Secretary of Health and Human Services Robert F. Kennedy, Jr.'s agenda, he says, is chronic disease prevention. He wants Americans to eat fewer ultra-processed foods; to decline long-established childhood vaccines against diseases like the measles, which we never see anymore; and to drink public water supplies without fluoride, apparently as a boon to the dental profession. HHS recently announced that it will spend $10-20 million on a "Take Back Your Health Campaign" that is intended to "alert Americans to the role of processed foods in fueling the diabetes epidemic and other chronic diseases, inspire people to take personal responsibility for their diets, and drive measurable improvements in diabetes prevention and national health outcomes."
Diabetes is a big problem. I'm all for preventing diabetes through healthier eating. But the longest-running longitudinal study of diabetes prevention, the Diabetes Prevention Program Outcomes study, was terminated in March when the Trump administration froze hundreds of millions of dollars in federal health grants to Columbia University, where the study coordinating center is located:
The lapse in funding means that the Diabetes Prevention Program Outcomes Study can no longer continue to collect patient data as planned; it can no longer pay staff to do blood work, collect urine samples, scan brains, or conduct neurocognitive tests. Even worse, the study’s existing data are at risk. Scientists need funds to properly store and retrieve samples; they need money to pay for computer servers and to hire statisticians and analysts, who clean and curate the data.
HHS has traditionally relied on panels of non-government experts to guide its work in prevention, and after the DOGE-driven cuts that resulted in the departure of 20 percent of its workforce, it needs outside help more than ever. For decades, five independent scientific advisory panels made evidence-based recommendations on clinical preventive services, community preventive services, newborn screening tests, infection prevention, and immunizations. Two of these panels have already been dissolved, and the remaining three are on life support.
I wrote a Medscape commentary about current threats to the U.S. Preventive Services Task Force (USPSTF), which include the hobbling and proposed elimination of its convening agency (AHRQ) and a lawsuit that the Supreme Court should decide any day now. The USPSTF's sister panel, the Community Preventive Services Task Force, which "evaluates evidence and recommends effective interventions to improve health in the community, home, school, work, and health care settings," hasn't been convened at all this year.
Each year, newborn screening identifies about 14,000 infants with serious conditions that benefit from early intervention. Early detection can prevent death or irreversible harm in disorders like metabolic diseases, immune deficiencies, and muscular atrophies. Eliminating the ACHDNC creates a dangerous vacuum in the nation’s newborn screening system, stalling progress on adding life-saving tests to the RUSP and increasing the risk that diagnoses will be delayed or missed for some babies—with potentially tragic results.
Without transparent, evidence-based processes, vaccines may become inaccessible, unaffordable, or unavailable. Public trust will erode, innovation will stall, and lives will be lost unnecessarily. The systematic unraveling of our vaccine infrastructure endangers our freedom to protect ourselves and our communities. We urge congressional leaders to reflect on how these fragmented decisions collectively dismantle our ability to prevent disease and save lives.
