MMR stands for Mumps Measles and Rubella. These are highly infectious diseases that can easily spread between unvaccinated people and can lead to serious problems including meningitis. The MMR vaccine is usually given to children before they reach school age but catch-up doses are offered in school to those that missed out.
How is it given
The vaccine is given as a single injection into the upper arm or thigh.
Who should have it
All children who haven’t yet been vaccinated. The MMR catch-up vaccine is typically given to (boys and girls) aged 12 to 16 (year 8 to year 11). There is no age limit for MMR vaccinations, once a child has left school please speak to your GP.
Why it matters
Measles, mumps and rubella are highly infectious diseases that can lead to serious health complications, including meningitis, hearing loss, and problems during pregnancy. By getting vaccinated you’re helping protect yourself and others — especially those who can’t be vaccinated — and helping to stop outbreaks in schools and communities.
Side effects
Side effects are usually mild and short‑lived.
They can include:
- slight fever, mild rash or swelling a few days after vaccination
- slight soreness at the injection site

Additional information
If we have no record of MMR then you need to receive a second booster vaccination at least one month after the first which can be arranged by vaccination team.
The MMRV vaccine is a combined childhood immunisation protecting against four diseases: Measles, Mumps, Rubella, and Varicella (chickenpox), replacing the older MMR in the UK from January 2026. It is typically given in two doses at 12 and 18 months of age, preventing serious complications like pneumonia or brain inflammation. Your GP will advise which version your child will receive (MMR or MMRV) based on your child’s date of birth.
