It is a combined measles, mumps, and rubella live and attenuated vaccine that is indicated for active immunization against infection by measles, mumps and rubella.

Frequency of shots:
Immunization at 12 months of age or as soon as practicable thereafter. A second dose of MMR is recommended at least 1 month after the first dose or at 4-6 years of age.

Who can use this:
- Recommended to all children to get two doses of MMR (measles-mumps-rubella) vaccine, starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age.
- Students at post-high school educational institutions who do not have presumptive evidence of immunity
- Adults who do not have presumptive evidence of immunity should get at least one dose of MMR vaccine.

Who cannot use this:
- Has any severe, life-threatening allergies. A person who has ever had a life-threatening allergic reaction after a dose of MMR vaccine, or has a severe allergy to any part of this vaccine, may be advised not to be vaccinated. Ask your health care provider if you want information about vaccine components.
- Is pregnant or thinks she might be pregnant. Pregnant women should wait to get MMR vaccine until after they are no longer pregnant. Women should avoid getting pregnant for at least 1 month after getting the MMR vaccine.
- Has a weakened immune system due to disease (such as cancer or HIV/AIDS) or medical treatments (such as radiation, immunotherapy, steroids, or chemotherapy).
- Has a parent, brother, or sister with a history of immune system problems.
- Has ever had a condition that makes them bruise or bleed easily.
- Has recently had a blood transfusion or received other blood products. You might be advised to postpone MMR vaccination for 3 months or more.
- Has tuberculosis.
- Has gotten any other vaccines in the past 4 weeks. Live vaccines given too close together might not work as well.
- Patient is not feeling well. A mild illness, such as a cold, is usually not a reason to postpone a vaccination. Someone who is moderately or severely ill should probably wait.
