VELSHI: Thank you, Alexis, and thank you for everybody who's joining today. Please participate and ask questions because we've got a panel here of experts who've really thought about this and have answers to some of the things that concern us about the global application of the vaccine and the way it's being distributed. As you know, I won't repeat it because it's in the schedule and you have signed up for it, but we are essentially talking about vaccine nationalism here and distribution of vaccines. What is fair, what is just, what is right? Also, what is effective, what is necessary? Something that may not be fair may be important, and something that may be unfair is necessary. So let's talk about some of those things with this fantastic panel.
