Some jobs also require vaccination updates.

Mostly yes. : As with the freedom of speech, you can say almost anything you want and be protected as an american. In most instances, vaccinations can be avoided by a religious objection, but what kind of religion would allow its children to be at risk for death from preventable diseases?
