How to protect children under 12 from Covid-19, according to Fauci

Dr. Anthony Fauci says there's an important step adults can take to protect children who are too young to be vaccinated against Covid-19. 'The way you protect children who, because of their age, cannot get vaccinated yet is to surround the children -- be it friends, family, school teachers, personnel in the school -- surround the children with vaccinated people,' the director of the National Institute of Allergy and Infectious Diseases told CNN on Sunday.
