That goes both ways.
How so?
Because you’re pushing medical intervention on me for your benefit that could be harmful to me. So you should also contemplate the moral issue of possible self interest vs. the potential to be the cause of harm to others.
It is an obligation to listen to the doctors (Maharik Shoresh 159, Shevut Yaakov 1:65, Yalkut Yosef Kitzor Shulchan Aruch Laws of the Doctor and the Obligation to be Cured 2). As this is a public health matter it would seem that he authorities should compel parents to vaccinate their kids.If they do not are their kids become ill they would chayavim b’dinei Shemayim (as it is gramma).
Presumably that is talking about where the doctors are acting responsibly and giving you medical advice that is appropriate to you. In this case, the doctors are giving you medical advice that is not appropriate for you (or at least they haven’t even contemplated whether it is), for the benefit of other people.
