Yes, I'm always trying to be optimistic. As I've said, every pandemic ends, and we now have many more tools available to us, including a lot more knowledge on vaccines.
We have so much innovation in the field. This will be one of the most studied viruses, I think, and the treatments are coming out and the tests and a lot of collective learning on this very virus, so I think with that I am definitely remaining very optimistic about the months ahead.
