Over 56 million people in the U.S. have received at least one dose of a COVID-19 vaccine, but millions more need to be administered in order for the nation to achieve herd immunity. Meanwhile, the Centers for Disease Control and Prevention expects severe weather to continue to cause widespread delays in vaccine shipments over the next few days. “CBS This Morning” lead national correspondent David Begnaud reports on one California hospital that has vaccinated over 90% of its employees, and Dr. Susannah Hills, a pediatric airway surgeon and an assistant professor at New York-Presbyterian/Columbia University, joined CBSN to discuss the latest on the pandemic.
