Anthony Fauci knows why COVID-19 vaccines have been so unreliable at halting infection and transmission beyond a few months. He waited until he stepped down as director of the National Institute of Allergy and Infectious Diseases to publicly explain it.
Elsevier's medical journal Cell Host and Microbe published a "perspective" led by Fauci's office last month that shows NIAID had good reason to believe COVID vaccines would fail even before they were authorized, based on research spanning Fauci's 38-year tenure leading NIAID.
U.S.-authorized COVID vaccines, overwhelmingly built on the novel mRNA platform, were designed to provide systemic rather than mucosal immunity, administered in arms rather than noses.
