Ask The Doctors: WHO Recommends Fully Vaccinated Wear Masks

The Delta variant is driving lockdowns in countries throughout the Asia-Pacific region, and now the World Health Organization is recommending that fully vaccinated people wear masks, splitting off from current CDC guidance. How is the Delta variant impacting us here at home, and how do we protect ourselves and others as we prepare to celebrate July Fourth?

We take listener questions on vaccines and variants with Dr. Philip Landrigan, a pediatrician, public health physician, epidemiologist, and Director of the Program for Global Public Health and the Common Good at Boston College, and Dr. Sabrina Assoumou, an assistant professor of medicine at Boston University's School of Medicine and infectious disease specialist at Boston Medical Center.
