US health officials Nix publication of a study on Covid vaccine effectiveness

7 hours ago

U.S. health officials halted publication of a study on COVID-19 vaccine effectiveness in preventing hospitalizations and ER visits.
The study, planned for the CDC's Morbidity and Mortality Weekly Report, used a methodology comparing vaccinated and unvaccinated patients' outcomes.
Officials cited methodological concerns, including prior infection and care-seeking behavior, though experts argue the approach is widely accepted.
The study reportedly found vaccines reduced hospitalizations and ER visits by about half among healthy adults last winter.
Concerns about political interference in CDC publications have arisen, similar to issues during the Trump administration.
