The MMR (measles, mumps and rubella) vaccine was added to New Zealand’s National Immunisation Schedule in 1990 , replacing the earlier single‑antigen measles vaccine for infants.

Quick Scoop: Key Facts

  • The combined MMR vaccine started in NZ in 1990 for all infants at about 12–15 months of age.
  • Before that, New Zealand used separate measles and rubella vaccines at different ages, with measles vaccine used for children and rubella vaccine targeted mainly at girls.
  • In 1992 , a second dose of MMR was introduced for 11‑year‑olds, and later schedule tweaks moved the second dose down to preschool age to improve early protection.

How the Schedule Evolved

  • 1990: MMR introduced at 12–15 months, replacing the single measles vaccine.
  • 1992: Second MMR dose added at age 11 years for both boys and girls.
  • 2001: Second dose shifted from age 11 to age 4 years, with school catch‑up for 5–10‑year‑olds.
  • 2020s: The timing of the two routine doses was adjusted again (first dose at 12 months, second at 15 months) to give earlier full protection in childhood.

Why This Matters Now

  • New Zealand has had several measles outbreaks (for example, major ones in the 1990s and in 2019), which highlighted immunity gaps in people who missed doses or were born in transition years.
  • Because MMR has been on the schedule since 1990, people born from 1990 onward are expected to have had at least one, and usually two, doses—though individual records sometimes show missed vaccinations.

If You’re Checking Your Own Status

  • If you were born before 1990, you may have had single measles or rubella vaccines rather than MMR, or no doses at all, depending on age and uptake at the time.
  • Current NZ guidance allows funded catch‑up MMR for many people born from 1969 onwards who do not have documented evidence of two doses, so uncertain adults can often just get vaccinated again.
