Certainly, what was not anticipated, even a few weeks ago, was the level of interest. Nobody really anticipated it. There's lots of experience with vaccination clinics but we did not expect the kinds of willingness to line up, etc., that was experienced. The provinces and territories have been planning for this for a long time. They were surprised by the level of interest, particularly when only a few weeks ago people were saying we'd be lucky to get a third of the population willing to be immunized at all. That's the first reality.
In terms of the single-source contract, that is a contract that was put in place to ensure access and total amount of vaccine--it was domestic production--for all Canadians. That actually has served us well. Countries with multiple contracts are not as well off as we are with the single-source contract.
That having been said, as we review all of what we go through, and when we look back at this and plan for the next pandemic, one of the things we'll clearly be looking at is having a second smaller supplier. Again, there's a security issue because it's not produced in Canada, but at least having that as a possible option will be one of things we'll be looking at.
