US gives final nod for emergency use of Pfizer Inc’s COVID-19 vaccine

The United States on Friday gave a final go-ahead to the nation’s first COVID-19 vaccine, marking what could be the beginning of the end of an outbreak that has killed nearly 300,000 Americans, according to a person familiar with the decision but not authorized to discuss it publicly. Shots for health workers and nursing home residents are expected to begin in the coming days after the Food and Drug Administration authorized an emergency rollout of what promises to be a strongly protective vaccine from Pfizer Inc. and its German partner BioNTech.
