As I've mentioned, Canada is playing a big role right now around vaccines. This can always be increased. Obviously, this problem is as complex as we see in Canada. You can only imagine that as we get into it, and the vaccines start to flow, especially to the developing world, we're going to run into barriers very similar to those in Canada.
Investment requirements will change, and we'll have to be very agile and flexible in terms of our approaches. As someone just mentioned, the number of vaccines, and how you store them, how you transport them, how you deliver them, the amount of doses, all those things are constantly moving targets.
We don't have all the answers right now. Even the price of vaccines is a constantly changing landscape. What we do know is that we are starting to look at what it will actually take to deliver the vaccines effectively. That does not count in terms of the actual purchase of vaccines, but just to get them into the arms of people, because having vaccines is critical.
As you mentioned, people who are in conflict settings or in displaced camps....That will be a much bigger cost. Canada has a huge role to play.
