Thank you, Mr. Chair.
I want to thank the witnesses for being available and for sharing their knowledge. It's very informative, and I appreciate it.
My question concerns an important factor for the future, which is the immunization acquired after contracting and beating the disease. To date, approximately one million people worldwide have recovered from COVID-19, including over 21,000 people in Canada. I don't think that we have any data to date that would lead us to believe that people have contracted the disease a second time.
My question is for Dr. Möröy and Dr. Gerdts.
How long must we wait before we have a good idea of the level of immunity acquired after fighting the virus? On that note, could more concrete tests be carried out on people who have recovered to ensure a faster verification of this factor? For example, can they return to a high-risk environment or can we “test” them in a laboratory by exposing them to the virus?
