In an emergency, call 911 or seek urgent medical care if your child has trouble breathing; swelling of the lips, tongue, throat, or face; severe weakness or unresponsiveness; a seizure; or any symptoms that feel serious or are rapidly worsening. For a young infant, also seek urgent care for a high or persistent fever, poor feeding, unusual sleepiness, difficulty breathing, dehydration, or if your baby looks very unwell.

General education only

My Immunization Guide provides general, Ontario-focused educational information about childhood and adolescent immunization. It is intended to help parents, caregivers, and capable older youth understand the immunization schedule, school requirements, ingredients, side effects, and next steps so they can have informed conversations with a qualified professional.

This website does not provide medical advice. It does not diagnose, prescribe, provide individualized medical advice, determine legal school compliance, or replace advice from a healthcare provider or local public health unit.

No provider-patient relationship

Use of this website does not create a doctor-patient, nurse-patient, pharmacist-patient, or public-health-client relationship between you and this website or anyone associated with it.

Always confirm with a qualified source

Vaccine timing, eligibility, precautions, and catch-up schedules can vary based on age, previous doses, medical history, allergies, immune status, pregnancy, travel, local public health guidance, and product availability. Schedules, products, and eligibility can also change over time.

Always confirm current details, and any decision about your or your child's immunizations, with a licensed healthcare provider or your local public health unit. Where information here differs from official Ontario or Canadian public health sources, those official sources take precedence.
