 If you look ahead across 2021, what do you think the key themes and trends will be this year? Equitable access to the vaccines, I think, is one decision point in 2021 that we must get right. There is growing tension about equitable access to the vaccines. We must make sure we keep going with the science that lies behind that, that we make sure we invest in those second generation vaccines. I do start 2021 really optimistic about the progress that was made in 2020 and the willingness of the world to come together, including in things like the ACT Accelerator and with the World Health Organization, to say we will not defeat this pandemic until we defeat it everywhere. And I actually feel very optimistic that that will be the course that humanity chooses.
