(MyNorthwest photo) Many colleges and universities in Washington state have announced that the COVID-19 vaccine will be required for students when they return to campus in the fall, at both public and private colleges. Is any of this legal, and if it is, under what authority? Former Washington Attorney General Rob McKenna says it appears public colleges can mandate these vaccines, but it hasn’t yet been tested in court. “There are arguments being made right now by plaintiffs who have lost their jobs because they refused to become vaccinated, that approval of these vaccines under emergency use authorization isn’t sufficient,” McKenna told the Jason Rantz Show on KTTH. “The problem they have in those lawsuits, and the problem that a college student would have pushing back against the University of Washington’s requirement, for example, is that the language in the emergency use authorization for each of these vaccines doesn’t speak to employers or to colleges.”
