I'd also like to follow up on what you both have said about capacity and building up health systems. I've noted that in addition to the $732 million extra for the ACT-Accelerator in the 2022 budget, we are also providing $296 million to build up health systems around the world.
I'll start with Ms. Caprani.
Can you tell us why this is so important, particularly when you're talking about children and talking about future pandemics? Why is it so important that we're funding not just vaccines but health systems?
