Measles Immunization

Measles, Mumps, Rubella (MMR) Vaccine

The best way to protect against measles is by getting the measles, mumps, and rubella (MMR) vaccine. The MMR vaccine is safe, effective, and has been used for decades.

Routine schedule: 

• 1st dose: 12-15 months old
• 2nd dose: 4-6 years old

Non-routine schedule:

“Non-routine” refers to MMR vaccine administration that falls outside the standard routine childhood immunization schedule. Two doses, at least 28 days apart, are recommended for healthcare workers, international travelers, and college students.

Key Points:

• The MMR vaccine provides lifelong protection for most people
• Immunity can fade in rare cases
• Mild side effects (like low fever or sore arm) are possible and go away on their own
• There is no link between MMR vaccine and autism spectrum disorder. This has been confirmed by multiple large studies worldwide. For more information visit: https://www.cdc.gov/autism/faq/index.html

Not Sure You’re Vaccinated?

Check your vaccination records, contact your healthcare provider or local health department to check your available past immunization history. 

If you don’t have proof of receiving the MMR vaccine, you should get vaccinated. It’s safe to get another dose, even if you might already be immune.

• If you got the vaccine in the 1960s:
  1. If you had the live vaccine, you are likely protected
  2. If you had the inactivated/unknown vaccine or type, consider getting revaccinated
• If you’re unsure about past doses, you may still need 1 or 2 MMR doses
• Older kids, teens, and adults may need 1 or 2 doses, depending on their vaccination history
• Doses should be spaced at least 28 days apart, if two MMR doses are recommended
