Psychedelics and immortality: Nature went to a health summit starring RFK and JD Vance

US health policy is shaped by the priorities highlighted at the Make America Healthy Again summit, which Nature attended. The gathering drew attention because US health secretary Robert F. Kennedy Jr and vice-president JD Vance were present, and the event offered insight into what motivates current policy directions. The summit also connected psychedelic ideas with larger themes of ageing and “immortality”, illustrating how hype, science messaging, and politics can converge in mainstream health debates.
