When should you immunise?
In the UK, childhood immunisations start when a baby is 2 months old.
The first MMR vaccination should be given at 13 months when the immunity acquired from the mother starts to wear off because if the vaccine is given when the baby still has antibodies to the disease it protects against, the antibodies may stop the vaccine working.
It is important to stick to the schedule as delaying immunisation can leave a baby unprotected.
You can find out exactly when each vaccination is given on our Immunisation schedule.
