A former Trump appointee repeatedly urged officials at the Department of Health and Human Services to deliberately allow tens of millions of Americans to become infected with coronavirus. That’s according to Politico, which reports then-science adviser Paul Alexander was promoting a widely discredited approach of herd immunity through natural infection. In one email to top health officials last July, Alexander wrote, “Infants, kids, teens, young people, young adults, middle aged with no conditions etc. have zero to little risk … so we use them to develop herd … we want them infected.” The approach has been condemned by the World Health Organization as highly unethical, with disease experts saying it could result in the deaths of millions of people.
