Bipartisan Outcry Erupts Over Kennedy’s Vaccine Policy Overhaul

Health and Human Services Secretary Robert F. Kennedy Jr. faces increasing scrutiny and calls for resignation from both Democratic and Republican lawmakers following a contentious Senate hearing on September 4, 2025. During the session, Kennedy was questioned about his sweeping changes to public health policies, including the restructuring of vaccine guidelines and the removal of top officials at the Centers for Disease Control and Prevention (CDC). His actions have drawn bipartisan criticism, with family members such as former Congressman Joseph P. Kennedy III and his aunt Kerry Kennedy publicly condemning his leadership. Joseph P. Kennedy III described RFK Jr. as “a threat to the health and wellbeing of every American,” emphasizing the potential harm his policies could inflict on public health [1].

Kennedy’s tenure as HHS Secretary has been marked by significant and controversial decisions, including the replacement of the entire 17-member Advisory Committee on Immunization Practices (ACIP) with individuals who hold views skeptical of vaccine efficacy. This has raised concerns among medical professionals and public health officials, who argue that the changes undermine scientific integrity and public trust. The recent removal of CDC Director Susan Monarez, who was in her first month of leadership, further intensified the controversy. Monarez reportedly refused to comply with Kennedy’s demands to preapprove vaccine recommendations and fire senior CDC scientists. In response, Kennedy claimed that Monarez had been untrustworthy and was fired for refusing to align with his agenda [3].

The hearing exposed deep divisions within Congress and highlighted the political and scientific tensions surrounding Kennedy’s leadership. Senators from both parties expressed concerns over the potential erosion of long-established vaccine programs and the risks associated with altering public health policies based on non-scientific reasoning. Republican physician and Senator Bill Cassidy, who had supported Kennedy’s confirmation, criticized his decisions as a departure from the scientific standards he had promised to uphold during his confirmation process. Democratic senators, including Ron Wyden and Elizabeth Warren, accused Kennedy of endangering public health by restricting access to vaccines and politicizing public health recommendations [4].

Kennedy, however, defended his actions, asserting that previous leadership at the CDC and FDA was based on flawed data and lacked scientific rigor. He claimed his changes were necessary to restore the agencies’ credibility and ensure they operate under “gold standard” public health principles. Despite these justifications, many senators were unconvinced, with several reiterating their calls for his resignation. The health secretary also faced criticism for making unfounded claims about the safety of vaccines and for downplaying the effectiveness of the FDA’s Operation Warp Speed initiative, which played a key role in the rapid development and distribution of the COVID-19 vaccine [3].

The controversy has also drawn public backlash from former CDC officials and health professionals, who have raised alarms about the potential long-term effects of the policy changes. More than 1,000 current and former HHS employees signed a letter urging Kennedy to step down, citing concerns over the erosion of trust in public health institutions. Critics argue that the recent actions taken under Kennedy’s leadership could lead to a resurgence of preventable diseases and a decline in public confidence in medical science [5].

President Donald Trump, despite the growing criticism, has defended Kennedy, stating that his health secretary “means very well” and has “a different take” on vaccines. Trump praised Kennedy’s efforts to “make America healthy again” and reiterated his support for the HHS Secretary, even as lawmakers from both parties continue to question his leadership and policies [5].
