It’s pretty easy when you have vaccines that are 95% effective. Can’t get much better than that. I think what people need to appreciate — and that’s why I have said it like maybe 100 times in the last week or two — is the process by which a decision is made. The company looks at the data.

The FDA commissioner has vowed publicly that he will go according to the opinion of the career scientists and the advisory board.
