FDA Is Reviewing Data on Mixing and Matching Boosters, Fauci Says

A study of adults who received booster doses of different Covid-19 vaccines than their original shots has been completed, Fauci said in an interview on Bloomberg Television’s “Balance of Power with David Westin,” and the data have been presented to the U.S. Food and Drug Administration. The National Institutes of Health study looked at the safety, immunogenicity and efficacy of mixing and matching of the three U.S. authorized vaccines for booster purposes. The vaccine from partners Pfizer Inc. and BioNTech SE has been cleared as a booster for vulnerable people, such as the elderly and immunocompromised. Next up for the FDA and the Centers for Disease Control and Prevention is consideration of boosters from Moderna Inc. and Johnson & Johnson.
