Top Pfizer, Moderna execs at odds on need for 4th COVID-19 vaccine dose


Top executives at pandemic juggernauts Pfizer and Moderna are at odds on the need for a fourth COVID-19 vaccine dose. One says a second booster is needed “right now,” while the other thinks a fourth mRNA shot may only be essential for older adults and the immunocompromised.

Based on what Pfizer has seen, it's 'necessary' for a 'a fourth booster right now,” Bourla said over the weekend.
