  • MMR (Measles, Mumps, and Rubella)
  • Vaccine Recommendations

Under what circumstances should adults be considered for testing for measles-specific antibody prior to getting vaccinated?

Adults without evidence of immunity and no contraindications to MMR vaccine can be vaccinated without testing. Only adults without evidence of immunity might be considered for testing for measles-specific IgG antibody, but testing is not needed prior to vaccination.

CDC does not recommend measles antibody testing after MMR vaccination to verify the patient’s immune response to vaccination.

Two documented doses of MMR vaccine given on or after the first birthday and separated by at least 28 days is considered proof of measles immunity, according to ACIP. Documentation of appropriate vaccination supersedes the results of serologic testing for measles, mumps, rubella, and varicella.
