A panel of experts advising the Food and Drug Administration weighs the safety and effectiveness of the COVID-19 vaccine from Moderna in a daylong public meeting. A committee vote will guide the FDA's decision about authorizing the vaccine for emergency use during the pandemic. At the same time, NPR will have a live video stream of the House Committee on Oversight and Reform hearing examining the alleged role of Purdue Pharma and members of the Sackler family in the opioid epidemic. [Note from KPR: both events are provided on the same video feed and it is unclear which will be shown at what time.]
