|Generic Name||Brand Name|
|measles, mumps, and rubella (MMR) vaccine||M-M-R II, Priorix|
|measles, mumps, rubella, and varicella (MMRV) vaccine||Priorix-Tetra, ProQuad|
How It Works
The vaccine helps your body make chemicals called antibodies to fight off the viruses. The vaccine is given as a shot (injection).
There is a measles, mumps, rubella, and varicella (MMRV) shot that also protects against chickenpox (varicella). Talk to your child's doctor or public health nurse about the pros and cons of the MMRV shot. It can be given to children age 12 and younger.
Why It Is Used
Two doses are given. In BC, the first shot is given at 12 months of age, and the second dose is usually given around 4 to 6 years of age as MMRV.
Sometimes MMR shots are given as early as 6 months of age, such as during a measles outbreak or if the child is travelling to an area where measles is common.
Adults born before 1970 generally are considered immune to measles and mumps. However, some of these individuals may be susceptible and should talk to their health care provider about getting vaccinated.
In BC, adults born after 1970 who did not have measles or the vaccine should get two doses.
How Well It Works
One dose given at 12 or 15 months of age is about 85% to 95% effective. After the second dose is given, it is nearly 100% effective.
- Soreness, redness, and swelling where the shot was given.
- Temporary pain or stiffness in the joints (usually affects women).
Mild reactions that may occur one to two weeks after getting the vaccine include:
- Mild rash.
- Swollen glands in the cheeks or neck (this is a rare).
Even though serious allergic reactions are rare with this vaccine, call 911 or your local emergency number right away if you or your child has trouble breathing. Call your doctor or public health unit if you or your child has a high fever or anything unusual after having the shot.
A child who has had a severe allergic reaction to a previous dose should not get another dose of the vaccine. Tell your doctor or public health nurse if your child has had a severe reaction to any vaccine or has severe allergies.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
People with a mild illness, such as a cold, can get the vaccine. But if they are more ill, they should wait until they are better. If women get an MMR or MMRV vaccine, they should wait 4 weeks until getting pregnant.
- Pregnant women
- People who have had a history of anaphylactic reaction to a previous dose of a measles, mumps, or rubella containing vaccine or to any component of the product, with the exception of an egg allergy
- Have active, untreated tuberculosis (TB)
Talk with your doctor before getting the vaccine if you:
- Are immunocompromised as a result of disease or therapy.
- Have a family history of congenital immunodeficiency.
- Have ever had a low platelet count.
- Have recently had a transfusion or received any blood products.
In the past, children with allergies to eggs were thought to be at high risk for serious reactions to the MMR vaccine because it is made with chick embryo cells. But recent studies have shown that the risk of allergic reaction from the MMR vaccine is extremely low for these people, and vaccination is recommended.
