Who is at risk of getting Measles?

  • Anyone who is not immune to measles.

How do I know if I am Immune?

  • Adults born before 1957 are generally considered immune because they more than likely have had measles disease.
  • Adults and children born after January 1, 1957, are considered immune if: they have had measles disease, or
  • a laboratory test confirming that they have immunity to measles, or
  • they have documentation of a dose of MMR vaccine given after 1968.

NOTE:  Washington State Law requires that children receive a 2nd Measles, Mumps, and Rubella (MMR) vaccination before entry into kindergarten.  A second MMR dose has been required for school aged children since 1992. Many colleges and schools of higher education now require proof of a second MMR for school entry.

Which unvaccinated Individuals are at Increased Risk for Exposure to Measles and should consider vaccination now?

  • Persons attending college and other post-high school educational institutions.
  • Persons working in facilities with a lot of international students, workers or travelers.
  • Persons working in medical facilities.
  • International travelers.
  • Any person who has not had measles vaccine and has not had a history of having had measles disease that has been confirmed by a laboratory test.

Who should not receive the Measles (MMR) Vaccine?

Individuals should not receive the MMR Vaccine if they:

  • have had a severe allergic reaction to a vaccine component or following a prior dose
  • are pregnant
  • are taking medications or have conditions that suppress their ability to fight infections
  • have moderate to severe illness right now
  • have recently received a blood product (within the last three months)

*Studies have demonstrated the safety of MMR in egg-allergic children

What can I do to Prevent Measles?

  • People with a rash illness and fever should limit their contact with others until at least 4 full days have passed since the time their rash first appeared
  • People diagnosed with measles should limit their contact with others until at least 4 full days have passed since the time their rash first appeared.
  • People who are exposed to someone who have measles should contact their health care provider immediately. If they have not been vaccinated, measles vaccine can help prevent infection, if it is given within three days (72 hours) of exposure.
  • Immune globulin, when given within six days of exposure, may help prevent infection for those who cannot receive the MMR vaccine.
