Measles Vaccine Recommendations

Measles can be prevented with MMR vaccine. The vaccine protects against three diseases: measles, mumps, and rubella. 

Who should get MMR (Measle-Mumps-Rubella) vaccine?

Children

CDC recommends all children get two doses of MMR vaccine, starting with the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age. Children can receive the second dose earlier as long as it is at least 28 days after the first dose.

Learn about MMRV vaccine, which protects against measles, mumps, rubella, and varicella (chickenpox). This vaccine is only licensed for use in children who are 12 months through 12 years of age.

Students at post-high school educational institutions

Students at post-high school educational institutions who do not have presumptive evidence of immunity need two doses of MMR vaccine, separated by at least 28 days.

Adults

Adults who do not have presumptive evidence of immunity should get at least one dose of MMR vaccine.

Certain adults may need 2 doses. Adults who are going to be in a setting that poses a high risk for measles or mumps transmission should make sure they have had two doses separated by at least 28 days. These adults include

  • students at post-high school education institutions
  • healthcare personnel
  • international travelers

International travelers

People 6 months of age and older who will be traveling internationally should be protected against measles. Before any international travel—

  • Infants 6 through 11 months of age should receive one dose of MMR vaccine. Infants who get one dose of MMR vaccine before their first birthday should get two more doses (one dose at 12 through 15 months of age and another dose separated by at least 28 days).
  • Children 12 months of age and older should receive two doses of MMR vaccine, separated by at least 28 days.
  • Teenagers and adults who do not have presumptive evidence of immunity against measles should get two doses of MMR vaccine separated by at least 28 days.

Is getting vaccinated the best way to prevent measles?

Getting the measles vaccine is the best way to prevent measles.

There is no link between vaccines and autism.  Scientists in the United States and other countries have carefully studied the MMR shot.  No studies have found a link between autism and the MMR shot

How effective is the measles vaccine?

The measles vaccine is very effective. One dose of measles vaccine is about 93% effective at preventing measles if exposed to the virus. Two doses are about 97% effective.

My child is too young to get the measles vaccine. How can I protect them from getting measles?

Your child may be too young to get the measles vaccine, but you can protect them by making sure everyone who lives in or visits your home is vaccinated. Avoid people who are sick with measles. Talk to your health care provider. Your child may benefit from immunoglobulin (IG) if they have been around someone who has measles.

What should I do if I'm not sure I was vaccinated against measles?

Check with your health care provider. If you were born before 1957 it's likely that you have been exposed to the virus and are immune. If you were born between 1957 and 1971, the vaccine you received may not have been as reliable. Ask your doctor if you've been properly vaccinated.

Can I still get measles if I am fully vaccinated? 

Very few people—about three out of 100—who get two doses of measles vaccine will still get measles if exposed to the virus. Experts aren’t sure why. It could be that their immune systems didn’t respond as well as they should have to the vaccine. But the good news is, fully vaccinated people who get measles seem more likely to have a milder illness. And fully vaccinated people seem also less likely to spread the disease to other people, including people who can’t get vaccinated because they are too young or have weakened immune systems.

Do I ever need a booster vaccine for measles?

No. CDC considers people who received two doses of measles vaccine as children according to the U.S. vaccination schedule protected for life, and they do not ever need a booster dose.

If you’re not sure whether you are fully vaccinated, talk with your healthcare provider.
