  • MMR (Measles, Mumps, and Rubella)
  • Scheduling Vaccines

I have an 8-month-old patient who is traveling internationally. The infant needs to be protected from hepatitis A as well as measles, mumps, and rubella. The family is leaving in 11 days. Can I give hepatitis A immune globulin (IG) and MMR vaccine simultaneously?

No. IG may contain antibodies to measles, mumps, and rubella that could reduce the effectiveness of MMR vaccine. For this reason, in February 2018 ACIP voted to recommend that hepatitis A vaccine should be administered to infants age 6 through 11 months traveling outside the United States when protection against hepatitis A is recommended. MMR and hepatitis A vaccines may be safely co-administered to children in this age group. Neither vaccine is counted as part of the child’s routine vaccination series. For details of this recommendation, see the CDC ACIP recommendations for the prevention and control of hepatitis A at, page 18.
