On Today's Show:
Leana Wen, emergency physician, professor at George Washington University, contributing columnist for The Washington Post, CNN medical analyst, and former Baltimore Health Commissioner, shares her take on the new CDC guidance for vaccinated people, and talks about whether she thinks we'll be hit with a fourth wave of cases, helped along by the many variants, or if enough people will be vaccinated quickly enough to stave it off.
