Immunization Schedule from Infant to Age 6

Vaccines work by training your immune system to recognize and fight off infections. They give you strong protection from many diseases at every stage of life.

Staying up to date with immunizations helps prevent serious illnesses — including those that can spread quickly in places like schools and child care settings.

All vaccines in Ontario’s routine immunization schedule are free for people who are eligible.
