“The most effective way to reduce the risk of getting mumps and its complications is to be up to date with MMR vaccinations,” said Dr. Jeff Duchin, Health Officer for Public Health – Seattle & King County. “Because some people do not respond to the vaccine and mumps spreads easily from person to person, outbreaks can still occur in vaccinated populations. But, if unvaccinated, many, many, more people would become ill .”
