Thank you very much.
I'd like to ask a question that hasn't come up yet.
We know that right now, certainly in the global south, testing and treatment are becoming vitally important. In terms of treatment, the antivirals—I'm looking at Paxlovid and some of the others—are becoming very important. I'm not a scientist, but there seems to be some anecdotal evidence that this could also be effective in terms of long COVID.
We're looking at a pandemic right now, but we know that the debilitating long-term effects of COVID are still not known and there will need to be treatments for that as well. Are you putting any money and research into antivirals and into long COVID? How do you see this as being something that could help in terms of the global south and where the pandemic is going next?
Could we have Pfizer first, please?
