They can't quarantine towns from the federal level. Not in the least. A state might be able to, because the 10th amendment is a thing, but Federal government cannot. And neither state nor federal government can force vaccines because it violates the 4th amendment. You don't get to search my body for diseases and use them to discriminate against me. Sorry. Furthermore, Roe v. Wade was argued on the basis of a right to privacy that's implicit. So no, I'm right on this.
