Immunogenicity of current SARS-CoV-2 vaccine schedules currently used in Canada

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 this 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.

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.
