 So, Andrew, tell me what exactly does this fund do? What's it been doing? Well, so PEPFAR has really been the backbone of not just the US's response to HIV, but really the global response to HIV. I mean, the program has saved more than 25 million lives since it was launched two decades ago. And that's by spending money on both treatment and prevention programs, especially for groups of people who are often overlooked in the global response.
