Mumps is back, and is having its worst year in a decade, fueled in part by its spread on college campuses. Since classes began at the University of Missouri in August, school officials have identified 193 mumps cases on campus, with more unreported cases likely. And nationwide, more than 4,000 cases have been reported to the Centers for Disease Control and Prevention — nearly triple the cases in 2015 and the largest spike in 10 years. The spike has some public health officials asking questions about the existing vaccine protocol.
