WASHINGTON (Reuters) - U.S. Health Secretary Alex Azar said on Tuesday that if pharmaceutical company Pfizer Inc submits its interim COVID-19 vaccine to health regulators as quickly as expected, the U.S. government now expects to begin vaccinating Americans in December.
Pfizer on Monday said that the vaccine it has been developing with German partner BioNTech SE was 90% effective against COVID-19. It said it expects safety data next week that it needs in order to submit an application for emergency use authorization to the U.S. Food and Drug Administration.
