Measles, Mumps & Rubella (MMR)

You may satisfy the Measles, Mumps & Rubella (MMR) requirement in ONE of the following ways: 

1. By vaccine:

  • Two doses of the MMR vaccine (or two doses each of the separate vaccines for measles, mumps, and rubella).
  • Doses must meet the following age/interval requirements:
    • The first dose must be on or after your 1st birthday
    • The second dose must be at least 28 days after the first dose
  • If you only have one dose that meets the age/interval requirements, you still need to get an additional dose.
  • NOTE: since MMR is a live vaccine, it is contraindicated in certain conditions (including if you are pregnant). If you need a medical exemption, see “Exemptions” on the Do I Need to Comply? webpage.


2. By positive titer: 

If you had measles, mumps, and/or rubella, or cannot find records for your past doses of the vaccines:

  • One blood titer each for measles, mumps, and rubella showing evidence of immunity to each.
  • If your titer results do not show evidence of immunity, you will still be required to get any outstanding doses of the vaccine(s) as indicated above.
  • NOTE: When reporting your titer results, remember that "positive" means "positive for immunity" and "negative" means "negative for immunity."
