Yep. I got mumps. My husband and his brothers got mumps and we were all immunized. Here's the study showing the biggest outbreak of mumps in recent American history and most of the people were immunized:
In a study reported in last week's New England Journal of Medicine, researchers from the Centers for Disease Control and Prevention and several Midwestern state health departments examined the 6,584 cases in the Midwestern outbreak. They found that the incidence was four times higher among people 18 to 24 years old than in all other age groups combined. This was despite the fact that 84% of the mumps patients in that age group (and 63% of the patients overall) had received the recommended two doses of mumps vaccine.Immunization does not confer 100% immunity. And the problem with this outbreak is that mumps is relatively harmless in children. Uncomfortable, yes. Miserable, yes. Deadly? No. But in young adults, it can cause sterilization and reproductive problems.
