What's the most extreme way the states of the United States can insure compliance to a vaccine mandate for all adults?
Jacobson v. Massachusetts, 197 U.S. 11 (1905), was a United States Supreme Court case in which the Court upheld the authority of states to enforce compulsory vaccination laws. The Court's decision articulated the view that individual liberty is not absolute and is subject to the police power of the state.
Recently, there was a lot of discussions about a possible vaccine mandate and pundits have referred to the Supreme Court case above to make the case that a vaccine mandate in some states would be possible.
There's not a point of common intersection for adults with the state or an agency thereof as there is for children as they all go to school or at least the majority of them. Because of that it's not clear how states can work into a mandate a way to insure compliance, so my question is: what's the most extreme way the states of the United States can insure compliance to a vaccine mandate for all adults?
