Immunization for your Children

Why is it important to immunize?

Infants and young children are more susceptible to vaccine preventable diseases because their immune systems are not mature enough to fight all infections. Children who do not get vaccinated are at greater risk if they come in contact with vaccine preventable diseases. It’s important for children to be up-to-date with their vaccinations. Schools are places where infectious diseases are commonly spread. As a parent, you can keep your kids of all ages healthy with routine health care and vaccinations. Vaccines are the safest and most efficient way to guard against some diseases. Postponing vaccines can be harmful because it delays protection.

Following the Ontario routine vaccine schedule is the best way to protect your child.

Which vaccines does my child need?

Infants and Preschoolers
School age and Teens
  • Flu vaccine
    • The flu can cause serious complications in children under five years old. The best way to prevent the flu is to get the flu shot. Unless there’s a medical reason not to, everyone aged 6 months or older can benefit from getting the seasonal flu shot. The flu shot is free for anyone who lives, works, or goes to school in Ontario. Children 6 months to under 9 years old who are getting the flu shot for the first time will need two doses separated by at least four weeks. 

What if my child has missed a shot?

If your child has missed one or more of their vaccines, book an appointment with your doctor or call the Health Unit as soon as possible. We can help you figure out which vaccines your child has already had and which ones are still needed.

Every child should have a yellow card that keeps track of their immunizations.

It’s the parent’s job to keep the card updated, and to report immunizations received by their child to the health unit. Health care providers, including doctors, do not report immunization dates to us. Any time your child receives a vaccination, please contact our immunization line at 519-258-2146 ext. 1222.
