The US Food and Drug Administration launched a new unified platform for analyzing adverse event reports. This platform — called the FDA Adverse Event Monitoring System (AEMS) — represents a major achievement in the agency’s mission to modernize and provide radical transparency into the safety of regulated products. “The FDA’s previous adverse event reporting systems were outdated and fragmented and made important data difficult to access. These clunky systems also wasted millions of taxpayer dollars and created blind spots in our postmarket surveillance of products ranging from drugs and vaccines to cosmetics,” said FDA Commissioner Marty Makary, M.D., M.P.H. “We’re fixing the problem through a major modernization initiative. Starting [March 11, 2026], the FDA will have a single, intuitive adverse event platform that will better serve agency scientists, researchers, and the public.”
