The Department of Health and Human Services (HHS) has said that a report showing the efficacy of COVID-19 vaccines has been ?blocked from being published in the U.S. Centers for Disease Control ?and Prevention’s flagship scientific journal. COVID-19 vaccines roughly halved the chances that a U.S. adult would need to visit the emergency room or be hospitalized with their infections last fall and winter, according to two sources familiar with the findings of the study. “Scientific reports are routinely reviewed at multiple levels to ensure they ?meet the highest standards before publication,” HHS spokesperson Andrew Nixon said. Concerns about the “methodological approach estimating vaccine ?effectiveness” meant “the manuscript was not accepted for publication” in the CDC’s ?Morbidity and Mortality Weekly Report (MMWR), he said.
