Thank you very much.
Thanks to all the panellists.
Dr. Warshawsky, first of all, having been in the game for a while, I want to recognize the incredible work that you and other members of NACI have been performing during the last two years, often under incredible pressure. I wonder if, sort of at a high level and as briefly as possible, you could comment on some of the challenges associated with translating data during a pandemic into policy and vaccine recommendations.
