On September 17, Drs. Susan Monarez and Debra Houry testified before the Senate Committee on Health, Education, Labor, and Pensions (HELP) in a critical hearing addressing leadership challenges at the Centers for Disease Control and Prevention (CDC) and the implications for vaccination policies affecting children’s health. Dr. Monarez was sworn in as the first-ever Senate-confirmed CDC Director on July 31 of this year, yet was abruptly fired by the administration not even a month into her tenure after refusing to comply with directives from Robert F. Kennedy Jr., Secretary of the Department of Health and Human Services (HHS). Dr. Houry, former Chief Medical Officer and Deputy Director for Program and Science at the CDC, recently resigned in protest of threats to the foundations of scientific integrity at the CDC.
Opening Remarks
Senator Bill Cassidy, MD (R-LA), Chair of the HELP Committee, opened the hearing, focusing on President Trump’s mission of restoring “radical transparency” at the CDC. He emphasized his duty to the administration to uncover the truth about the sudden firing of Monarez and to help Trump build the strongest CDC in the nation’s history. Cassidy ended his remarks by underscoring the importance of his own goals to protect children’s health, rebuild trust in institutions, and Make America Healthy Again (MAHA).
In his opening statement, HELP Committee Ranking Member Bernie Sanders (I-VT) highlighted the controversy of Kennedy’s rhetoric surrounding Monarez’s firing, as he labeled her a “liar” and “untrustworthy.” Sanders argued that Monarez was dismissed because she refused to become a rubber stamp for Kennedy’s agenda, which aims to substantially limit the use of safe and effective vaccines, potentially endangering lives globally. Sanders praised Monarez for standing up for science and public health.
Drs. Monarez and Houry Give Testimony
Monarez began her testimony with an assertion of her scientific credentials and claimed that official explanations for her firing are inaccurate, emphasizing that the hearing should focus on restoring public trust in health. She noted that concerns about the Advisory Committee on Immunization Practices (ACIP) began weeks before her dismissal and recalled the tragic event that occurred on August 8, when a gunman motivated by vaccine distrust fired 180 rounds into CDC headquarters, killing a police officer and rattling CDC staff and Americans. According to Monarez, Kennedy demanded that she pre-approve all ACIP recommendations regardless of the scientific evidence and dismiss career vaccine scientists without cause. Monarez concluded by expressing concern about the potentially severe consequences of inadequate vaccination for children and vulnerable populations, highlighting that although she could have retained her position by complying, she chose to preserve her integrity for future generations.
In Houry’s testimony, she stated that she served 10 years at the CDC, spanning six directors and four administrations, before resigning because CDC leadership had become “reduced to rubber stamps.” She argued that trust and transparency have already been broken, highlighted by Kennedy changing CDC vaccine guidance through a social media post without scientific justification, deviating from Gold Standard Science (GSS) practices. Houry stressed that these actions were contrary to the tenet of radical transparency touted by the Trump Administration.
Houry also closed with a warning about the preventable deaths from infectious disease that would occur if changes to the vaccine schedule are made without support from new scientific evidence or data. Chair Cassidy echoed these concerns during his closing remarks.
Rift in the Republican Party
While Drs. Monarez and Houry were praised by Democrats, Independent Bernie Sanders, and a few Republicans, several of the Republican Senators focused on their concerns regarding Monarez’s lawyer, Mark Zade—a staunch critic of President Trump—and her truthfulness about the events of her meeting with Kennedy. As such, it is unclear if the testimony will bring the Republican party closer to their goal of radical transparency.
