Scientists Say That the U.S. Push for Booster Shots Is Premature
Scientists sharply criticized the Biden administration’s push to widely distribute Covid-19 vaccine booster shots in the U.S. next month, saying the data provided by federal health officials this week wasn’t compelling enough to recommend third shots to most of the American population right now.
U.S. health leaders say they are preparing to offer booster shots to all eligible Americans beginning the week of Sept. 20. The plan, outlined Wednesday by CDC Director Dr. Rochelle Walensky, acting FDA Commissioner Dr. Janet Woodcock, White House chief medical advisor Dr. Anthony Fauci and other health officials, calls for a third dose eight months after people get their second shot of either the Pfizer or Moderna vaccines.
They cited three new studies, released by the Centers for Disease Control and Prevention, that showed their protection against Covid diminished over several months. One study in New York from May 3 through July 25 showed that vaccine protection against infection dropped from around 92% to 80%. Another study by the Mayo Clinic showed that Pfizer’s vaccine efficacy fell from around 76% to 42% while Moderna’s declined from 86% to 76%.
