U.S. colleges hoping for a return to normalcy next fall are weighing how far they should go in urging students to get the COVID-19 vaccine, including whether they should, or legally can, require it.

Some have already said students will have to get shots before returning to campus, including at Rutgers, Brown, Cornell and Northeastern.

VACCINE INFORMATION: Check to see if you are eligible

APPOINTMENT INFORMATION: Where and how to get vaccinated

They say they will help protect their campuses and give students the confidence to return. But some schools say they cannot legally require vaccinations because the U.S. Food and Drug Administration has only allowed the emergency use of COVID-19 vaccines and hasn’t given them its full approval.

Still, other colleges are opting to recommend shots without requiring them.
