Thank you, Mr. Chair.
I'd like to start by thanking Dr. Langley, Mr. Lievonen and Mr. Scott-Douglas for joining our committee meeting today and for their incredible service to our country by volunteering to be part of this critically important vaccine task force. We really appreciate the work you've been doing over the course of the last year plus, and going forward.
Dr. Langley, what are the factors that the vaccine task force utilized to help the government decide on which vaccine suppliers to pursue?
