Thank you very much for the question. I'll take a crack. Then if Steve wants to come in, that's fine.
Just to go back to the road map and the discussions last week, I think what you see is a pretty comprehensive engagement on all things COVID. That includes ministers and officials from a slew of departments, whether on the health side or the border side, just really ramping up their engagement.
When it comes to vaccines, to my understanding we have an agreement with a company for the provision of 20 million doses of vaccines from the United States. As it stands, we're looking forward to those deliveries. We have not seen anything to indicate that there would be any disruption to that.
Steve, do you want to come in?
