Measles, Mumps and Rubella (MMR) Vaccine FAQs

The MMR vaccine is one needle that helps to protect against three serious and contagious infections: measles, mumps and rubella, also known as German measles.

What are measles, mumps and rubella?

Measles

Measles is caused by a virus and is the most contagious vaccine preventable disease. It spreads easily through coughing, sneezing and even talking. Symptoms usually start with fever, runny nose, cough and red eyes, followed by a red rash that appears around the face and spreads to the chest, arms and legs. Measles can cause ear infections, pneumonia and swelling of the brain called encephalitis, which can lead to seizures, deafness, mental disabilities and even death.

Mumps

Mumps is a viral infection of the salivary glands that spreads through coughing, sneezing and close face-to-face contact. It can cause fever, headache and swelling of the salivary glands underneath the jaw bone. Mumps can lead to deafness and meningitis, which is an inflammation of the fluid and lining covering the brain and spinal cord. Mumps can also cause painful, swollen testicles in teenage boys or men and a painful infection of the ovaries in women.

Rubella / German measles

Rubella / German measles is caused by a virus that spreads through coughing, sneezing and close face-to-face contact. It usually starts with a low fever and mild cold symptoms, followed by a rash, and swelling of the glands in the neck. Rubella is usually a mild illness in children but can be more severe in teenagers and adults, who may suffer from aches, pains and swelling in the joints. It can be followed by chronic arthritis and can also cause temporary blood clotting problems and swelling of the brain, called encephalitis. If a woman gets rubella during the first 20 weeks of her pregnancy, her baby may be born with birth defects that can include heart disease, cataracts, deafness and mental disabilities.

Who should get the publicly funded (free) MMR vaccine?

  • Children should receive the first dose of MMR vaccine on, or just after, their first birthday
    • the second dose should be given at 4-6 years of age, and it is called the MMRV vaccine since it is combined with varicella, also known as chicken pox.
  • Infants 6 to 11 months of age should receive an MMR if travelling to a place where diseases are a concern, but 2 regularly scheduled doses will still be needed after the age of one.
  • Anyone born in 1970 and later,who does not know if they have had measles, mumps or rubella, or if they have been immunized for them, can safely get the MMR vaccine.

What if I am pregnant or breastfeeding?

  • Women of childbearing age, who are not pregnant, should be vaccinated if they do not have a least one documented dose of rubella vaccine or evidence of immunity.
