Measles, Mumps & Rubella (MMR) Vaccine

What are measles, mumps and rubella?

Measles, mumps and rubella are highly contagious viral diseases that have the potential to be very serious. They can be spread from infected people through the air.

The measles virus causes fever, cough, runny nose, pink eye and rash. If the measles virus infects the lungs, it can cause pneumonia. Some older children infected with the virus will suffer from brain inflammation, which can cause seizures and permanent brain damage.

The mumps virus usually causes fever, headache and swollen glands. It can lead to deafness, meningitis, painful swelling of the testicles or ovaries and, in some cases, death.

Rubella, also known as German measles, causes rash, low-grade fever and arthritis. If a pregnant woman gets rubella, she could miscarry or give birth to a baby with serious birth defects.

What is the MMR vaccine?

The measles, mumps and rubella (MMR) vaccine is a recommended childhood vaccine. This three-in-one vaccine protects against measles, mumps and rubella and is required for children to enter school in most states. Children need two doses of the vaccine, while adults who need it should get at least one dose.

Who should get the MMR vaccine?

Children should get the first dose of MMR vaccine at 12-15 months of age, and the second dose at 4-6 years of age. Children can get the second dose at any age, as long as it is at least 28 days after the first dose.

Adults who have not been vaccinated nor had the diseases, or don't know if they've been vaccinated or had the diseases, and who meet any of the following criteria:

  • Adults born after 1956
  • Work in a medical facility

Who should not get the MMR vaccine?

  • Anyone who has ever had a life-threatening allergic reaction to gelatin, the antibiotic neomycin, or to a previous dose of MMR vaccine
  • Anyone who is moderately or severely ill

Anyone with the following characteristics should check with their healthcare provider about whether they should get the MMR vaccine:

  • Has HIV/AIDS, or another disease that affects the immune system
  • Is being treated with drugs that affect the immune system, such as steroids, for two weeks or longer
  • Has any kind of cancer
  • Is taking cancer treatment with X-rays or drugs
  • Has ever had a low platelet count (a blood disorder)

Is the MMR vaccine safe for pregnant women?

Pregnant women should wait to get their MMR vaccine until after they have given birth. Women should avoid getting pregnant for four weeks after getting the MMR vaccine.

What are the side effects of the MMR vaccine?

Mild-to-moderate problems:

  • Fever, rash and seizures
  • Swollen glands in the cheeks or neck
  • Temporary pain and stiffness in the joints
  • Temporary low blood platelet count

Severe problems (rare):

  • Deafness
  • Permanent brain damage
  • Serious allergic reactions, with symptoms including:
    • Difficulty breathing
    • Wheezing
    • Hives
    • Pale skin
    • Fast heartbeat
    • Dizziness

Over-the-counter pain relievers such as acetaminophen or ibuprofen can help ease pain and reduce fever.

It's extremely rare for these vaccines to cause serious harm or death. If the person getting the vaccine has a serious reaction, seek immediate medical attention.
