Vital Margins

Vital Margins is a podcast about the hidden forces shaping medical donation. Host Vikram Varanasi, founder of the HopeLink Initiative, explores how biology, economics, and human behavior intersect, and why gaps in medicine aren’t just about science, but about systems, incentives, and who gets left out.  Each season focuses on a different corner of that world. Season 1 examines stem cell donation: the science of HLA matching, the behavioral economics of donor registries, the researchers pushing the field forward, and the grassroots organizations making sure the most underrepresented communities aren’t left behind. Each episode features conversations with researchers, clinicians, and advocates who are working at the edge of what medicine and policy can do together.
