Mumps and rubella vaccine: what should you know?

MMR vaccination helps the immune system recognise measles, mumps and rubella. It does not treat an infection that is already developing. After vaccination, a person may have a sore injection site, feel tired or develop a mild fever. Some people notice swollen glands or joint aches for a short time. These effects are different from severe allergic symptoms, which need urgent attention.

Rubella is also called German measles. Infection during pregnancy can be particularly concerning, so tell a clinician if you are pregnant, may be pregnant or have recently been exposed. The timing of doses and any catch-up plan depends on your record and circumstances.

Keep your vaccination record and observe how you feel over the following days. Drink fluids and rest if mildly unwell. Ask a pharmacist or clinician which medicine is suitable for fever or joint pain, especially for a child or someone with other health conditions. Contact the vaccination service if you are unsure whether another dose is due, or if you have missed an appointment.

Seek urgent help for facial swelling with breathing difficulty, wheezing, faintness, widespread hives or trouble swallowing soon after vaccination. Arrange medical advice for a persistent high fever, marked swollen glands, severe headache, unusual drowsiness or symptoms after contact with confirmed mumps or rubella. Pregnancy concerns should be discussed promptly with a maternity or GP team.

Ask which MMR doses are recorded, whether a further dose is advised, what reactions are expected for your age, and what to do if pregnancy or an immune problem affects your vaccination plan.
