Thanks for the question.
If we're trying to build a situation of preparedness, obviously vaccines are a key and core part of that, particularly for illnesses of pandemic potential. When we currently are licensing very safe vaccines in Canada—which we know we do—the part that we often forget about is that we have great vaccines, but we can always expect to raise the bar and make them better. One way to do that is to have the people involved in the manufacture and dissemination of our vaccines to provide us with studies of immunity and effectiveness in real time—and real immunity. That's really important for us in order to go forward in building a real science base that adds trust in vaccines—ups the ante not just to 80%, but to 90% and 100% effective—and in understanding what people need at an individual level. We can do that, potentially through a regulatory way, especially if we demand in our pandemic preparedness and prevention plan that vaccines be maximally effective, licensed and subsequently modified as we go along, so there's rapid access, but high standards for modification afterwards.
