Alex Azar, head of the Department of Health and Human Services (HHS), said on Monday that by the end of January, some 50 million Americans could have received their first shot of the Pfizer-BioNTech COVID-19 vaccine.
Azar made the remarks at a vaccine kickoff event at the George Washington University Hospital, which received its first shipment of the vaccine on Monday morning. Developed by Pfizer and German partner BioNTech, the COVID-19 vaccine won emergency use authorization on Friday.
