US HHS nixes publication of study on COVID vaccine effectiveness

“U.S. health officials stopped the publication of a study on whether the COVID-19 vaccine was keeping adults from becoming sick enough to have to go to the hospital. A U.S. Department of Health and Human Services spokesman on Wednesday confirmed the decision to halt publication, citing a dispute about the study’s methodology. The research paper was to appear in Morbidity and Mortality Weekly Report, the Centers for Disease Control and Prevention’s flagship publication. … the new study concluded that the vaccine cut ER visits and hospitalizations among otherwise healthy adults by about half this past winter, according to The Washington Post, which first reported the cancellation. HHS officials did not say exactly why that methodology was a problem in this instance but argued that prior infection, behavior and differences in who seeks care can affect results.” (04/22/26)
