Children get two doses of MMR vaccine. The first dose is given at months in the UK schedule. The vaccine is not usually given earlier than this because studies have shown it does not work so well in children under 1 year of age. See the short video under 'Is the vaccine safe? A booster dose is given at 3 years and 4 months at the same time as the Pre-school booster.
The MMR vaccine should not be given to people who are clinically immunosuppressed either due to drug treatment or underlying illness. This is because the weakened viruses in the vaccine could replicate too much and cause serious infection. This includes babies whose mothers have had immunosuppressive treatment while they were pregnant or breastfeeding.
There is a catch-up programme for children, teenagers and young adults who have missed out on the MMR vaccine. Anyone of any age who is not sure whether they have had two doses of measles, mumps and rubella vaccines can ask their GP for the MMR vaccine. Because of measles outbreaks in Europe and elsewhere, all travellers are advised to check that they are up to date with MMR vaccination before they travel.
If you are travelling with a baby, the MMR vaccine can be given from six months of age before travelling to a country where measles is a risk or where an outbreak is taking place. See the Travel Health Pro website for more information. Single mumps and rubella vaccines are no longer manufactured anywhere in the world.
The MMR vaccine is not recommended for pregnant women as a matter of caution. However, there are no known risks associated with receiving the MMR vaccine during pregnancy or just before pregnancy. See this Public Health England statement for more information. After two doses of MMR vaccine, about 99 of people out of will be protected against measles, about 88 out of will be protected against mumps, and almost everyone will be protected against rubella.
There are now a large number of studies that show no evidence at all of any link between the MMR vaccine and autism.
In the short film below, experts say why they believe there is no link. See 'Is the vaccine safe? The two vaccines contain different ingredients.
Other brands of MMR vaccines used in other countries may contain different ingredients. If you are not in the UK, ask for the Patient Information leaflet for the vaccine you are offered. Apart from the active ingredients the antigens , MMR vaccines may contain very small amounts of these ingredients:.
The MMR vaccine contains three separate vaccines and their side effects can take place over different time periods. There tend to be fewer side effects after the second dose of MMR. You should consult your doctor if your child experiences fits or a rash that looks like ITP after vaccination. This is mainly to check that it is the vaccine causing the symptoms, and not some unrelated disease.
Symptoms such as fits can be very worrying for parents, but there is no evidence of long-term effects. Children can normally safely receive vaccines in the future. For more information on febrile seizures generally, see NHS Choices. As with any vaccine, medicine or food, there is a very small chance of a severe allergic reaction anaphylaxis. It is always extremely serious but can be treated with adrenaline.
