How long does your mumps vaccine last?

The mumps vaccine, typically given as part of the MMR (measles, mumps, rubella) vaccine, provides long-lasting immunity. Studies suggest that the vaccine is effective for at least 20 years, and many individuals may have protection for life after receiving the recommended doses. However, some people may still be at risk for mumps, especially in outbreaks or if they have received fewer than the recommended doses.
