Control over our own bodies is the most sacred individual right.
For kids in schools and vaccines, there is a choice. The choice is for the parents. They can choose to vaccinate junior and send him to public school or can choose private education or homeschooling where it isn't required.
For members of the military, one can choose to join or not (thank Zeus the draft is inactive).
It is you who is contorting our founding laws, not me.
