Recent Appointments and Departures
On December 3, 2025, the U.S. Food and Drug Administration (FDA) appointed Tracy Beth Hoeg as the acting director of the Center for Drug Evaluation and Research (CDER). This appointment follows the sudden retirement of Richard Pazdur, who had only been in the role for a few weeks after succeeding George Tidmarsh, who resigned amid allegations of misconduct. Hoeg, a physician and epidemiologist, has been a controversial figure due to her skepticism regarding COVID-19 vaccines and her advocacy for changes in vaccination policies.
In a related move, Theresa Michele, the longtime director of the Office of Nonprescription Drugs, was reassigned to a leadership position in the FDA’s medical devices center. This transition reflects the agency's ongoing restructuring under U.S. Health Secretary Robert F. Kennedy Jr. Michele's tenure, which began in 2015, was marked by criticism regarding the pace of non-prescription drug approvals.
Implications of Leadership Changes
The FDA has experienced significant upheaval, with five changes in leadership at CDER this year alone. These shifts have raised concerns about the agency's stability and its ability to effectively manage drug evaluations and public health policies. FDA Commissioner Marty Makary has emphasized the need for modernization within CDER, stating that Hoeg is the right scientist to establish a culture of coordination across the agency.
The FDA's recent leadership changes coincide with a broader reevaluation of vaccine policies, particularly regarding childhood vaccinations. A panel is set to vote on whether to delay hepatitis B vaccinations for most American children, a decision that could represent a significant shift in public health strategy.
Criticism and Opposition
The changes at the FDA have drawn criticism from former commissioners across the political spectrum. A group of twelve former FDA commissioners expressed concerns that the new directives regarding vaccine policy could undermine the agency's credibility. They argue that the proposed changes are not merely adjustments but represent a fundamental shift in the FDA's approach to its regulatory responsibilities. The commissioners highlighted the lack of transparency in the decision-making process, particularly in light of claims linking COVID-19 vaccines to adverse outcomes.
Official Statements
Marty Makary, the FDA Commissioner, stated, “Dr. Hoeg is the right scientist to fully modernize CDER and finish the job of establishing a culture of cross-center coordination there.” He has also indicated that the agency is focusing on making drug approvals more efficient and affordable.
Conflicting Reports & Gaps
There are discrepancies regarding the reasons behind the leadership changes. While some sources attribute Pazdur's retirement to internal conflicts and politicization within the FDA, others suggest it was a personal decision. Additionally, the exact implications of Michele's reassignment on the approval process for non-prescription drugs remain unclear.
