Change in Ontario Immunization Schedule for Infants and Children

Ontario has recently expanded its publicly funded immunization program to include the following additional vaccines:

August 2011

rotavirus vaccine (Rotarix™) that protects against a virus that causes severe vomiting, diarrhea and dehydration in infants.  This vaccine is a liquid and is given by mouth. 

A combined measles-mumps-rubella-varicella (MMRV- Priorix-Tetra™) vaccine is also being offered between the ages of 4-6 years.  MMRV vaccine will complete the recommended 2 dose series for the measles-mumps-rubella (MMR) vaccine received at 12 months of age and the chickenpox (Varicella) vaccine received at 15 months of age.

All children born after January 1st, 2000 are now eligible to receive two doses of varicella containing vaccine if needed to complete the recommended two dose series.

November 2010

The introduction of an enhanced pneumococcal vaccine program in November 2010 resulted in a slight change to the infant immunization schedule in Ontario. Most infants in Ontario will now receive only three doses of pneumococcal vaccine. Infants with medical conditions that put them at high risk for pneumococcal disease will follow a four dose schedule. 

The pneumococcal vaccine that infants will now receive (Prevnar® 13), will protect against three additional strains of the disease.  There are many strains of pneumococcal disease which is the leading cause of bacteremia (bacteria in the blood stream), meningitis, bacterial pneumonia and acute otitis media (ear infections) in children.

Publicly funded immunization schedule for infants and children as of August 2011:

Routine immunization schedule for infants and children begins at two months of age. It is safe to provide three or more vaccines at the same visit. When multiple vaccines are provided at the same visit they are given in different locations. For infants and children over 2 months of age the new publicly funded vaccines will be provided as appropriate. The vaccine schedule is listed below and is also available in chart form:
