US Health Officials Nix Publication of a Study on COVID Vaccine Effectiveness

U.S. health officials blocked the publication of a COVID-19 vaccine effectiveness study that was scheduled to appear in the CDC's flagship journal, the Morbidity and Mortality Weekly Report. The Department of Health and Human Services justified stopping the research by questioning its methodology, despite the fact that this same scientific approach has been widely accepted and published in prestigious medical journals. The blocked study had found that vaccination reduced emergency room visits and hospitalizations among healthy adults by approximately fifty percent during the previous winter.
