Measles, Mumps, and Rubella (MMR) Vaccination: What Everyone Should KnowCDC recommends that people get MMR vaccine to protect against measles, mumps, and rubella. Children should get two doses of MMR vaccine, starting with the first dose at 12 to 15 months of age, and the second dose at 4 through 6 years of age. Teens and adults should also be up to date on their MMR vaccination. Two MMR vaccines are available for use in the United States, M-M-R II and PRIORIX. M-M-R II and PRIORIX are fully interchangeable for all indications for which MMR vaccination is recommended. Children may also get MMRV vaccine, which protects against measles, mumps, rubella, and varicella (chickenpox). This vaccine is only licensed for use in children who are 12 months through 12 years of age.

- students at post-high school education institutions
- healthcare personnel
- international travelers
International travelers
People 6 months of age and older who will be traveling internationally should be protected against measles. Before any international travel—

It is safe for breastfeeding women to receive MMR vaccination. Breastfeeding does not interfere with the response to MMR vaccine, and the baby will not be affected by the vaccine through breast milk.
Groups at increased risk for mumps because of a mumps outbreakDuring a mumps outbreak, public health authorities might recommend an additional dose of MMR vaccine for people who belong to groups at increased risk for getting mumps. These groups are usually those who are likely to have close contact, such as sharing sport equipment or drinks, kissing, or living in close quarters, with a person who has mumps. Your local public health authorities or institution will communicate to the groups at increased risk that they should receive this dose. If you already have two doses of MMR, it is not necessary to seek out vaccination unless you are part of this group.
