Pfizer Says Booster Shots Are Coming. Do Americans Need Them?
Pfizer is trying to convince federal authorities to green-light a COVID booster shot. The COVID-19 vaccine maker began the week by briefing the FDA on the need for a third shot to protect against new variants. Pfizer cites data out of Israel showing a decline in its vaccine effectiveness from more than 90% down to 64% as the Delta variant spreads. But for now, Israel is only offering a third dose to its most vulnerable citizens. Ramping up production would take months. "I don't think we want to be here in December with a new variant that seems to be abating our vaccine and we don't have anything that's in the pipeline all ready to go," Dr. Stephen Schrantz of the University of Chicago Medicine told the Associated Press. #chicago
