Measles, Mumps, Rubella (MMR) Vaccine

The MMR vaccine, also called the measles vaccine, is a combination of three vaccines in a single shot – protecting you against measles, mumps and rubella. It plays a major role in keeping people safe from three potentially serious viral illnesses as well as preventing widespread outbreaks and promoting lasting health.

What is the Measles, Mumps, Rubella (MMR) Vaccine?

Measles, mumps and rubella are serious childhood illnesses that can cause significant complications. Almost everyone who hasn’t had the MMR vaccine will get sick if they're exposed to these viruses. Another version of this vaccine is the MMRV, which also includes the varicella (chickenpox) vaccine. MMRV is offered to children between the ages 12 months to 12 years.

When Do You Get the MMR Vaccine?

The Centers for Disease Control (CDC) and Prevention recommend the following MMR vaccine schedule:

  • First dose: 12-15 months
  • Second dose: 4-6 years old

Additional doses of the MMR vaccine are recommended for adults and children traveling internationally and those unsure of their vaccination status. Individuals born before 1957 are generally presumed to be immune regardless of vaccination status. If you’re unsure if you or your child has received the MMR vaccine, talk to your doctor.

How Long Does the MMR Vaccine Last?

The MMR vaccine lasts most people their entire lives. Two doses are 97% effective at preventing measles, 86% effective at preventing mumps and 97% effective at preventing rubella.

What are the Side effects of the MMR Vaccine?

Side effects of the MMR vaccine are typically mild and last for a few days. You may experience any of the following:

Severe side effects are rare and receiving the MMR vaccine is much safer than getting measles, mumps or rubella. Seek immediate medical attention if you experience an allergic reaction or severe side effects.

When did the MMR Vaccine Come Out?

The MMR vaccine has been available in the United States for more than 60 years.

Is MMR a Live Vaccine?

Yes, the MMR vaccine contains weakened live viruses. This means the MMR shot won’t give you the full-blown illness if you have a healthy immune system. Instead, it'll teach your body to recognize the viruses and develop a response to fight them off if you’re ever exposed. Because the MMR vaccine contains live viruses, there's a small percentage of the population who shouldn’t receive it due to pregnancy or a weakened immune system. Talk to your doctor if you have questions about whether you, or your child, should receive the MMR vaccine.

What Happens if a Child Doesn’t Receive the MMR Vaccine?

The MMR Vaccine helps keep children healthy, reducing the likelihood of missing school and you missing work to care for them. If a child doesn’t receive the MMR vaccine, they're at higher risk of serious complications, such as brain inflammation, deafness, blindness and death. Being vaccinated also helps limit the size, duration and spread of measles, mumps and rubella outbreaks.
