Pfizer-BioNTech, Moderna Covid-19 Boosters for All Adults Backed by FDA, CDC

Booster shots from Pfizer Inc. and partner BioNTech SE and Moderna Inc. will be available to all adults after the Centers for Disease Control and Prevention endorsed the extra doses for people at least six months after their second shot.

The signoff Friday by CDC Director Rochelle Walensky will lead to a significant widening of the U.S. booster campaign that health officials hope will remove confusion and offer people more protection ahead of holiday gatherings and travel as new daily Covid-19 cases are beginning to rise again.
