Could it really be a precedent when polio vaccines have been mandatory in all states for generations of children. Suggest we're just making up what authoritative idea would be considered a precedent.

Typically you regulate the intermediary instead of regulate the individual, ie school admission requiring it, military service requiring it, travel requiring it etc.
