Herd immunity: Is it a more compassionate approach or will it lead to death or illness for millions?

As coronavirus cases increase across much of the United States, the Trump administration has reportedly adopted a policy of deliberately letting the virus infect much of the U.S. population in order to attain “herd immunity” — despite warnings from the World Health Organization against such an approach. We host a debate on the contentious issue of herd immunity and how best to confront the virus with two Harvard medical experts: epidemiologist Martin Kulldorff, a professor of medicine at Harvard University and one of the lead signatories of the controversial Great Barrington Declaration arguing for an easing of lockdowns, and Dr. Abraar Karan, an internal medicine doctor at the Brigham and Women’s Hospital and at Harvard Medical School who has worked on the COVID-19 public health response in Massachusetts since February.
