Pfizer says vaccine has been granted priority review

Pfizer leaders say its coronavirus vaccine has been granted priority review by the US Food and Drug Administration, and the agency will decide whether or not to give it full approval for people 16 and older by January 2022. More people in the United States have received Pfizer's vaccine than any other in the country. Some hope that a full approval of a coronavirus vaccine will encourage people who have been reluctant to get vaccinated.
