Thank you, Chair, and thank you again to everybody.
We've heard a lot from you about data collection and the challenges. We've heard from other witnesses about the challenges of data collection, including maybe the lack of provision of that data and oftentimes the imperfect data that epidemiologists and scientists have to make their decisions on. I'm glad to hear from you that there is at least some effort there and that people are trying to communicate that.
I saw today that VIDO-InterVac, out of the University of Saskatchewan, just announced on their study of testing a vaccine on ferrets that they're finding some positive results, in order, hopefully, as they go through those steps, to step forward into human testing.
Just recently, Health Canada approved the first serological test on the use of detected antibodies in those who had contracted or may have contracted COVID-19. Do you know how many immunity tests may have been performed on front-line health care workers in Canada? I'm just wondering if any of the researchers would know that.
