Comprehensive Guide to the MMR Vaccine: Safeguarding Against Measles, Mumps, and Rubella

Vaccine Purpose
Immunization against measles, mumps, and rubella is essential, especially for women who are pregnant, as rubella infection can lead to birth defects. Mumps can cause swelling of the testicles and future fertility issues, while measles can cause severe complications like blindness in children. Timely vaccination is key to preventing these illnesses.

Common and Brand Names
The vaccine’s active component is a live virus combination, marketed as M-M-R II.

Vaccine Formulation
Reconstituted doses of 0.5 ml contain at least 1,000 CCID50 of measles virus, 12,500 CCID50 of mumps, and 1,000 CCID50 of rubella virus.

How It Functions
Upon injection, the vaccine stimulates the immune system to produce antibodies specifically targeting measles, mumps, and rubella, building immunity against these diseases.

Recommended Administration Age
Suitable for anyone aged 12 months and older, the vaccine can be administered at any appropriate time after this age.

Usage Recommendations
The M-M-R vaccine offers protection against all three diseases simultaneously. It is particularly crucial during outbreaks and should be administered to adolescent and adult women of childbearing age who are not pregnant to prevent rubella infection during pregnancy, thereby safeguarding fetal health.

Precautionary Measures

Access to emergency medications such as epinephrine (1:1000) is vital in case of allergic reactions.

Caution is necessary for individuals with a history of seizures, brain injury, or conditions sensitive to fever; post-vaccination fever should be monitored.

People allergic to eggs should be vaccinated carefully, with emergency treatment readiness.

Those with low platelet counts need close monitoring, as reactions could be more severe. Additional doses may be required based on serologic testing.

This vaccine should not be administered during pregnancy.

Lactating women should exercise caution, since live rubella virus may pass through breast milk.

HIV-positive adults without immunosuppression can safely receive the vaccine.

Possible Side Effects

Common: Brief burning or stinging sensation at the injection site.

Occasional: Fever, mild rash, or measles-like symptoms.

Rare: Mild redness, swelling, sore throat, fatigue, and very rarely neurological issues such as seizures or encephalitis.

Other rare reactions include allergic responses, joint pain, or swelling.

The standard dose is a 0.5 ml injection, given subcutaneously or intramuscularly.
