The University of Southern Maine has notified more than 400 students that they are banned from campus until they meet the latest vaccination requirements for mumps. This follows an outbreak of mumps in Maine that affected at least one university student.

The list includes about 20 students who have declined vaccinations on religious or philosophical grounds.

All of those who fail to get shots will be kept out of classes, with the sole exception of students who are medically exempt from the vaccination. Those students must receive a special pass.

There have been eight confirmed cases of the mumps in Maine, and another 35 suspected cases.
