The U.S. Food and Drug Administration (FDA) has approved updated COVID-19 vaccines from Pfizer-BioNTech and Moderna, targeting the KP.2 variant to better protect against current strains. These vaccines are authorized for individuals aged 6 months and older, with varying dosages based on age and vaccination history. The approval comes as COVID-19 cases rise across the U.S., with increased detections in wastewater and a summer surge in infections. Public health officials recommend getting the new vaccines, particularly for high-risk groups, to prevent a winter surge and reduce the risk of long COVID. The new vaccines are expected to be available in pharmacies and health care facilities within days.
