I'll respond first to the question and then I'll pass it on to Dr. Butler-Jones.
I have said all along that the chief medical officers across the country have been looking at all of the cases we have seen in Canada, particularly the severe cases, which in some cases have resulted in death, to study and examine the underlying conditions those individuals may have had that resulted in death, and they are looking at the population, and so on. Next week, on Wednesday, the chief medical officers are gathering to further examine what other factors there may be and who is more affected.
But what I have outlined today is what we have seen, particularly in the higher-risk and serious cases--with pregnant women, as an example--and the younger population being hit by H1N1 across the country, aboriginal or not. This is the kind of information being collected that will help shape the guidelines we will be prepared to implement in the fall, as well as the sequencing of how the vaccine will be implemented.
Perhaps, Dr. Butler-Jones, you may want to elaborate a bit more on that.
