US regulators give full approval to Pfizer COVID-19 vaccine
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.
