COVID‑19 vaccines

Overview

COVID-19 is a respiratory illness that can cause mild to severe illness, with similar symptoms to the flu and Respiratory Syncytial Virus (RSV). Getting your annual COVID-19 vaccine is the best way to remain protected against the most severe outcomes of COVID-19 infection, including hospitalization and death.

To keep you and your loved ones protected, it is recommended you get the updated COVID-19 vaccine annually each fall.

Vaccination may not always prevent symptomatic infection but it can help prevent severe illness and lower your chances of developing long-term symptoms after you have recovered, like those caused by post COVID-19 condition (commonly known as long COVID).

Annual COVID-19 vaccine program

Ontario’s COVID-19 vaccine program has transitioned to an annual program in alignment with expert recommendations from the National Advisory Committee on Immunization (NACI).

Like Ontario’s flu program, everyone aged 6 months and older who lives, works or goes to school in Ontario will be eligible for COVID-19 vaccination each fall.

Co-administration

It is safe to receive the annual COVID-19 vaccine and flu shot, and the RSV vaccine for eligible older adults, at the same time.

When you should get your fall dose

Everyone aged 6 months of age and older who lives, works or goes to school in Ontario may receive their COVID-19 vaccine dose(s) starting on October 27, 2025.

If you are a part of any of the following groups, you may receive your COVID-19 vaccine dose(s) and flu shot as soon as they become available in the fall (ahead of October 27, 2025):

• specific populations at high-risk of infection
• children 6 months to 4 years of age
• individuals with significant exposure to birds or mammals through interactions with birds or mammals (such as poultry, livestock, slaughterhouse and processing plant workers, wildlife officers/researchers, and veterinarians)
• those at increased risk of exposure or severe outcomes including:
  • residents in long-term care homes and other congregate living settings who are aged 17 years and under
  • pregnant individuals
  • individuals from First Nations, Métis and Inuit communities who are aged 54 years and under
  • members of racialized and other equity-denied communities
  • health-care workers and other care providers in facilities and community settings as per NACI

Specific populations at high-risk of infection

If you are included in the specific high-risk populations below, it is recommended that you receive a COVID-19 vaccine dose(s) as soon as it becomes available in the fall and should receive an additional dose in the spring. High-risk groups eligible for both fall and spring dose(s) include:

• adults 65 years of age and older
  • National Advisory Committee on Immunization (NACI) recommends that those 80 years and older should receive an additional dose of vaccine while those 65 to 79 years of age may receive an additional dose of vaccine in the spring.
• adult residents of long-term care homes and other congregate living settings for seniors
• individuals 6 months of age and older who are moderately to severely immunocompromised (due to an underlying condition or treatment)
• individuals 55 years and older who identify as First Nations, Inuit, or Métis and their non-Indigenous household members who are 55 years and older

People who are moderately to severely immunocompromised

People with the following conditions are considered to be moderately to severely immunocompromised and should receive both fall and spring doses:

• solid tumour or hematologic malignancies or treatments for these conditions
• solid-organ transplant and taking immunosuppressive therapy
• hematopoietic stem cell transplant (HSCT) (within 2 years of transplantation or taking immunosuppression therapy)
• immunocompromised due to chimeric antigen receptor (CAR) T cell therapy targeting lymphocytes
• moderate to severe primary immunodeficiency with associated humoral and/or cell-mediated immunodeficiency or immune dysregulation
• HIV with AIDS-defining illness or TB diagnosis in last 12 months before starting vaccine series, or severe immune compromise with CD4 ‹ 200 cells/µL or CD4<15%, or without HIV viral suppression
• recent treatment with the following categories of immunosuppressive therapies:
  • anti-B cell therapies (monoclonal antibodies targeting CD19, CD20 and CD22)
  • high-dose systemic corticosteroids
  • alkylating agents
  • antimetabolites
  • tumor-necrosis factor (TNF) inhibitors
  • other biologic agents that are significantly immunosuppressive
• chronic kidney disease on dialysis

Contact your health-care provider if you have received any of the following since your most recent COVID-19 vaccination(s):

• a hematopoietic stem cell transplant
• hematopoietic cell transplant (autologous or allogeneic)
• a (CAR)-T-cell therapy

You may be recommended to be re-vaccinated due to loss of immunity following transplant or therapy.

COVID-19 vaccination timing

Learn more about completing your initial COVID-19 vaccine series and when you should get your COVID-19 vaccination based on if you:

• have completed your initial series of COVID-19 vaccinations
• have tested positive for COVID-19
• are pregnant or breastfeeding

Completing your initial series of COVID-19 vaccinations

Everyone who lives, works or goes to school in Ontario may start or complete their initial series in the fall. Specific high-risk populations may start or complete their initial series in the spring if needed.

What is needed for your initial series of vaccines designed to give a primary antibody response depends on your age and previous COVID-19 vaccinations. It is typically:

• 1 dose for those aged 5 years and over
• 2 doses for those aged 6 months to 4 years

As indicated by NACI, if you are considered to be moderately to severely immunocompromised, it is recommended that you receive additional dose(s) when completing your initial series.

A health-care provider can advise on the appropriate interval between doses.

If you are unsure if you have completed your initial series, you should discuss your COVID-19 vaccination history with a health-care provider or pharmacist, or contact the Provincial Vaccine Contact Centre at  1-833-943-3900.

If you’ve completed your initial series of COVID-19 vaccinations

If you already completed your initial series, it is recommended you receive an updated dose in the fall if it has been at least 3 months (84 days) since your last dose.

If you are part of the specific groups at high-risk of infection, an additional dose is also recommended in the spring.

If you’ve had a COVID-19 infection

If you are at increased risk of COVID-19 and have symptoms, you may be eligible for COVID-19 testing (including PCR and rapid antigen tests).

The guidelines below are for people who have recently tested positive for COVID-19 infection. All others should receive their COVID-19 vaccine according to provincial recommendations.

• If you have completed your initial series, you should wait 3 months following a positive test.
• If you have not started or are completing your initial series and you are:
  • not immunocompromised, you should wait 2 months (56 days) following a positive test
  • immunocompromised, you should wait 1–2 months (28-56 days) following a positive test

People with complex care needs should speak with a health care provider for more information on when to get their next dose following a COVID-19 infection.

If you are pregnant or breastfeeding

Pregnant or breastfeeding individuals should receive an annual COVID-19 vaccine to provide protection during pregnancy and to lower the risk of hospitalization for their newborn.

COVID-19 vaccines may be offered at any trimester and while breastfeeding. There have been no safety concerns with receiving a COVID-19 vaccine during pregnancy or lactation.

COVID-19 vaccination can help protect you from infection. Compared to non-pregnant individuals, COVID-19 infection in pregnancy is associated with:

• increased risk of hospitalization
• increased risk of preterm birth and low birth weight

Additional information is available at:

• The Society of Obstetricians and Gynaecologists of Canada Statement on COVID-19 Vaccination in Pregnancy
• Canadian Immunization Guide (CIG)
• Provincial Council for Maternal and Child Health (PCMCH) COVID vaccine fact sheet

• is immunocompromised due to disease or treatment (to discuss optimal timing for vaccination)
• has had a severe allergic reaction after a COVID-19 vaccination or has an allergy to a component of the COVID-19 vaccine

Read the Canadian Immunization Guide for more information.

If you do not have a health card

If you do not have an Ontario health card, you may use another form of identification (photo identification is required if you are aged 18 or older) to verify your name and date of birth at the time of your appointment, such as:

• a driver’s licence or Ontario photo card
• a passport
• a piece of registered mail, pay stub, student card or library card
• government issued identification from other jurisdictions (including foreign and expired government documents)

If you were vaccinated outside of Ontario

If you received a COVID-19 vaccine outside of Ontario or Canada, you should contact your local public health unit to register your out of province doses if:

• a child is aged 6 months to 4 years and has received 1 or more doses of COVID-19 vaccine outside of Ontario to ensure they have completed the appropriate number of doses for optimal protection
• you are aged 5 years and older and have received 1 or more doses outside of Ontario within the last 6 months, to ensure future doses (if needed) can be given at the appropriate interval

You must provide proof of immunization to your public health unit to register the dose(s). The public health unit may ask for additional proof of vaccination, such as clinic or pharmacy information.

If you applied to have your out of province vaccination(s) registered with your public health unit and are waiting to have it registered, you can call the Provincial Vaccine Contact Centre to book your next vaccine appointment.

Please also bring your out of province vaccination receipts to your next vaccination appointment for validation.

Vaccine types

Only vaccines that Health Canada has approved for use will be administered in Ontario. All COVID-19 vaccines:

• are safe, effective and manufactured with rigorous quality control and assurance
• show a strong immune response and prepare the immune system to fight against COVID-19 and its variants
• significantly decrease the risk of severe outcomes from COVID-19 infection
• significantly decrease the risk of longer-term illness from multisystem inflammatory syndrome in children (MIS-C) and adults (MIS-A), a rare but serious condition that can occur in the weeks following COVID-19 infection

COVID-19 vaccines have varying doses based on an individual’s age and, for those that have not previously received COVID-19 vaccines, immune status. You will be offered an age-appropriate and Health Canada approved vaccine.

It is important to get your annual COVID-19 shot when it becomes available to you. Any of the available COVID-19 vaccines would be preferable to remaining unvaccinated. All COVID-19 vaccines are safe, effective and offer strong protection.

Vaccines for children and youth

Vaccines are safe, effective, and are the best way to remain protected against COVID-19 and its variants. They are an important tool to help prevent serious illness and support the overall health and wellbeing of our children and communities.

It will not interfere with getting other vaccines.

Children and youth who are not up to date on other immunizations can still receive a COVID‑19 vaccine.

If your child is behind on immunizations, we encourage you to contact a health-care provider to get up to date.

Children aged 6 months and older can receive their annual COVID-19 vaccine(s) at the same time as, or at any time before or after, other routine immunizations. Parents and caregivers should discuss vaccination with a health-care provider to determine the best timing for COVID-19 vaccination.
