Four directors at the National Institutes of Health who were placed on administrative leave earlier this year have now been fired, Science reported.

The ousted leaders led the National Institute of Allergy and Infectious Diseases, the National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the National Institute of Nursing Research. Tara Schwetz, the deputy director for program coordination, planning and strategic initiatives, was also fired. The directors were put on leave in the spring around the same time that the administration laid off thousands at the Department of Health and Human Services.

Science reported that the directors felt they were targeted as part of the administration’s crackdown on diversity, equity and inclusion and for political reasons. Jeanne Marrazzo, the former NIAID director, took over for Anthony Fauci, a frequent target for Republicans who took issue with his approach to the COVID-19 pandemic. Marrazzo filed a whistleblower complaint in early September that in part accused NIH leadership of downplaying the value of vaccines, The New York Times reported.

“It’s not surprising, but it’s still incredibly disappointing,” Marrazzo told Science. “I would have been quite happy to serve under the new administration as long as we were allowed to do our jobs.”
