    Once you've had mumps, your body builds immunity and you usually won't get it again. However, the MMR vaccine is the best way to prevent mumps in the first place.

  • Why do my salivary glands swell when I have mumps?
    MedlinePlusMay 2026

    The mumps virus attacks your salivary glands, which are the glands that make saliva in your mouth. When the virus infects these glands, they become swollen and tender, usually under your ears or jaw.

    Serious complications from mumps are rare. Most people recover completely within 7 to 10 days without any lasting problems.
