The MMR vaccine is given as a single injection into the muscle of the thigh or upper arm.
There may be some redness and swelling on the skin where the injection is given, but this should soon disappear.
MMR dosing schedule
The first dose of MMR is given to babies aged around 13 months, and the second dose between the ages of 3 and 5 years.
In adults, the second MMR dose must be given at least 1 month after the first.

Single vaccines for measles, mumps and rubella
Single vaccines for the 3 separate conditions (measles, mumps and rubella) are not available on the NHS, but are available at some private clinics.
But there are certain drawbacks to single vaccines against measles, mumps and rubella.
Having each of the single vaccines separately usually involves scheduling them several weeks or months apart.
The government recommends that children should have the MMR vaccine within a set timescale.
Using single vaccinations increases the risk of fewer children receiving all the necessary injections.
There are currently no licensed single vaccines for measles or mumps in the UK, which means the single vaccines available haven't been quality checked to make sure they're safe and effective.
