OTTAWA—Blood samples collected from tens of thousands of Canadians will soon be tested for signs of COVID-19 antibodies as the federal government seeks to learn how many people have already contracted the novel coronavirus.
Dr. Theresa Tam, Canada’s chief public health officer, said she is excited about the partnership between the national immunity task force and Canada’s blood agencies, Canadian Blood Services and Hema-Quebec. Tam is a member of the task force.
