The Angus Reid Forum has partnered with the University of Toronto and St. Michael’s Hospital in a ground-breaking study of COVID exposure and antibody resistance in the Canadian population. Over the course of the last year, ARF has polled a random sample of more than 10 000 Canadian adults to collect information on potential exposure to COVID-19 as well as other vital public health information. Thousands of those survey participants have also volunteered to send in dried blood samples, which will help the Ab-C research team, and Canadian policymakers in turn, better understand the impact and spread of the COVID pandemic.
