The CDC delayed publishing a study scheduled for March 19 that found Covid vaccines reduced urgent care and emergency visits by 50 percent and hospitalizations by 55 percent among healthy adults in 2025-2026. Acting CDC Director Jay Bhattacharya halted the report over methodological concerns despite it passing the agency's scientific review process and using the same observational methods the CDC has long employed for respiratory virus vaccines.
