Protection against measles is especially important for infants travelling internationally or to Alberta and Manitoba.
Measles is one of the most contagious diseases worldwide, and while Canada sees only occasional imported cases and outbreaks, it remains a serious concern in many countries.
The measles-containing vaccine is currently available as MMR (measles-mumps-rubella) or MMRV (measles-mumps-rubella-varicella). Routine childhood immunization in Ontario usually begins at 12 months with the first dose of MMR, followed by a second dose of MMRV at 4-6 years, ideally before school entry. The efficacy of a single dose at 12-15 months is estimated at 85-95%, and almost 100% with a second dose.
For infants travelling to areas where measles is common or experiencing outbreaks:
The MMR vaccine can be given as early as 6 months old.
Infants under 6 months are not eligible for vaccination.
If an early dose is given (6-12 months), two additional doses on/after 12 months are still required to ensure long-lasting immunity.
At Magenta Health, we generally recommend early MMR vaccination for travelling infants to protect against infection, while following Ontario’s standard schedule afterwards.
