I think that depends on how our infectious diseases and other diseases emerge. As you've mentioned, we now have an HPV vaccine for cervical cancer. That's only the start of the investigations into vaccines for other types of cancers, and that's being actively pursued. We have a new vaccine that has come on the market for Rotavirus, an infection that really produces severe problems in very young children, and in fact through dehydration can often kill them.
So as we move forward, I think we're going to see more and more vaccines as a prevention measure. Again, one of the issues about the vaccinations is that this is another example of how we can't just have one province spending money on vaccines and vaccinating their population and the province next door not doing it. It's infectious disease, and we have to have a herd immunity in the entire population in Canada.
