Immunization Schedule

Child getting a vaccination  
Immunizations protect your child against several serious, life-threatening infectious diseases. Your child should have "shots" according to the schedule recommended for your province, state, or country. For more specific information, contact your child's physician, or the local public health nurse for your community.

The following is the recommended schedule of immunizations during childhood for the province of Ontario as of March 2013. For the most current recommen​dations according to the National Advisory Committee on Immunization and for each province and territory go to the Public Health Agency of Canada website.

Reasons not to vaccinate

If any of the following conditions apply to your child, talk to your doctor before getting your child vaccinated.

  • Your child had an allergic reaction to a previous vaccination.
  • Your child has seizures or serious neurological disease.
  • Children who are immunocompromised should not be given live virus vaccines such as chickenpox or MMR. Because live virus vaccines live and divide within the person vaccinated, they can cause the actual disease if the immune system is very weak.
  • Your child has egg allergies. There are several types of flu vaccines. Some of these vaccines could cause an allergy if your child is allergic to eggs while others do not. If your child has a severe allergy to eggs, talk to their doctor about whether or not to get the influenza vaccine and, if so, which one to get. Children who are allergic to eggs can receive all routine immunizations.

Unwarranted reasons not to vaccinate

Unnecessary precautions have led some parents to postpone or cancel scheduled immunizations. A child can still be immunized even if:

  • the child had soreness, redness, or swelling at the injection site after a previous DTaP shot
  • the child had a fever of less than 40.5°C (105°F) after a previous DTaP shot
  • the child has a mild illness such as a cold, cough or diarrhea without a fever
  • the child is recovering from a mild illness such as a cold, cough or diarrhea
  • the child has recently been exposed to an infectious disease
  • the child is taking antibiotics
  • the child was premature
  • the child's mother is pregnant
  • the child is breastfeeding
  • the child has allergies (with the exception of the influenza vaccine as explained above)
  • the child's family has a history of convulsions or sudden infant death syndrome (SIDS)
