Ontario’s COVID-19 Vaccination Eligibility for Boosters
On August 17, 2021, Ontario updated eligibility for the COVID-19 vaccine to protect individuals most at risk of serious illness from the virus. A complete two-dose COVID-19 vaccine series provides strong protection against infection and severe outcomes in the general population. However, for some populations, a third dose may be required to provide sufficient protection.
Ontario will offer third doses of COVID-19 vaccine to select vulnerable populations, including those on anti-CD20 disease modifying therapies such as rituximab, ocrelizumab and ofatumumab. This group also includes residents in high-risk congregate settings, including long-term care homes. For a complete list of the select vulnerable populations currently eligible for a booster, please refer here – link.
A third dose aims to help provide individuals with improved immune response to the virus. Individuals in these groups can receive their third dose at a minimum of eight weeks following their second vaccine dose. Locations and timing for third doses may vary by public health unit based on local considerations, with some beginning as early as this week where opportunities exist. Please speak with your health care provider about the optimal timing of your vaccine with your DMT.
