“Make America Healthy Again” is a great idea — somebody should try it.

A lot of the concerns animating the MAHA movement — chronic disease, the unhealthiness of the American diet, how profits warp our health care system — are serious issues. But Robert F. Kennedy Jr. hasn’t taken major actions to address them. Instead he’s gutted funding for scientific research, including nearly $500 million dedicated to mRNA vaccine development, throwing a huge amount of possibly lifesaving research in limbo.

How did we get here? What are the politics that allowed Donald Trump to preside over Operation Warp Speed, the single most successful pandemic mitigation policy, and then turn around a few years later to appoint Kennedy to undo it all?

My colleague David Wallace-Wells has done incredible reporting on how pandemic policies have shaped our politics, culture and society. Rachael Bedard is a physician and a writer who has been thinking deeply about what MAHA represents and where the movement could find common ground with its critics.
