In general, it's really the jurisdictions that prioritize how vaccines are given in their particular communities and to whom they give the vaccines. Some jurisdictions, even with seasonal flu, give the vaccine to selected groups as opposed to the whole population, as is the case in Ontario and certain other selected jurisdictions where they have universal flu programs.
We would only develop a priority list for influenza vaccine in the case that there was a flu vaccine shortage. From the standpoint of a jurisdiction, it would probably be at the jurisdictional level, based on their issue. It does raise an interesting question about when we've had other vaccine shortages, not flu vaccines but other vaccine shortages. The jurisdictions have to work together, which they do, to identify how we're going to adjust to that shortage. Sometimes it can mean that we're looking for vaccine from another supplier. I have to admit, from that standpoint, there's always work to be done. That's another issue that has been identified as we think about our national immunization program: How do we plan and mitigate against vaccine shortages and adjust and work together to address them when they occur?
From a pandemic standpoint, we have a framework. We're not going to address a prioritization framework for the next pandemic until it occurs.
