Protect yourself against measles
The best way to protect yourself and your loved ones is by getting the measles, mumps, and rubella (MMR) vaccine. You should plan to be fully vaccinated against measles at least 2 weeks before you depart. If your trip is less than 2 weeks away and you're not protected, you should still get a dose of MMR. The MMR vaccine protects against all 3 diseases.
- Two doses of MMR vaccine provide 97% protection against measles.
- One dose provides 93% protection.
Call your doctor or your local health department; or locate a health center or clinic near you to schedule an appointment for the MMR vaccine. CDC does not recommend measles vaccine for infants younger than 6 months of age.
Infants under 12 months old who are traveling
- Get an early dose at 6 through 11 months.
- Follow the recommended schedule and get:
- Another dose at 12 through 15 months.
- A final dose at 4 through 6 years.
- Another dose at 12 through 15 months.
Teens & adults with no evidence of immunity*
- Get first dose immediately.
- Get second dose 28 days after first dose.
*Acceptable evidence of immunity against measles includes at least one of the following:
- Written documentation of adequate vaccination
- Laboratory evidence of immunity
- Laboratory confirmation of measles
- Birth in the United States before 1957
After international travel
Watch your health for 3 weeks after you return. Measles is highly contagious and can spread to others through coughing and sneezing.
Call your doctor immediately if:
- If one person has measles, 9 out of 10 people around that person will also become infected if they are not protected.
- People who are infected can spread measles to others from 4 days before a rash develops through 4 days after the rash appears.
- Measles symptoms typically include:
- High fever (may spike to more than 104° F)
- Cough
- Runny nose (coryza)
- Red, watery eyes (conjunctivitis or pink eye)
- Rash (3-5 days after symptoms begin)
- High fever (may spike to more than 104° F)

U.S. measles outbreaks from international travel
In the United States, measles cases originate from international travel.
The disease is brought into the United States by unvaccinated people who get infected in other countries. Typically, 2 out of 3 of these unvaccinated travelers are Americans. They can spread measles to other people who are not protected against measles, which sometimes leads to outbreaks.
Since measles is still common in many countries, unvaccinated travelers bring measles to the United States, and it can spread. Protect yourself, your family, and your community with the MMR vaccine, especially before traveling internationally.
