The University of Notre Dame will require that all students get a COVID booster for the spring semester.

That’s according to an email from the Division of Student Affairs. The Observer reports that the decision comes with a deadline of mid-semester. The email says the school will offer a vaccination clinic with Pfizer-BioTech at the Joyce Center from January 11th through the 14th. Students will need to register in advance.

The requirement includes all undergraduate, graduate and professional students as well as those studying or conducting research abroad. Those who were exempt from vaccines will also be exempt from the booster requirement.
