At least a dozen colleges and universities are requiring students to get COVID-19 vaccine

At a growing number of colleges and universities around the U.S., getting a COVID-19 vaccination is a must for students who plan to return to campus this fall.

Since Rutgers University in New Jersey first announced in March that students would have to be immunized, at least a dozen schools have said they will require proof of inoculation for those who want to attend classes in person and participate in other on-campus activities.  Rutgers President Jonathan Holloway said the university's vaccine mandate is essential for reaching "herd immunity" on campus and that students are on board. "The reaction has been wholly positive. They know that this is the path to reopening," he told CBS News' Meg Oliver.
