On global statistics, the WHO itself has a database that tracks some of this. How accurate and up to date it is is always a question.
However, on your point about whether we can do something interactively—Mark might be able to shed some light on it—there's no reason that we couldn't be more creative. I think back to the agreement some days ago between Manitoba, I think it was, and a state south of it, in which truckers going south could be vaccinated in the U.S.
There's lots of room for this kind of creativity at the national level. The U.S. said that they hadn't approved AstraZeneca and had one and a half million doses and that many of them would go to Canada, and there's no reason we shouldn't be doing that.
That tells me something else, which is that vaccine distribution has become part and parcel of foreign policy and foreign relations, which is still one step removed from improving global welfare. I'd remind us that the very scary variant that we're now hearing about from India, and previous to that from the U.K., South Africa and Brazil, all come from regions where the vaccine was not being deployed as much as it should have been. As much as it would be great to have the U.S. and Canada exchange vaccines, that's doing nothing for the medium-term problem, which is that 130 countries have yet to deliver a dose. That's where the mutants are going to be originating.
