In an unprecedented and highly consequential development, a group of nine former leaders of the Centers for Disease Control and Prevention (CDC) has publicly and formally accused Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. of endangering the health of the American people.1 In a scathing guest essay published in The New York Times on September 1, 2025, the former officials—spanning both Democratic and Republican administrations dating back to the Carter era—warned that Kennedy’s actions were “unacceptable” and “unlike anything our country has ever experienced.”2 This rare and unified rebuke from the nation’s top public health experts serves as a powerful condemnation of what they view as a systematic dismantling of the country’s health infrastructure.
The core of the former leaders’ condemnation revolves around Kennedy’s long-standing and well-documented skepticism toward vaccines and his recent actions as HHS Secretary.3 They pointed to his abrupt dismissal of CDC Director Susan Monarez, who reportedly clashed with him over vaccine policy and refused to “rubber-stamp unscientific, reckless directives.”4 This firing triggered a wave of resignations from other senior CDC officials, leaving the agency in a state of chaos.5 The former leaders, including Drs. Rochelle P. Walensky, Mandy Cohen, and Tom Frieden, said they were deeply concerned that Kennedy was “focusing on unproven ‘treatments’ while downplaying vaccines” and canceling vital medical research.6 The group cited Kennedy’s cancellation of a $500 million federally-funded mRNA vaccine research program and his appointment of individuals with “dangerous and unscientific views” to key federal health advisory committees.7
The unified nature of the dissent is particularly striking. Coming from a bipartisan group of career professionals, the essay’s message transcends partisan politics. It frames the issue not as a clash of political ideologies but as a fundamental threat to the scientific integrity of public health institutions. The former leaders underscored this by stating that while they did not always agree with their respective leaders during their tenures, they “never gave us reason to doubt that they would rely on data-driven insights for our protection, or that they would support public health workers.” This statement implicitly contrasts their past experiences with what they describe as Kennedy’s ideological agenda, which they argue prioritizes political gain over evidence-based science.
The public health community has been sounding the alarm about Kennedy for months. Since his confirmation, his actions have been a source of constant concern. Just days before the former CDC leaders’ essay, senior CDC officials resigned in protest, with some accusing Kennedy of ignoring and sidelining experts.8 Dr. Demetre Daskalakis, a former CDC director for the National Center for Immunization and Respiratory Diseases, stated in his resignation letter that Kennedy had never been briefed by any of his center’s experts.9 This collective “cry for help” from inside the government, now joined by a chorus of former leaders from outside, signals a dire situation.
The repercussions of this crisis are immense. The former leaders warn that Kennedy’s actions put the U.S. at risk of a resurgence of vaccine-preventable diseases like measles and polio.10 They argue that by undermining the public’s confidence in science and dismantling key research programs, the administration is leaving the nation vulnerable to future pandemics. The essay serves as a powerful call to action, urging the public, Congress, and all who care about the nation’s health security to pay close attention. It is a stark reminder that public health is not a political football but a fragile system built on trust, expertise, and scientific rigor—a system, they argue, that is now in grave danger.
