Canada’s national immunization panel is recommending Canadians get another COVID-19 booster for the fall if it has been at least six months since their last vaccine shot or since last getting infected with the virus.
The National Advisory Committee on Immunization (NACI) said on Tuesday it was recommending a dose of the new formulation of the COVID-19 vaccine for people in the authorized age groups.
“Vaccine manufacturers are developing updated formulations of COVID-19 vaccines to provide better protection against currently circulating variants,” NACI said in its updated recommendations on July 11. “These vaccines are expected to be available in the coming months.”
NACI said additional doses are particularly important for people older than 65 years of age, residents of long-term care homes, pregnant people and people who are high risk due to an underlying medical condition. It also strongly recommended the boosters for First Nations, Métis and Inuit communities, members of racialized communities and essential workers.
“NACI anticipates that new COVID-19 vaccine formulations could be available this fall, and the committee is recommending that jurisdictions plan to offer a dose of the new vaccine if it has been at least six months since a previous dose of vaccine or a SARS-CoV-2 infection,” NCAI chair Dr. Shelley Deeks said.
“While we have seen that COVID-19 can peak at any time of year, we typically have a very strained health system during the respiratory virus season, which typically occurs during the fall and winter months,” she added.
“Offering another dose of COVID-19 vaccine starting this fall is expected to increase protection and will be particularly important for those at increased risk of COVID-19 infection or severe disease. This will benefit individuals and also may help reduce the impact of COVID-19 on the health system.”
Dr. Theresa Tam, Canada’s chief public health officer, echoed those comments, saying boosters will help prevent some of the stress on Canada’s health-care system.
“An additional dose using the latest vaccine formulations will be an important tool to not only build back protection against severe disease that wanes over time, but also protect against currently circulating SARS-CoV-2 variants,” Tam said in NACI’s report Tuesday. “This additional dose is especially important for those at increased risk of COVID-19 infection or severe disease.”
