For parents, the vaccination schedule for children can be challenging to follow, especially in the first few years of life, when multiple immunization appointments are required. In Ontario, however, the recommended schedule is designed to follow a child\u2019s developmental needs at the ages when they are most vulnerable to vaccine-preventable infections.<\/p>\n\t\t\t\t\t

Vaccines are administered according to the developmental stage, the likelihood of exposure, and the need for booster doses. Some vaccines can provide protection against multiple infections, while others are given later in childhood or adolescence when immunity is most needed. Parents in Etobicoke should always refer to the standard Ontario vaccination schedule and consult with a medical professional about their child\u2019s individual needs. Children who have fallen behind, are new to Ontario, have chronic conditions, weakened immunity, or plan to travel internationally may require a different schedule.<\/p>\n\t\t\t\t\t

Important Information for Parents<\/h3>\n\t\t\t\t\t

The Ontario vaccination schedule recommends that children be immunized starting at approximately 2 months of age. Important vaccines are typically administered at around 2, 4, 6, 12, 15, and 18 months. Children receive booster doses between the ages of 4 and 6 years. Additional publicly funded vaccines are recommended at around Grade 7, while adolescents receive a tetanus, diphtheria and pertussis booster between 14 and 16 years of age.<\/p>\n\t\t\t\t\t

As of August 2026, the province recommends that children 6 months and older receive seasonal influenza and COVID-19 vaccination according to the current recommendations for Ontario. A child falling behind on the vaccination schedule will typically not have to restart the series from the beginning. Parents of Toronto students should note that it is their responsibility to report immunization records to Toronto Public Health. Children with chronic conditions or traveling outside the country may need additional vaccines. Parents should review their child\u2019s immunization record at every opportunity rather than waiting until school entry or when a physician\u2019s note is required.<\/p>\n\t\t\t\t\t

Health Canada and the Public Health Agency of Canada stress that childhood vaccination schedules are designed to help protect children at the ages when they are most vulnerable and to ensure that immunity is maintained through booster doses.<\/p>\n\t\t\t\t\t

Why Following the Childhood Vaccination Schedule Is Important<\/h3>\n\t\t\t\t\t

Vaccination typically involves the administration of an antigen or other vaccine components to stimulate the development of immunity to a particular infection. When exposed to the causative agent, the child\u2019s immune system will recognize it and mount an appropriate response, potentially reducing the severity of the infection. For more general information on vaccination, parents may want to review the overview on Wikipedia. In practice, however, it is essential to rely on the individual recommendations of a medical professional.<\/p>\n\t\t\t\t\t

The timing of individual vaccines is critical, as some childhood infections can be especially severe before a child starts school. This is why some vaccines are recommended before the age of 2 years rather than later, when a child is in a daycare or a school setting. Furthermore, some infections require more than 1 dose of vaccine, as the first dose typically elicits only a partial immune response, while subsequent doses are required to boost the level of protection.<\/p>\n\t\t\t\t\t

Booster doses do not mean that the initial vaccine series was ineffective. The immune response to some vaccines can simply diminish over time, particularly when a child grows older and their immune system matures. A booster dose re-exposes the immune system to the antigen, eliciting a stronger response. For parents who are unsure if their child has received all recommended doses, an appointment with a local family doctor<\/a> can help review the child\u2019s vaccination records and medical history.<\/p>\n\t\t\t\t\t

Ontario Childhood Vaccination Schedule: The Basic Series<\/h3>\n\t\t\t\t\t

The Ontario vaccination schedule is designed to follow children throughout their development, starting from infancy. At approximately 2 months of age, babies receive their first dose of the diphtheria, tetanus, pertussis, polio, and Haemophilus influenzae type b (Hib) combination vaccine. At the same age, pneumococcal and rotavirus vaccines are also introduced. Similar immunization, including the combination diphtheria-tetanus-pertussis-polio-Hib vaccine, is typically given at 4 months. At 6 months, children receive another dose of the combination vaccine, this time without Hib.<\/p>\n\t\t\t\t\t

At 12 months, the childhood vaccination schedule includes measles, mumps, and rubella (MMR) vaccine, meningococcal conjugate vaccine, and another pneumococcal vaccine. At 15 months, children receive varicella or chickenpox vaccine. At 18 months, they get another dose of the combination diphtheria-tetanus-pertussis-polio-Hib vaccine. Parents can also discuss developmental, nutritional, and other health concerns with the doctor at each immunization appointment.<\/p>\n\t\t\t\t\t

Between 4 and 6 years of age, children receive a booster dose of the tetanus, diphtheria, pertussis, and polio vaccine, as well as a combined MMR and varicella booster. In Grade 7, publicly funded vaccines include meningococcal-ACYW, hepatitis B, and HPV vaccines. Adolescents typically receive another dose of the Tdap vaccine between 14 and 16 years of age.<\/p>\n\t\t\t\t\t
