What will it take to better prepare the world for the next pandemic, and why are vaccine equity and disease surveillance critical to that effort? In this episode of the Infectious IDeas podcast, NFID CEO Rebecca Alvania, PhD, MA, MPH, and NFID Medical Director Robert H. Hopkins, Jr., MD, have a candid conversation with Richard J. Hatchett, MD, CEO of the Coalition for Epidemic Preparedness Innovations (CEPI) and recipient of the 2026 NFID Jimmy and Rosalynn Carter Humanitarian Award. He shares his thoughts on the 100 Days Mission, the lessons of Ebola epidemic, and why he sees pandemic preparedness as a matter of conscience as much as science. Hatchett traces an unlikely path from a medical residency during the early years of the AIDS epidemic, to Ebola fieldwork in Gabon, to volunteering at Ground Zero after September 11 — the same instinct, he says, that later led him to help found CEPI in response to the West African Ebola epidemic. He discusses the current Bundibugyo virus outbreak in the Democratic Republic of the Congo and Uganda, the chronic underfunding of disease surveillance, and why he considers CEPI's commitment to equitable vaccine access more significant than any of his own technical contributions.

Transcript Alvania: Welcome to the NFID podcast, Infectious IDeas. This is Rebecca Alvania, NFID CEO, and with me is my co-host, NFID Medical Director, Dr. Bob Hopkins. Hopkins: Hey, happy to be here, Rebecca. Alvania: Our guest today is Dr. Jeremy Farrar. He serves as the World Health Organization's Assistant Director-General of health promotion and disease prevention and control. Many of you know him for his groundbreaking work on infectious diseases with pandemic potential. He's also held major leadership roles, including director of the Welcome Trust and co-founder of Coalition for Epidemic Preparedness Innovations (CEPI), the global effort to speed vaccine development and ensure access worldwide. In 2019, NFID honored him with the Jimmy and Rosalynn Carter Humanitarian Award. It recognized his impact on global public health and his commitment to making the world a more equitable place. Jeremy, thank you so much for joining us. Farrar: Great pleasure. Alvania: All right, we're going to start at the beginning. You began your career working in HIV AIDS. How did those early experiences shape you as a scientist? Farrar: That would have been in the late 1980s and of course, that was the time that HIV was becoming known about. And I do remember—I was a medical student, and soon after graduating—just the impact this had. I was working in London at the time, and medical students and doctors had got used to the idea that many things were treatable, and then suddenly you had mostly young individuals coming in. And frankly, there was very little anybody could do. Obviously, we didn't know what the cause was, and that was devastating, actually. But also on the positive side, as a result of great science and great public health, some solutions did start to come, and I pay huge tribute to the community who were then known to be living with HIV, because the role they played in pushing science and pushing public health was, I think, absolutely groundbreaking. And I'm not sure the establishment would have got there quite the way it did without that pressure from the community. So, three lessons: one, is the devastating impact of something new, in this case, HIV. Secondly, the incredible power of science. And thirdly, the critical importance of communities being part of engaging and owning the solutions. Alvania: What led you to global public health after that experience? Farrar: Th Follow NFID on social media
