  • Vaccine Recommendations

What are the current ACIP recommendations for use of immune globulin (IG) for measles, mumps, and rubella post-exposure prophylaxis?

In the 2013 revision of its MMR vaccine recommendations ACIP expanded the use of post-exposure IG prophylaxis for measles. Intramuscular IG (IGIM) should be administered to all infants younger than 12 months who have been exposed to measles. The dose of IGIM is 0.5 mL/kg of body weight; the maximum dose is 15 mL. Alternatively, MMR vaccine can be given instead of IGIM to infants age 6 through 11 months, if it can be given within 72 hours of exposure.

In addition to infants under the age of 12 months, immune globulin may be used as measles post-exposure prophylaxis for susceptible pregnant people or susceptible people who are severely immunocompromised. For details on the dosage and use of immune globulin, please refer to the measles control section in Chapter 7 of the CDC Manual for the Surveillance of Vaccine-Preventable Diseases:

IG is not indicated for people who have received 1 dose of measles-containing vaccine at age 12 months or older unless they are severely immunocompromised. IG should not be used to control measles outbreaks. IG has not been shown to prevent mumps or rubella infection after exposure and is not recommended for that purpose.
