Dr. John Mascola, a prominent flu vaccine researcher who stepped into a leadership role at the National Institute of Allergy and Infectious Diseases (NIAID) following Dr. Anthony Fauci's retirement, has reportedly left the agency, according to multiple sources familiar with the matter.
Mascola, who previously served as director of NIAID's Vaccine Research Center, was widely respected for his work on influenza and other infectious diseases. His departure comes amid ongoing changes at the institute, which has been a key player in pandemic preparedness and vaccine development.
NIAID has not officially confirmed the departure or provided details on Mascola's next steps. The institute continues to focus on its mission to conduct research on infectious diseases, including flu and emerging pathogens.
