Facts about Measles for Adults

What is measles?Measles is a highly contagious virus found throughout the world. People get measles by breathing in the measles virus that is spread when an infected person coughs, sneezes, or talks. You can get measles just by being in the same room with an infected person.

Starting in 2011, the US has been experiencing an increase in measles cases related to the increase of measles in foreign countries being visited by US travelers. Recent measles outbreaks of concern have been in Europe, but measles is found throughout the world so all US residents should be immune to measles before international travel.

Symptoms Symptoms of measles include high fever, generalized rash, runny nose, pink, watery eyes, coughing, diarrhea, and earache. The average time between exposure to the measles virus and development of symptoms is usually 10 to 12 days but can range from as few as seven days to as many as 21.

Prevention There is a vaccine to protect against measles. The vaccine is given as part of a combination vaccine, called the MMR vaccine that protects against measles, mumps, and rubella.

Which adults should get vaccinated against measles with MMR vaccine?
  • Adults born in 1957 or later who do not have a medical contraindication should receive at least one dose of the MMR vaccine, unless they have documentation of vaccination with at least one dose of measles-containing vaccine or other acceptable evidence of immunity to the disease. 
  • College and university students, healthcare personnel, and international travelers are at increased risk for measles, and should receive two doses of the MMR vaccine to ensure adequate protection.

Vaccine safety
The MMR vaccine is very safe and highly effective with few side effects. Mild reactions such as fever, redness, or swelling at the injection site have been reported. Adult women may infrequently have joint symptoms like pain and stiffness from the rubella part of the vaccine.

As with any medicine, there are very small risks that serious problems could occur after getting the vaccine. However, the potential risks associated with measles, mumps, and rubella are much greater than the potential risks associated with the vaccine. MMR vaccine should not be given to persons who are pregnant or severely immunosuppressed.
