More than 100 colleges across the United States have said they will require students to receive coronavirus vaccines in order to attend in-person classes in the fall, according to a New York Times survey.
Those requirements come as coronavirus cases have continued to climb steadily this spring at U.S. colleges and universities. More than 660,000 cases have been linked to the institutions since the start of the pandemic, with one-third of those since Jan. 1.
Major outbreaks continue on some campuses, even as students have become eligible for vaccines. Salve Regina University in Rhode Island canceled all in-person events for at least a week after more than 30 students tested positive in seven days. Wayne State University in Detroit, a city that has been one of the worst U.S. coronavirus hot spots, suspended in-person classes and on-campus activities in early April.

Schools including DePaul University, Emory University and Wesleyan University are requiring all students to be vaccinated. Others have said they are requiring athletes or those who live on campus to get a shot. Most are allowing medical, religious and other exemptions.
Although private colleges make up the bulk of the schools with vaccine mandates, some public universities have also moved to require the shots.
Students and employees of the University System of Maryland will be required to get vaccinated before returning to campus in the fall, said the chancellor, Jay A. Perman. He said he was particularly concerned about the B.1.1.7 variant, which he described in his announcement last week as more contagious.
“That’s what we’re preparing for,” he said, “more infectious, more harmful variants that we think could be circulating on our campuses come fall.”
At least two dozen colleges have said that they will not require shots while the vaccines have only emergency authorization. California’s public university systems announced that they would require shots after the U.S. Food and Drug Administration grants full approval for the vaccines.
