A WNCN news story reports on a real-world CDC vaccine study that raises questions about prioritizing single shots for more people. The study found the two-dose COVID-19 vaccines to be highly effective after the first shot. But if one dose works so well outside of clinical trials, should national and state leaders change their priorities to getting more people that first dose and delaying those second shots?
David Wohl, MD, professor of medicine in the division of infectious diseases, explains how changing course could come with a risk that has to do with timing.
