  • The measles, mumps and rubella (MMR) vaccine protects against 3 viral infections – measles, mumps and rubella.

Get vaccinated against measles

Measles is currently circulating in Aotearoa New Zealand. You can find details of the latest exposures(external link) on this Te Whatu Ora page. 

  • Measles spreads very quickly and can cause serious complications.
  • Please be aware of measles symptoms, including fever, cough and rash.
  • If you are not immune and have been exposed to measles, MMR vaccination within 72 hours of exposure may provide protection and help limit the spread. 
  • Get vaccinated to protect yourself and your loved ones from catching and spreading measles. If you're not sure if you need a measles vaccine, find out by answering the questions on this immunisation page(external link).  

MMR vaccine

MMR is a vaccine that protects you against 3 viral infections – measles, mumps and rubella. There are no single vaccines available for these infections.

The MMR vaccine protects you against 3 viral infections – measles, mumps and rubella. The vaccine is a live vaccine, which is made using live mumps, measles and rubella viruses that have been weakened (or attenuated).

After vaccination, the weakened vaccine then teaches your immune system to recognise the virus, so it knows how to attack if it ever comes across it. Read more about live vaccines.

Vaccination with the MMR vaccine is the best way to protect against measles, mumps and rubella. While these infections may be mild in some people, they can cause serious complications in others.

  • Measles: The infection can be serious, with 1 in 10 needing to go to hospital. Complications include diarrhoea/hamuti (which can lead to dehydration), ear infections (which can cause hearing loss), pneumonia (which is the most common cause of death) and encephalitis (brain inflammation), which can cause brain damage. Read more about measles.
  • Mumps: The symptoms of mumps are usually mild, such as swollen salivary glands (at the side of your face), headache and fever, but it can cause serious complications such as deafness, swollen testicles or ovaries, and meningitis. Read more about mumps.
  • Rubella (also called German measles): This is usually a mild infection that gets better within about 7–10 days, but it becomes a serious concern if a pregnant woman catches the infection during the first 20 weeks of pregnancy. This is because the rubella virus can affect the development of the baby and cause severe health problems such as eye problems, deafness, heart abnormalities and brain damage. Read more about rubella.

(KidsHealth, NZ, 2023)

The MMR vaccine is given as an intramuscular injection (injected into a muscle in your thigh or upper arm). It is given as 2 doses at least 4 weeks apart.

After a single dose of MMR vaccine, 90–95 out of 100 people will be protected from measles, 69–81 protected from mumps and 90–97 from rubella. After a second dose of MMR vaccine the number of people protected from these diseases increases, and almost everyone will be protected from measles and rubella, and up to 88% (88 out of 100 people) protected from mumps.

It's really important to have both doses of the vaccine so you are well protected.

  • Anyone born on/after 1 January 1969 who has not had two doses of the MMR vaccine should have the MMR vaccine.
  • Adults born before 1969 are considered to be immune to measles as measles was very infectious before 1969, and there was no vaccine available in Aotearoa New Zealand until then, so most adults were highly likely to be exposed. The MMR vaccine may still be needed for protection from mumps and rubella – check with your doctor if you are not sure.
  • The MMR vaccine is part of the childhood immunisation schedule(external link) for children at 12 months and 15 months of age.

Women planning a pregnancy

All women of childbearing age need to know if they are protected from rubella. In pregnant women, rubella can cause serious complications to the unborn baby, especially during the first 20 weeks of pregnancy. Immunity from the mother can stop the baby becoming infected.

If you are planning a pregnancy, check with your midwife or doctor whether you need to be vaccinated against rubella. When you get vaccinated, avoid getting pregnant for at least 1 month afterwards. 

Measles outbreak

A single dose of MMR vaccine given to an unvaccinated person within 72 hours of first contact with an infectious person may reduce the risk of developing disease.

For babies, an additional dose of measles vaccine can be given from 6 months of age. Babies immunised before they are 12 months old will still need 2 doses according to the schedule (at 12 months and 15 months).


While measles cases in Aotearoa New Zealand are usually rare, the disease is regularly brought into the country through international travel and there was an outbreak in 2019. If you are travelling overseas, make sure you are fully vaccinated against measles before you go.

If you’re unsure of your vaccination status you can check your Well Child Tamariki Ora or Plunket book, or contact your general practice. If you are not sure whether you have had 2 doses of MMR, it is recommended that you get a vaccine. There are no safety concerns with having extra doses.

If you or your child has had measles, 2 doses of MMR are recommended for mumps and rubella protection. There are no safety concerns with having the vaccine for people who are already protected from measles.

The MMR vaccine is a live vaccine, it should not be given if you:

  • are pregnant
  • have a severe weakness of your immune system
  • have had a severe allergic response (anaphylaxis) to this vaccine or part of this vaccine before
  • have had another live vaccine within the past 4 weeks.

Like all medicines, vaccines can cause side effects, although not everyone gets them. Most side effects are mild and short lived. The chance of a severe reaction from MMR is very small, but the risks from not being vaccinated are very serious.

Because the MMR vaccine combines 3 separate vaccines (measles, mumps, rubella) in a single injection, each vaccine can cause reactions at different times after the injection. There's less chance of side effects after the second dose of MMR than the first.

Side effects What should I do?
  • Mild rash
  • Usually happens 2 to 4 weeks after vaccination.
  • Contact your doctor if you are worried.
  • Swollen glands in the cheeks, neck or under the jaw
  • It can happen 10 to 14 days after the vaccine was given.
  • It can last up to 2 days.
  • Contact your doctor if you are worried.
  • Pain, swelling or redness around the injection site (hard and sore to touch)
  • Heavy arm
  • This is quite common after having the vaccination.
  • It usually starts a few hours after getting the injection and settles within a few days.

  • Fever
  • Generally feeling a bit unwell
  • Headache
  • Feeling faint
  • Nausea (feeling sick)
  • These are quite common for the first 1 or 2 days after receiving the injection.
  • It usually settles within a few days.
  • Tell your doctor if these side effects bother you.

Risk of autism

Vaccines do not cause autism. The confusion came about because in 1998 a British doctor thought there was a link between the MMR vaccine and autism. It has since been found that the doctor had changed the patient data and the laboratory reports were incorrect. The study was removed from the scientific literature and the British authorities removed the doctor’s licence to practice medicine.

There are now many well-conducted studies that have addressed this issue, and some studies have more than one million children in them. These studies strongly show no evidence of any connection between autism and the MMR vaccine, even among at-risk individuals. The MMR vaccine is very safe.

Family medical clinics: You can go to your family medical clinic for vaccinations. They have your medical records and can check to see if you’ve already had a particular vaccination. Either your doctor or a nurse can give the vaccination.

Pharmacies: Many pharmacies can give the MMR vaccine. Usually no appointment is necessary and some pharmacies have longer opening hours than family medical clinics. A pharmacist can check your vaccination record and give the vaccination.

Vaccines on the National Immunisation Schedule(external link) are free. Other vaccines are funded only for people at particular risk of disease. You can choose to pay for vaccines that you are not eligible to receive for free.
