Mumps is bad this year in the U.S. So far, more than 4,600 cases have been reported. So experts voted on Wednesday to recommend that people at high risk of catching mumps during an outbreak get a booster dose of the vaccine, even if they’ve already been vaccinated twice. Vaccine advisers also recommended a brand-new shingles vaccine — one that protects people much better than the older vaccine. They voted to recommend people use the new one, called Shingrix, even if they’ve had the older one. advertisement Members of the Advisory Committee on Immunization Practices (ACIP) had hoped to get some fresh information on whether adding a third dose could help control outbreaks of mumps, which are becoming increasingly common on university campuses, as well as in church groups, community recreation centers and elsewhere.

In a few people it can cause meningitis, deafness or sterility. “The information is limited although the limited information would indicate that the third dose does reduce your risk of getting the disease,” said Dr. William Schaffner of Vanderbilt University and the National Foundation for Infectious Diseases. “It’s a good thing to do. We did it at Vanderbilt. We had a few cases. They targeted one fraternity (with vaccines),” he added. When a few cases turned up outside the fraternity, health officials used an approach called ring vaccination — vaccinating everyone in contact with someone who got sick.

All 27 confirmed cases had been vaccinated against mumps before, usually with the combined measles-mumps-rubella (MMR) vaccine. “There is no reason to leave campus and no reason to be alarmed. The University is taking aggressive action to educate the campus community about
