When the pandemic hit, America needed someone to turn to for advice. The media and public naturally looked to Dr. Anthony Fauci - the director of the National Institute of Allergy and Infectious Diseases. Unfortunately, Dr. Fauci got major epidemiology and public health questions wrong. Reality and scientific studies have now caught up with him. By pushing vaccine mandates, Dr. Fauci ignores naturally acquired immunity among the COVID-recovered, of which there are more than 45 million in the United States. Mounting evidence indicates that natural immunity is stronger and longer lasting than vaccine-induced immunity. Under Fauci's mandates, hospitals are firing heroic nurses who recovered from COVID they contracted while caring for patients. While anyone can get infected, there is more than a thousand-fold difference in mortality risk between the old and the young. When confronted with the idea of focused protection of the vulnerable, Dr. Fauci admitted he had no idea how to accomplish it, arguing that it would be impossible. Instead, Dr. Fauci has pushed vaccine mandates for children, students and working-age adults who are already immune - all low-risk populations - causing tremendous disruption to labor markets and hampering the operation of many hospitals. Schools are major transmission points for influenza, but not for COVID. Considering the devastating effects of school closures on children, Dr. Fauci's advocacy for school closures may be the single biggest mistake of his career.
