What to know about COVID-19 study that was finally published after being blocked by CDC - ABC News - Breaking News, Latest News and Videos
Overview
ABC News published an explainer about a COVID-19 vaccine effectiveness analysis that CDC leadership had blocked from internal publication but was later published in JAMA Network Open. The peer‑reviewed paper reported about a 50% reduction in emergency department visits and roughly 55% effectiveness against hospitalization last winter. The episode, covered by ABC News, has renewed scrutiny of how federal public‑health agencies review and control release of vaccine research and raised broader concerns about transparency and scientific communication.
