It’s the Midday Healthwatch with Dr. Leana Wen. Yesterday, representatives of nine major drug companies signed a pledge promising not to file for federal approval of a Coronavirus vaccine without subjecting their drugs to long accepted scientific and ethical standards and clinical trials. Usually, we put our trust in institutions like the CDC and the FDA to oversee the safety and efficacy in medicine and the food supply. With nearly 190,000 pandemic deaths and 6.3 million infections nationwide, has that trust been eroded? Dr. Wen is an emergency physician and public health professor at George Washington University. She is a contributing columnist for The Washington Post and a CNN medical analyst. She served as Baltimore's Health Commissioner from 2015-2018.
