What should you know about rubella vaccination age?

MMR protects against measles, mumps and rubella. The routine age is set by the local immunisation schedule, so the exact timing can differ between countries and may be adjusted for travel, an outbreak or a child's medical circumstances. A child who started late can often be assessed for catch-up rather than restarting the whole course. A written record, clinic register or vaccination card helps a clinician decide whether another dose is needed.

Rubella infection can cause fever, swollen glands and joint pain, and infection during pregnancy can seriously affect an unborn baby. Vaccination is preventive; it does not treat an illness that is already causing symptoms. The MMR vaccine is a live vaccine, so pregnancy and some immune conditions require specific medical advice before vaccination.

Check the person's vaccination record and ask a GP, paediatrician or vaccination clinic to compare it with the schedule used where you live. If records are unavailable, tell the clinician the person's age, previous countries of residence, known vaccine reactions, immune conditions and whether pregnancy is possible. Do not delay routine advice because the first opportunity was missed; a clinician can explain the appropriate catch-up plan.

Before an appointment, mention a severe reaction to a previous dose, a serious allergy, current illness, medicines that affect immunity or a recent blood product. After vaccination, mild soreness or a short-lived fever can occur. Seek advice if a reaction is severe, unusual or worsening.

Contact a healthcare professional promptly if a recently vaccinated person has breathing difficulty, facial swelling, collapse, a seizure or a rapidly worsening reaction. These symptoms need urgent assessment. If someone may have been exposed to rubella, develops a rash or has fever and swollen glands, call ahead before visiting a clinic, especially if they are pregnant or may have contact with a pregnant person. This helps the service give infection-control advice and arrange the right assessment.

Ask which rubella-containing vaccine is appropriate, whether the available record shows enough protection, and whether a catch-up dose is recommended. Also ask whether pregnancy, immune-suppressing treatment, an allergy or another health condition changes the timing, and what symptoms should prompt a call after vaccination.
