COVID-19 testing of health professional students, residents, and Faculty of Health Sciences graduate students: Informing testing and public policy for universities and society

Anne Ellis, Queen’s University

This study looks at the antibody levels of students from the Faculty of Health Sciences at Queen’s University who train and work at the Kingston Health Sciences Centre. Researchers will focus on students who have no symptoms to determine the prevalence of asymptomatic SARS-CoV-2 infection among this group.

Immunogenicity of current SARS-CoV-2 vaccine schedules in BC and Ontario

Pascal Lavoie, University of British Columbia

This study is looking at the level of protection people have after a first dose of the COVID-19 vaccine and after a second dose with an extended dosing schedule. Researchers are also determining why some people do not develop adequate protection (non-responders) even when receiving vaccines on a recommended schedule.

REinfection in COVID19 Estimation of Risk (RECOVER)_Phase 2/Vaccine

Caroline Quach-Thanh, Centre hospitalier universitaire Sainte-Justine

The phase 3 clinical trials of the Pfizer-BioNTech and Moderna vaccines did not include participants with prior SARS-CoV-2 laboratory-confirmed infections. Using a cohort of healthcare workers, this study aims to understand how people who have had a SARS-CoV-2 infection respond to COVID-19 vaccines over 18 months.

The Canadian COVID-19 Cohort Study for people working in hospitals (Are healthcare workers at higher risk of COVID-19 than other working adults? )

Brenda Coleman and Allison McGeer, Sinai Health System

The Canadian COVID-19 Cohort Study (CCCS) follows 2,000 health care workers from Halifax, Sherbrooke, Ottawa, Toronto, Hamilton, Calgary, and Edmonton. The study will identify occupational risks, determine the incidence of SARS-CoV-2 infection, study the uptake and effectiveness of vaccines and, assess the psychological impact of working in a hospital during a pandemic.

The impact of COVID-19 on the health of physicians, nurses, and other health care workers

Nicola Cherry, University of Alberta

The study follows more than 5,200 health care workers in British Columbia, Alberta, Ontario, and Quebec in order to determine how many have antibodies to SARS-CoV-2 and identify workplace practices that could be improved and made safer. They will also assess the state of their mental health and identify workplace practices as well as family/community supports that could alleviate stress.
