10,000 Canadians to be tested for COVID-19 antibodies in hopes of understanding immunity coronavirus
Dr. Prabhat Jha demonstrates how to use the home kit that will be sent to participants in the study. TORONTO -- After a person has developed antibodies against COVID-19, how long does that immunity last?
Those who get officially tested for COVID-19 are generally those who are showing clear symptoms. Because of this, the current testing alone doesn’t provide the full picture of the virus’s spread in Canada, Jha said. The kit itself is simple. It comes with a lancet to draw blood, gauze, an alcohol wipe, a bandage, an information sheet, an instruction manual and a consent form.
“It's a simple process that actually has been used in developing countries for quite a while, because doing blood-based studies [there] is really difficult,” Jha said. “So people have moved to this technology and interestingly, we're bringing it home to Canada.” Participants will be able to see their results if they choose, but Jha cautioned that “these aren’t immunity passports.”
“And also are there new infections in people who weren't infected before? So that gives you some sense of ongoing transmission. Then finally we'll be able to say, well, by linking to the health records of testing, if someone had antibodies, did it protect them against getting infected in the followup period?WHAT RESEARCHERS HOPE TO FIND OUT
