I asked this very question and got brigaded by people saying that they’re exercising their rights and other such nonsense. A lot of people there don’t seem to understand that the right to life comes above whatever rights you feel like exercising for your own selfishness.
American here, they’re also wrong. The Supreme Court itself a long time ago has set the precedent that mandatory vaccinations for the public good in a health crisis are constitutional. These Trollops are bitching about rights they actually don’t have.
