measles, mumps, and rubella vaccine
How does this medication work? What will it do for me?
The measles, mumps, and rubella vaccine belongs to a group of medication known as vaccines. It is used to prevent infection with measles (rubeola), mumps, and rubella (German measles).
The measles, mumps, and rubella vaccine is made from live measles, mumps, and rubella viruses that have been weakened to the point where they will not cause disease. This vaccine is intended for people 12 months of age or older. In some cases, the doctor may decide to use this medication in people younger than 12 months of age. It works by stimulating the production of a person’s own antibodies, which remain in the body ready to attack any of the three types of virus should they enter the body naturally.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you or your child is receiving this vaccine, speak to your doctor.

How should I use this medication?
For anyone 12 months or older, the recommended dose is 0.5 mL injected subcutaneously (under the skin), preferably into the outer part of the upper arm. For children, a second dose (0.5 mL) is usually recommended to be given at least one month after the first dose (this is usually given either at the age of 18 months or at the age of 4 to 6 years, before they start school) to better protect against the measles. If a child was vaccinated before they were 12 months old, 2 additional doses (0.5 mL per dose) should be given after they are 12 months old.
Children and adolescents 17 years or younger who were not immunized in early infancy should receive 2 doses of the vaccine (0.5 mL per dose). The first dose should be given as soon as possible and the second dose should be given 2 months later.
Adults who are susceptible to these diseases but were not immunized during their childhood should receive one dose (0.5 mL).
This vaccine is given by a health care professional in a doctor’s office or clinic.
It is very important that this vaccine be given on a regular schedule as prescribed by the doctor. If you or your child miss a dose of this vaccine, check with your health care professional. Add all vaccines to your or your child’s immunization record.
Store this medication in the refrigerator and protect it from light. The diluent used to reconstitute the vaccine can be stored at room temperature or in the fridge but should not be frozen.

Are there any other precautions or warnings for this medication?
Before you or your child receives this vaccine, be sure to inform your doctor of any medical conditions or allergies you or your child may have, any medications you or your child is taking, whether you are pregnant or breast-feeding, and any other significant facts about your child or your health. These factors may affect the vaccine you or your child is receiving.
Allergy to eggs: People who have an allergy to eggs that causes anaphylaxis (hives, swelling of the mouth and throat, difficulty breathing) should discuss with their doctor the risks and benefits of receiving this vaccine and whether any special monitoring is needed.
HIV infection that is not symptomatic: Children and young adults known to be infected with HIV but without symptoms may be vaccinated; however, they should be monitored closely for exposure to vaccine-preventable diseases because vaccination may be less effective.
Immune system: As with any vaccine, this vaccine may not be as effective for people with a weakened immune system (such as people who are on chemotherapy, have had an organ transplant, or have HIV).
Infection: Your child’s doctor may decide to delay this vaccine if your child has an acute infection or fever. Mild infections without fever, such as colds, usually do not require delay of the vaccine.
Low platelet counts: People with low platelet counts (thrombocytopenia) or who experienced low platelet counts with the first dose of this vaccine should discuss with their doctor how this medication may affect their medical condition and whether any special monitoring is needed.
Seizures or fever: People with a personal or family history of seizures, a history of brain injury, or a condition in which fever should be avoided should discuss with their doctor how this medication may affect their medical condition and whether any special monitoring is needed.
Vaccine protection: As for any vaccine, the measles, mumps, and rubella vaccine may not protect 100% of people who receive it and may not prevent infection in those people already infected with the viruses.
Pregnancy: This vaccine is not recommended for women who are pregnant or who intend to become pregnant within the next 3 months. Women who may become pregnant should take necessary precautions to avoid pregnancy for 3 months following vaccination. If you become pregnant within 3 months of receiving the vaccine, talk to your doctor.
Breast-feeding: The rubella virus may pass into breast milk but it is not known if the measles or mumps vaccine passes into breast milk. If you are a breast-feeding mother and are receiving this vaccine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of this vaccine have not been established for children younger than 12 months of age. In special situations, however, your child’s doctor may recommend this vaccine for children under 12 months of age.
