Information About Adult Measles Immunity


As you have seen in the news, there have been several outbreaks of measles in the United States.  Measles had previously been considered an eradicated illness in this country due to very effective vaccination programs.  Unvaccinated people have brought new cases into the population and that has raised questions about adult immunity. 


The CDC guidance on immunizing adults is that the following people are considered immune to measles:

Acceptable presumptive evidence of immunity against measles includes at least one of the following:

  1. written documentation of adequate vaccination:
    • one or more doses of a measles-containing vaccine administered on or after the first birthday for preschool-age children and adults not at high risk
    • two doses of measles-containing vaccine for school-age children and adults at high risk, including college students, healthcare personnel, and international travelers
  2. laboratory evidence of immunity
  3. laboratory confirmation of measles
  4. birth before 1957


Questions about your own level of immunity?

We suggest the following options:


  • We can check your immunity with a blood test.  This test is not typically covered by insurance, as insurance generally requires that the requested test be associated with a  particular diagnosed illness.  Since we have the ability to order tests directly through LabCorp, we are able to get that test for $30. 
  • You can get an MMR booster at the pharmacy, which we can order for you.
