Okay.
In my next question, I want to rationalize two different parts of this. I think I may know the answer, but I want to make sure that I do. Both Dr. Sher and Health Canada have repeated several times that there is no 100%-safe test for pathogens.
You've talked about the window of between nine days and two months whereby a pathogen could get into the blood supply. You've said that safety is paramount and that it's based on the science. You look for potential risks and put in whatever protections are needed.
Also, Dr. Sher, I wrote down your words that you “expect donors to be honest”.
My question is about Health Canada's policy with respect to allowing paid plasma donors. The theory is that if you're paying donors to give plasma and you're appealing to vulnerable populations—poor people, drug users—you're creating an incentive for them to come. If they need money for the donation, the theory—and the worry—is that if you ask them about their behaviour, they have a financial incentive to be less than honest. I've been told and led to believe that there is no issue there with respect to plasma, yet....
I'm trying to square these two things. Are the tests 100%? Are donors' questions important or not? Or is it the difference between the way the plasma and the blood supply, whole blood, is stored and tested that makes these two different issues?
