Thank you.
Ms. Combs, do you have anything to add? I know Mr. Genuis asked you a lot about AstraZeneca and the thrombocytopenia issue. As I said before, one can argue, as you say, the risk-benefit aspect. Basically, I think you've said the benefit outweighed the risk, but are you having problems other than people being afraid to take this particular vaccine in some countries? Do you see any other ways?
For instance, I wanted to hear some of you talk about the ability to train people to deliver vaccines, to put the needle in the arm. You don't have to be a physician or nurse to do that. Many people can be trained to do that.
How do you see this moving forward? As variants change regularly, some of us are going to find that these vaccines aren't going to work. What is your answer to that?
