I will, only to add that certainly, as you've described, Michael, on the vaccine side there's work going on.
The issue that I'm more focused on and that some of our teams are more focused on is how we make sure we're in the same space as the U.S. when it comes to what we're both going to be doing on COVID recovery and the economic issues related to that—the whole issue of building back better, which also draws in the environmental and climate change issues that have been mentioned before. The integrated economy and resilient supply chains are the kinds of issues we're focusing on. Obviously, vaccines are a priority, but there's much more we're doing with the U.S. in relation to COVID and its implications.
