Measles (MMR) Vaccine Schedule: Recommended Ages for Children

CDC recommends two-dose MMR (measles, mumps, rubella) schedule:

  • Dose 1: 12–15 months old.
  • Dose 2: 4–6 years old (before school entry).

Special Circumstances

  • Early dose (6–11 months): International travel, outbreak exposure. Does not count toward routine series; repeat at 12–15 months.
  • Catch-up: Unvaccinated children/adolescents: 2 doses ≥4 weeks apart.
  • Adults born ≥1957: 1 dose if no evidence of immunity; 2 doses for high-risk (healthcare, students, travelers).

MMR is 97% effective after two doses. Contraindications: severe immunodeficiency, pregnancy, anaphylaxis to prior dose/components.
