On August 17, 2021, the province announced updates to COVID-19 vaccine eligibility to protect individuals most at risk of serious illness from the virus. Ontario’s Updated COVID-19 Vaccination Eligibility | Ontario Newsroom
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. However, for some populations, a third dose may be required to provide sufficient protection based on a suboptimal or waning immune response to vaccines and increased risk of COVID-19 infection.
Certain immunocompromised individuals eligible for third doses are:
- 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) for malignant hematologic disorders
- Recipients of an anti-CD20 agent (e.g. rituximab, ocrelizumab, ofatumumab)
Individuals in these groups are eligible to receive their third dose at a minimum of eight weeks following their second dose and will be contacted by their health care provider such as their primary care provider, specialist, or their hospital specialty program. Individuals unable to receive the vaccine from their providers can ask for a form from them indicating the patient’s eligibility. The form can be taken to participating physicians, who will administer the vaccine.
Immunocompromised clients who are unable to access a third-dose vaccine from their healthcare provider may attend any of the vaccine clinics hosted by the Grey Bruce Health Unit. No appointment is necessary. Clients must be eligible in the categories described above and must provide the written provincial documentation signed by their physician, including the physician’s CPSO number. No other document or attestation will be accepted.
