At a hybrid event presented live and via webinar on May 30, 2023, OHS Scientific Associate Dr. Victoria Kirsh provided an update on CanPath’s national COVID-19 Antibody Study.

Using real-world data from the SUrveying Prospective Population cOhorts for COVID-19 pRevalence and ouTcomes in Canada (SUPPORT-Canada) study which included questionnaire and blood spot sample contributions from nearly 10,000 OHS participants, Dr. Kirsh examined the effectiveness of COVID-19 vaccines and the relative protection afforded by them compared to prior infection. Over 2 million lines of code were analyzed for the study leading to several surprising findings. Read a summary of Antibody Study Questionnaires here.
