Thank you, Madam Chair. I have a couple of comments.
When the contracts were put in place with the seven different manufacturers, again, this was during last summer, at a time when nobody was certain which vaccines would actually make it across the line. We have two that have made it through regulatory approval and, hopefully, more to come soon. That was the reason, and companies were taking risks to basically do research, clinical trials and start production at the same time, so there was a need to sort of pony up if you wanted your foot in the door early.
In terms of what happens if they all come to fruition and Canada gets more doses than we need, well, there's an ability to donate. As has already been mentioned, no one is really sure what the durability of these vaccines is. Is this an annual thing so that they could be folded into future years' vaccines as well? There's flexibility there, and I think, frankly, that it's just too early to say what will happen, given the various stages of regulatory approval.
