U.S. Regulators Give Full Approval to Pfizer COVID-19 Vaccine

The FDA's action also may spur more vaccine mandates by companies, universities and local governments.

The U.S. gave full approval to Pfizer's COVID-19 vaccine on Monday, a milestone that may help lift public confidence in the shots as the nation battles the most contagious coronavirus mutant yet. The vaccine made by Pfizer and its partner BioNTech now carries the strongest endorsement from the Food and Drug Administration, which has never before had so much evidence to judge a shot’s safety. More than 200 million Pfizer doses already have been administered in the U.S. — and hundreds of millions more worldwide — since emergency use began in December. “The public can be very confident that this vaccine meets the high standards for safety, effectiveness and manufacturing quality the FDA requires of an approved product,” said acting FDA Commissioner Janet Woodcock. "Today’s milestone puts us one step closer to altering the course of this pandemic in the U.S.”
