– Anthony S. Fauci, MD ICYMI: Fauci announced that he’s stepping down from the following positions in December: director of the National Institute of Allergy and Infectious Diseases (NIAID), chief of the NIAID Laboratory of Immunoregulation, and chief medical advisor to President Biden. During his tenure, he’s helped save countless lives and researched treatments for illnesses like HIV, tuberculosis, Ebola, and Zika. Some hated him (remember all the COVID-19 drama?) and others loved him. No matter how you feel, he’s done some super important work, and we thank him for his service.
