Pfizer said Thursday it is tweaking its COVID-19 vaccine formula to create a shot that targets the Delta variant. Pfizer is also planning to request emergency authorization in the U.S. next month for a booster shot of its vaccine, saying an early study showed a third dose raised neutralizing antibody levels in patients. On Thursday, the Centers for Disease Control and Prevention and the Food and Drug Administration issued a rare joint statement saying they won’t rely exclusively on drug company data to make a decision on booster shots.
