Older people in CHSLD will be the first to be affected, followed by those who live in private residences for the elderly (RPA) and intermediate resources (RI) or family type (RTF).
To be eligible for this booster dose, which should enhance protection against COVID-19, they must have received their second dose in five months.
This information was released by 98.5 FM before being confirmed by Radio-Canada.
The operation to inject this third dose should begin at the same time as the flu vaccination campaign, scheduled for early November.
Quebec had already authorized people who are immunosuppressed or on dialysis to receive a third dose of the COVID vaccine last month. Travelers can also receive one exceptionally.
Studies published this summer concluded that the immunity conferred by two doses of the vaccine begins to wane within a few months of its administration.
In late August, the Quebec Immunization Committee (CIQ) decided not to recommend an additional dose of vaccine to CHSLD residents.
He had justified his decision by evoking the short time since the administration of the second dose, but also low incidence of COVID-19 among these residents and lack of data on the immunogenicity, efficacy and safety of a third dose administered to this population.
Clinical studies currently looking at the immunogenicity of a third dose given as a booster have provided an interval of six to eight months after the second dose, while this second dose was offered to CHSLD residents in Quebec there. Just three or four months agohe wrote at the time.
At the federal level, Canada’s National Advisory Committee on Immunization (NACI) is also content to recommend giving a third dose only to immunosuppressed individuals.
The use of a third dose is not unanimous at this stage of the pandemic, which has already claimed at least 4.75 million victims worldwide.
The WHO called for a moratorium on booster doses this summer while waiting for vaccination to be sufficiently advanced in poor countries.
