““We have worked closely with the FDA to ensure that Americans will have access to Moderna’s updated, bivalent booster, which, if authorized, may offer higher, broader, and more durable protection against Covid-19 compared to the currently authorized booster,” said Moderna Chief Executive
Moderna started a clinical trial earlier this month of its new booster shot. Pfizer and BioNTech said they would start a study of their new shot this month.
Until clinical trial data are available, Moderna said t it is asking the FDA to authorize the shot based on a study of an earlier vaccine targeting the original and Omicron BA. 1 strains that produced strong antibody responses against the BA. 4 and BA. 5 strains compared with its currently available booster shot.
