MMR Vaccine Options for a 35-Year-Old Adult

For a 35-year-old adult, either M-M-R II (Merck) or PRIORIX (GlaxoSmithKline) are appropriate MMR vaccine options, as both are fully interchangeable and recommended for adults who need MMR vaccination. 1

Available MMR Vaccines

  • M-M-R II (manufactured by Merck) has been available in the United States since 1978 1
  • PRIORIX (manufactured by GlaxoSmithKline) was approved by the FDA in June 2022 as a second MMR vaccine option 1
  • Both vaccines contain live attenuated strains of measles, mumps, and rubella viruses that are genetically similar or identical 1
  • The Advisory Committee on Immunization Practices (ACIP) considers both vaccines to be fully interchangeable for all indications 1

Administration for Adults

  • Adults born in 1957 or later who do not have evidence of immunity should receive at least one dose of MMR vaccine 1
  • For adults without documentation of vaccination or evidence of immunity, two doses of MMR vaccine administered at least 28 days apart are recommended 1, 2
  • Both vaccines are administered as a subcutaneous injection 1

Specific Recommendations for 35-Year-Olds

  • A 35-year-old should have documentation of having received at least one dose of MMR vaccine on or after their first birthday, documentation of physician-diagnosed disease, or laboratory evidence of immunity 1
  • If the 35-year-old is at higher risk (healthcare worker, international traveler, or during an outbreak), two doses of MMR vaccine are recommended 1
  • If vaccination history is unknown or uncertain, the adult should be considered unvaccinated and should receive appropriate vaccination 1

Interchangeability of Vaccines

  • PRIORIX and M-M-R II are considered fully interchangeable by ACIP 1
  • Studies have shown that PRIORIX is safe and immunogenic when administered as a second dose after M-M-R II 1
  • Either vaccine may be administered in any situation in which an MMR virus-containing vaccine is indicated 1

Contraindications and Precautions

  • Both vaccines are contraindicated in persons with history of severe allergic reactions to any component of the vaccine 1
  • Neither vaccine should be administered to pregnant women or severely immunocompromised individuals 1
  • Additional live virus vaccines not administered on the same day should be separated by at least 28 days 1

Clinical Pearls

  • Having two interchangeable MMR vaccines from different manufacturers helps safeguard vaccine supply in the United States 1
  • MMR vaccination is particularly important for adults born after 1957 who lack evidence of immunity, as they remain at risk for these diseases 1
  • The availability of multiple vaccine options improves access to this important preventive measure 1
