"students were being given the impression that the inoculations are compulsory"
I can vouch for this and it's obvious when one reads the language on collegiate websites. Words like "mandatory" sprinkled next to "vaccine" all over the place in order to enroll.
There's some mention of exemptions, but it's not nearly as obvious and I can't tell if every site is the same for every school regarding how they portray the vaccine message.
