I understand the concern for sure, and it's very much looked at in detail in our projections, but by February 15 we'll have a significant increase in quantities and be moving forward in Pfizer shipments. We expect that provinces will be able to manage that and stick to the NACI recommendation for up to a 42-day interval and specific problems can be flagged by provinces and we can see how we can readjust.
It's a zero-sum game so we'll have to shift from one jurisdiction to another prior to arrival to ensure we don't find ourselves in a situation where we have an extended period without the second vaccine. The CMHOs and Dr. Tam's office federally are also looking at that, but really it's the provincial and territorial public health officers.
