MMR Vaccine Requirement for Immigration

The MMR vaccine — which protects against measles, mumps, and rubella — is required for all immigration applicants who do not have documentation of two doses of MMR vaccine or laboratory evidence of immunity to all three diseases. USCIS places particular emphasis on measles immunity due to ongoing public health concerns about measles outbreaks. Applicants born before 1957 may be considered immune to measles and mumps based on presumed prior exposure, but rubella immunity must still be documented.

Two-Dose Requirement

ACIP recommends two doses of MMR vaccine for most individuals. For immigration purposes, USCIS requires documentation of two doses. If you have records showing only one dose, you will need to receive a second dose. The second dose can be administered as soon as 28 days after the first.

If you have no MMR vaccination records at all, you will need either titer testing to demonstrate immunity or two doses of MMR vaccine. Our civil surgeon will advise you on the most efficient approach.

Titer Testing for MMR

Titer blood tests are available for measles, mumps, and rubella individually. If your titer results demonstrate adequate immunity to all three diseases, the MMR vaccination requirement is satisfied. If your titer shows immunity to some but not all three diseases, you may still need to receive the MMR vaccine, as it is administered as a combined vaccine. Separate component vaccines are not routinely available.

Special Considerations for Measles

Measles immunity receives heightened attention from USCIS due to the highly contagious nature of measles and ongoing outbreaks in various parts of the world. Applicants from countries with lower vaccination rates may face additional scrutiny. Ensuring you have documentation of two MMR doses or a positive measles titer is particularly important.

MMR Vaccine Safety and Contraindications

The MMR vaccine is a live attenuated vaccine, which means it contains weakened forms of the measles, mumps, and rubella viruses. It is contraindicated for individuals who are pregnant, severely immunocompromised, or have had a severe allergic reaction to a prior MMR dose or vaccine component. If you have any of these conditions, inform the civil surgeon before your appointment so that appropriate documentation can be prepared.
