One of the most powerful figures at the US Food and Drug Administration (FDA) has admitted she refused the Covid-19 mRNA vaccine while pregnant—even as her agency promoted it as “safe and effective” for all pregnant women.
Dr Sara Brenner’s explosive disclosure, made on 15 May 2025 at the MAHA Institute Round Table in Washington, DC, is as revealing as it is troubling.
A preventive medicine physician, Brenner has worked at the FDA since 2019. As the FDA’s Principal Deputy Commissioner—and briefly its Acting Commissioner—Brenner was at the centre of decision-making.
Prior to that, she was Chief Medical Officer for diagnostics and was detailed to the White House to support the Biden administration’s Covid-19 response. She didn’t just participate in the pandemic response, she helped shape it from within.
“Knowing what I knew—not only about nanotechnology, about medicine, about the medical countermeasures—but also having a very strong and firm grounding in bioethics…there were many things that were not right,” she told the audience.
That someone with her seniority and access to internal data privately rejected the vaccine, while her agency promoted it to millions of pregnant women, presents a profound ethical dilemma.
