Pointing to bodily integrity rights and claiming he’s facing unconstitutional coercion, a George Mason University law professor is suing university officials to block a policy requiring students, faculty and staff to get the COVID-19 vaccine before returning to campus.

The lawsuit lodged by Antonin Scalia Law School Professor Todd Zywicki centers on the argument that he has already “acquired robust natural immunity” from previously contracting COVID-19 and that his immunologist has “advised him that, based on his immunity status and personal medical history, it is medically unnecessary to undergo a vaccination procedure at this point (which fact also renders the procedure and any attendant risks medically unethical),” according to the complaint.
