Nearly a quarter (23.6%) of a sample of South Asians living primarily in Ontario’s Peel Region1 had evidence of prior infection with SARS-CoV-2 by the end of the pandemic’s third wave in July 2021, according to a CITF-funded study published in the Canadian Medical Association Journal (CMAJ) Open.
Among people who were pregnant in Ontario in March 2022, 81.3% had received one or more doses before or during pregnancy.
SARS-CoV-2 infection during pregnancy associated with increased risk of adverse maternal and perinatal outcomes
CITF-funded researcher Dr. Deborah Money, from the University of British Columbia, and the CANCOVID-Preg team published a study in JAMA, observing that SARS-CoV-2 infection during pregnancy was significantly associated with an increased risk of adverse maternal outcomes and preterm births in those who were unvaccinated.

Canadian study shows no significant association between COVID-19 vaccination and adverse peripartum outcomes
In a paper published in JAMA (Journal of the American Medical Association), CITF-funded researchers Drs. Deshayne Fell and Kumanan Wilson of the University of Ottawa and Dr. Jeffrey Kwong from the University of Toronto and colleagues found that COVID-19 vaccination was not significantly associated with an increased risk of adverse pregnancy outcomes.
A pre-print, not yet peer-reviewed, from the CANVAS Network, by Drs. Julie Bettinger and Manish Sadarangani from the University of British Columbia and their colleagues explored the safety of COVID-19 vaccines in pregnancy among 15-49-year-olds and compared them to an unvaccinated control group, including unvaccinated pregnant people.
Non-peer-reviewed data from the CITF-funded COVENANT Study, exploring the impact of SARS-CoV-2 among populations experiencing homelessness in Toronto, found the majority of participants (80%) reported being vaccinated by September 2021, with 79% of them having two doses. 14% were hesitant to be vaccinated. The results were given by study lead Dr. Stephen Hwang, from [...]
Congregate settings (such as prisons, long-term care homes) have provided opportunities for COVID-19 to flourish. As part of her CITF-funded work, Dr. Nadine Kronfli from the Research Institute of the McGill University Health Centre studied a cohort of incarcerated men at three provincial prisons in Quebec.
In their third report, CITF-funded researcher Dr. Deshayne Fell and her team at the Better Outcomes Registry & Network (BORN) in Ontario found that 58.7% of people who were pregnant in September 2021 had received at least one dose of a COVID-19 vaccine before or during pregnancy. Since pregnant individuals are considered a high-risk population for COVID-19 complications based [...]
Congregate settings (such as prisons, long-term care homes) have provided opportunities for COVID-19 to flourish. As part of her CITF-funded work recently released in a Lancet preprint, therefore not yet peer reviewed, Dr. Nadine Kronfli from the Research Institute of the McGill University Health Centre found that the number of incarcerated men at three provincial prisons in Quebec with antibodies due to a SARS-CoV-2 infection was two times higher than among nonvaccinated individuals in the Montreal area.
