The New Yorker contributing writer Dhruv Khullar joins Tyler Foggatt to discuss how Donald Trump is transforming the nation’s approach to vaccines and immunization during his second term. They talk about the repopulating of federal agencies and advisory panels with skeptics, the politicization of once technical debates under the “Make America Healthy Again” agenda, and what happens when people distrustful of the medical establishment end up running American public-health policy. They also examine how states are stepping in to fill the vacuum left by Washington, creating a patchwork of approaches to vaccines across the country.
