Does This Shocking CDC Statement Mean Trouble for Pfizer and Moderna?
Coronavirus vaccine leaders Pfizer (NYSE: PFE) and Moderna (NASDAQ: MRNA) announced earlier this year that they'd launched clinical trials of booster shot candidates -- and you could almost hear the world's collective sigh of relief. As coronavirus variants gained ground, everyone's big worry was staying ahead of them. Boosters may help because they offer the already vaccinated person's immune system an extra push.
Moderna has said it aims to bring a booster to market this fall. And Pfizer just last week said it's ready to file for regulatory approval of its third-shot booster candidate in the coming weeks. On the same day as Pfizer's news, the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) delivered a startling message. One that could upset Pfizer's and Moderna's booster plans.
