Measles is a very infectious viral illness that is spread by coughs and sneezes. If you are not protected and have even passing contact with someone who has measles, the chances are that you will be infected too. If you catch measles you will probably feel very poorly and be off school or work for around 10 days. There is no treatment or cure for measles.
Symptoms of measles include fever, sore red eyes, and rash. It can be a very serious infection for some people.
Complications are more likely to occur in certain groups including people with weakened immune systems, babies under one year old and pregnant women. Complications can include chest and ear infections, fits, diarrhoea, encephalitis (infection of the brain) and brain damage. Those who develop complications may need to be admitted to hospital for treatment.
Measles is serious, around one in 5,000 individuals with measles is likely to die and since 2006, there have been 3 deaths from measles in England and Wales.
Mumps is a viral illness that is spread by coughs and sneezes or close contact with someone who already has the infection.
Symptoms of mumps usually last around 2 weeks and can include headache and fever but the most common symptom is swelling of the glands at the side of the face. This can give you the appearance of having a ‘hamster face’ and can cause pain and difficulty swallowing.
Complications of mumps can be very painful and can include inflammation of the ovaries or testicles, and in rarer cases, the pancreas. Mumps can also cause viral meningitis and encephalitis (infection of the brain). Although permanent hearing loss after mumps is rare, around one in 20 people infected may have temporary hearing loss.
There is currently no medication to cure mumps so treatment is focused on relieving symptoms. If you develop mumps you will probably need some bed rest and painkillers during this time. You may also need to eat soft foods that do not require a lot of chewing. Most cases of mumps now occur in young adults who haven’t had 2 doses of MMR vaccine.
Rubella is a viral illness, often called German measles, that is now rare in the UK thanks to the success of the MMR vaccine. It is spread in a similar way to mumps and measles. For most people, it is usually a mild condition that gets better in 7 to 10 days without treatment. However, if pregnant women develop rubella it can be very serious for their unborn baby.
Symptoms of rubella include a rash, cold-like symptoms, and aching joints.
Complications of rubella are rare but if a pregnant woman catches rubella during pregnancy, there can be devastating consequences for her unborn baby which could lead to the baby being born with cataracts (eye problems), deafness, heart problems or brain damage
The MMR vaccine
The MMR vaccine is a single injection that is administered into the thigh of young children or the upper arm of older children or adults. It is a live vaccine which means that it contains weakened versions of measles, mumps and rubella viruses. These have been weakened enough to produce immunity without causing disease.
The MMR vaccine gives long lasting protection with just 2 doses of the vaccine. The first dose is given at the age of 12 months and the second dose is given at around 3 years and 4 months, before starting school. Having both doses gives long lasting protection against measles, mumps and rubella. In adults and older children the 2 doses can be given with a one month gap between them.
The MMR vaccine protects against 3 infections; measles, mumps and rubella. These are viral infections that can quickly spread to unprotected children and adults – they spread more easily than flu or the common cold.
The MMR vaccine is the safest and most effective way to protect yourself against measles, mumps and rubella. Since the vaccine was introduced in 1988, these conditions have become rare in the UK. However, outbreaks of disease, especially measles, have occurred when the number of people having the vaccine has dropped. If you are unsure whether you have previously had the vaccine or not, you can check with your GP, having further doses will not cause any harm.
Why should you or your children have the vaccine?
You should have the vaccine to protect yourself against 3 serious infections. By doing so you will also help to protect others who can’t have the vaccine. These include unborn babies, infants who are too young to have the vaccine and children or adults who can’t have the vaccine because they have weakened immune systems. This will help to prevent large outbreaks of disease.
You should also have the vaccine if you work with young children or care for people as part of your work.
Passing on measles to children who are too young to have MMR vaccine or to someone who is already ill, can have very serious consequences for their health. As a precaution, women should avoid getting pregnant for one month after MMR vaccination.
Those who should not have the MMR vaccine
As the MMR vaccine is a live vaccine it should not be given to pregnant women or people who are severely immunosuppressed, for example those who have had a bone marrow transplant or are taking immunosuppressant medicines.
If you are unsure discuss this with your doctor. If you have had a confirmed anaphylactic reaction to neomycin you should not have the vaccine. If you have had a confirmed anaphylactic reaction to gelatine you should speak to your GP and arrange to have the gelatine-free vaccine.
How the MMR vaccine works
The MMR vaccine is a live vaccine that protects against measles, mumps and rubella. Two doses are given by injection into the leg or upper arm.
Your immune system responds to the vaccine by producing cells which recognize and remember each of the 3 viruses. If you are in contact with any of the diseases in the future, these cells will wake up and activate your body to rapidly produce antibodies. This protection is usually long lasting.
How safe is the vaccine?
The combined MMR vaccine has been safely protecting children for many years in many countries worldwide. In the UK, millions of doses have been given since it was introduced in 1988. Before vaccines can be used, they have to be thoroughly tested for safety. Although there may be some side effects from vaccination, they are usually mild and much less severe than the disease itself. Serious reactions following vaccination are rare.
Many studies have taken place to look at the safety and effectiveness of MMR vaccine. The evidence is clear that there is no link between MMR vaccine and autism.
Does the vaccine work?
Yes, the vaccine is very good at providing protection against measles, mumps and rubella. Over 99% of those who have 2 doses of the vaccine will be protected against measles and rubella. Although mumps protection is slightly lower, cases in vaccinated people are much less severe.
MMR was introduced in the UK in 1988, and it is now rare for children to develop these infections. There have been outbreaks of measles and mumps in recent years. These tend to occur where levels of vaccination are low, but they can happen at any time so it’s important to make sure that you are protected by having 2 doses of MMR vaccine.
Not everyone gets side effects from the vaccine. To provide protection, the vaccine mimics the 3 infections that it protects against. Some people may get a rash that looks like a mild form of measles, the face may swell to look like mumps or they may have pains in the joints like rubella. These side effects occur in a small percentage of people after the first dose.
The side effects from the measles part of the vaccine are usually seen when the vaccine starts to work – around 6 to 10 days after vaccination. Swelling of the face or joint pains tend to come on around 2 to 3 weeks after vaccination when the mumps and rubella vaccines start to work.
Side effects such as a rash or neck swelling only last for around 2 to 3 days and are not infectious. This means that if you do develop these side effects, you cannot pass on the infection to others. On rare occasions, a reddish-purple rash that looks like tiny bruises can occur up to 6 weeks following vaccination.
Does the MMR vaccine contain gelatine?
In the UK, we have 2 MMR vaccines which work very well. One of them contains gelatine derived from pigs and the other one doesn’t. If you would prefer to have the vaccine that does not contain gelatine, talk to your practice nurse or GP.
If you think you have measles, mumps or rubella
If you think you might already have measles, mumps or rubella, it’s important to reduce the risk of spreading the infection to other people. You should:
- phone your GP for advice, they may need to make arrangements for you to visit the surgery at the end of the day so that you avoid contact with people who are more vulnerable to the infection, such as young children and pregnant women
- avoid work or school for at least 4 days from when you first developed the measles rash
- make arrangements to have any outstanding doses of the vaccine once you have recovered. This will protect you against the other 2 infections
All those who are allergic to eggs, including children with asthma, can have the MMR vaccine at their GP Surgery. Anyone who has had a documented anaphylactic reaction to MMR vaccine itself should be assessed by an allergist.

Who needs to have the vaccine
All children over the age of one year should have 2 doses of the vaccine, the first dose is usually given at one year of age and the second dose is usually given at age 3 years and 4 months old.
Older children and adults should have 2 doses of the vaccine with a one month gap between them.
Pregnant women should make sure that they are protected before they become pregnant or make sure they are vaccinated soon after the baby is born.
It is never too late to have the vaccine if you haven’t had 2 doses.
Where you can get the vaccine
From your GP surgery
All children aged one year to 3 years 4 months should be offered the vaccine as part of their routine vaccinations at their GP surgery.
Older children and adults should contact their GP practice if they have had one or no doses of the vaccine.
Pregnant women can have the vaccine at their GP surgery after their baby is born if they don’t have 2 documented doses.
At your school
Some adolescents and young adults are offered their missing doses of MMR vaccine with their other teenage booster vaccines.
