COVID-19 Vaccines

Third dose eligibility

As an additional measure to continue protecting Ontario’s most vulnerable, based on the recommendation of the Chief Medical Officer of Health and other health experts, the province offers third doses of the COVID-19 vaccine to those at highest-risk.

• Before booking your appointment for your third dose PLEASE CHECK WITH YOUR HEALTH CARE PROVIDER to make sure you receive your dose at the right time.
• Third doses are given by appointment only.
• Evidence continues to show that a complete two-dose COVID-19 vaccine series provides strong protection against COVID-19 infection and severe outcomes, including against the Delta variant, in the general population. 

Booster shots are available to higher-risk populations 6 MONTHS after their last dose

• Individuals 70 years of age and over (born in 1951 or earlier)
• Health care workers and designated essential caregivers in congregate settings (including long-term care home and retirement home staff and designated caregivers). These individuals should consult their employers for vaccination options.
• Individuals who received a complete series of a viral vector vaccine (two doses of the AstraZeneca vaccine or one dose of the Janssen vaccine)
• First Nation, Inuit and Métis adults and their non-Indigenous household members.
• Residents of high-risk congregate settings including long-term care homes, higher-risk licensed retirement homes and First Nations elder care lodges

Offering the extra layer of protection provided by a booster dose will contribute to the fight against COVID-19, but third doses are NOT required to meet the provincial proof of vaccine mandate to enter some commercial establishments. 

Third doses are available to highest-risk populations 2 MONTHS after their last dose

• Those undergoing active treatment for solid tumors
• Those who are in receipt of chimeric antigen receptor (CAR)-T-cell
• Those with moderate or severe primary immunodeficiency (e.g., DiGeorge syndrome, Wiskott-Aldrich syndrome)
• Those with Stage 3 or advanced untreated HIV infection and those with acquired immunodeficiency syndrome
• Those undergoing active treatment with the following categories of immunosuppressive therapies: anti-B cell therapies (monoclonal antibodies targeting CD19, CD20 and CD22), high-dose systemic corticosteroids (refer to the CIG for suggested definition of high dose steroids), alkylating agents, antimetabolites, or tumor-necrosis factor (TNF) inhibitors and other biologic agents that are significantly immunosuppressive.
• Transplant recipients (including solid organ transplant and hematopoietic stem cell transplants)
• Patients with hematological cancers (examples include lymphoma, myeloma, leukemia) on active treatment (chemotherapy, targeted therapies, immunotherapy)
