AstraZeneca exec on vaccine rollout in U.S.
Millions of doses of the AstraZeneca COVID-19 vaccine are being administered to some of the world's lowest-income countries thanks in part to the global COVAX initiative. The drugmaker plans to request emergency-use authorization for its vaccine from the Food and Drug Administration when the results of its U.S. clinical trial are available in a few weeks. AstraZeneca executive Ruud Dobber spoke with CBSN's Tanya Rivero about the company's vaccination efforts.
