Winter storms delay COVID-19 vaccine shipments

Winter storms have impacted deliveries of coronavirus vaccines in all 50 states. Several vaccination sites have had to close due to a lack of doses. This comes as a new study raises questions about how many doses of the Pfizer vaccine are actually needed. Dr. Amesh Adalja, an infectious disease expert and senior scholar at Johns Hopkins University's Bloomberg School of Public Health, joined CBSN with the latest on the nation's vaccination efforts.

Vaccine trials for pregnant women, children

Pfizer and BioNTech are launching the first clinical trial in the U.S. to look at how the coronavirus vaccine affects pregnant women, and also announced plans for a clinical trial of the vaccine in children. They also submitted new data to the FDA showing that the vaccine can safely be stored at more moderate temperatures. CBSN's Tanya Rivero spoke with Dr. Leo Nissola, a physician and immunotherapy scientist, about the latest developments.

Winter storms delay COVID-19 vaccinations

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.
