Pfizer COVID-19 shot expanded to US children as young as 12
U.S. regulators on Monday expanded the use of Pfizer's COVID-19 vaccine to children as young as 12, offering a way to protect the nation's adolescents before they head back to school in the fall and paving the way for them to return to more normal activities. Pfizer's vaccine is being used in multiple countries for teens as young as 16, and Canada recently became the first to expand use to 12 and up. “This is a watershed moment in our ability to fight back the COVID-19 pandemic,” Dr. Bill Gruber, a Pfizer senior vice president who's also a pediatrician, told The Associated Press.
