As a new semester begins amid a resurgence of the coronavirus, 26 of the 50 largest public university campuses in the U.S. are not mandating that students be vaccinated, according to an analysis by The Associated Press.
Approaches on enforcement vary widely, even among universities that do have vaccine mandates, with some offering leniency for students who opt out and others expelling those who do not comply.
Administrators are emphasizing high student vaccination numbers as key to bringing some normalcy back to campus and keeping instruction in classrooms rather than online.
