I can summarize quickly that we have learned a great deal about some of the intricacies of shipping at scale hundreds of packages across the country of a vaccine that is highly sought after. We have seen some discrepancies in tracking numbers and addresses, so errors that are easily fixable, and we have addressed those with the provinces and territories.
We've also identified some risks associated with shipping packages in remote and isolated areas as well as into the north in the winter with the complexities that distribution can present in terms of air travel, road travel as well as over-the-water travel. There's a number of small lessons that have been captured and are being addressed in distribution, particularly as we scale up in the month of April and onward.
