That's fantastic. That's incredible. Fantastic job, Sunnybrook.
I had a question about the start-up times you talked about. I wanted to talk a bit about the use of convalescent serum. As you probably know, this is old technology. I think there were some studies, both with H1N1 and Ebola, suggesting that it might be helpful, but they weren't randomized controlled trials. There is some evidence or “studies” from China suggesting it's effective, again with no randomized controlled trials.
Now Canada has set up the Concord trial—I think Sunnybrook is part of that trial—but the newspaper article yesterday noted that they drew their first batch of convalescent serum yesterday to start this up. I would take it from that you have not yet been using convalescent serum. Why has it taken so long?
Four days ago, I read an article in the Milwaukee Journal Sentinel talking about 2,600 people in the United States having used convalescent serum and, at least anecdotally, it was showing pretty good results. Why is it taking us so long to get this trial up and running?
