical decisions for our children), if we are talking about parents like you, then government (or just about anyone else) is in a better position to make responsible, caring decisions for the children, rather than having you follow a personal agenda and philosophy that has nothing to do with caring about the children but rather simply fighting the establishment like the 1960s hippies. If you care about your children, you’ll get them vaccinated as soon as possible. You’ve lost the argument.
