An injected vaccine, MMR (officially known as M-M-R® II) is an immunization that helps prevent infection with measles, mumps, and rubella. It is approved for use in people who are over 12 months old. The vaccine is typically given as two separate doses. As with other live vaccines, it is injected just under the skin -- preferably on the upper arm.
Most people tolerate this product well; if side effects do occur, they are often mild and easy to treat. The most commonly reported side effects of the MMR immunization include fever, temporary joint stiffness, and mild rash. To ensure your safety, talk to your healthcare provider about any potential risks, including drug interactions and side effects, before getting the vaccine. Also, tell your healthcare provider if you are pregnant, thinking of becoming pregnant, or breastfeeding.
