After a more than 13-year period of stability with Janet Woodcock as the head of CDER, with Patrizia Cavazzoni taking charge during the next four years of former U.S. President Joe Biden’s tenure, the FDA division has had no fewer than five different people in charge throughout 2025. Up to bat now as acting director is Tracy Beth Høeg, a physician and epidemiologist who co-authored a paper in 2022 with CBER Director Vinay Prasad, FDA Commissioner Marty Makary and others demonstrating that COVID-19 boosters and college vaccine mandates were harmful to young men due to myocarditis risks.
