Health Secretary RFK Jr. has gutted the CDC's vaccine advisory committee, replacing its members with a mix of anti-vaxxers, COVID contrarians, and medical non-professionals. What do these sweeping changes to our vaccine infrastructure—and the rise of the ironically named MAHA movement, short for Make America Healthy Again—mean for the health and well-being of everyday Americans? Dan sits down with epidemiologist and data scientist Katelyn Jetelina to unpack the implications of Kennedy's policies on flu season, COVID, and a broad range of preventable diseases. Katelyn also explains how the politicization of seed oils, food dyes, and fluoride distracts from the public health issues that actually matter—and shares what she learned from grassroots MAHA organizers about their uneasy alliance with MAGA.
