I think the metrics are what they are. When you're looking for specific numbers, it's actually really difficult to do that, because you have to take into account all those metrics at the same time. They include what I've talked about, which is vaccine effectiveness, of course. The current two-dose vaccine regimen is not enough, so as chief medical officers we said that up-to-date vaccinations are what we recommend.
The other metrics, if you're looking at this, will be the pandemic activity across the world. In the United States it's still going up. In Canada the current wave has come down. That's great, but hospitalization is still high, and it depends on where you are.
I believe that kind of information has been provided to this committee, but we can certainly follow up.
