Ontario’s Chief Medical Officer of Health has announced third doses of COVID-19 vaccine are now available to specific vulnerable populations. The third dose will provide those with highest-risk health conditions an improved immune response against COVID-19.
You may register for a third dose of COVID-19 vaccine if you have one of the following highest-risk health conditions:
- Individuals receiving active treatment (e.g., chemotherapy, targeted therapies, immunotherapy) for solid tumor or hematologic malignancies. Active treatment includes patients who have completed treatment within 3 months.
- Recipients of solid-organ transplant and taking immunosuppressive therapy.
- Recipients of chimeric antigen receptor (CAR)-T-cell therapy or hematopoietic stem cell transplant (within 2 years of transplantation or taking immunosuppression therapy).
- Individuals with moderate to severe primary immunodeficiency (e.g., DiGeorge syndrome, Wiskott-Aldrich syndrome).
- Individuals with Stage 3 or advanced untreated HIV infection and those with acquired immunodeficiency syndrome.
- Individuals receiving 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. Active treatment for patients receiving B-cell depleting therapy includes patients who have completed treatment within 12 months.
For medically eligible, third doses may be scheduled a minimum of eight weeks (56 days) after the date of an individual’s second dose. To verify the date of your second dose you can visit https://covid19.ontariohealth.ca/ and sign in using your green photo health card.
***Note: If the above conditions are not met you may be turned away at the clinic.
- Residents of high-risk congregate settings including long-term care homes, higher-risk licensed retirement homes and First Nations elder care lodges are also eligible for a third dose.
- Residents of these facilities will receive vaccinations onsite and do not need to book an appointment.
- For Long Term Care, High Risk Retirement and First Nations elder care residents, the third dose should be scheduled a minimum of 5 months after the second dose.
- For a retirement home to be deemed “high-risk” it must be directly attached to a long-term care home facility. The only high-risk retirement homes in the County of Lambton are Vision, Fiddicks, and Twin Lakes Terrace.
