A New Chapter: Peter Marks, Former FDA Vaccine Czar, Lands at Eli Lilly

In a move sending ripples across the biopharmaceutical landscape, Dr. Peter Marks, the highly respected former director of the Food and Drug Administration's Center for Biologics Evaluation and Research (CBER), has officially joined pharmaceutical powerhouse Eli Lilly. This transition, effective October 7, 2025, marks a significant shift for a figure instrumental in navigating the U.S.

through the complexities of vaccine and gene therapy development, particularly during the unprecedented challenges of the COVID-19 pandemic.

Dr. Marks' tenure at the FDA was defined by his steadfast leadership and deep scientific expertise. As the head of CBER, he oversaw the approval process for vaccines, blood products, and advanced therapies, playing a crucial role in the rapid development and authorization of COVID-19 vaccines and treatments.
