CDC Delays Report Proving Covid Vaccine Worked Amid RFK Jr. Controversy
A report, cleared by the CDC’s scientific review process and scheduled for publication in the Morbidity and Mortality Weekly Report, utilized the same methodology also employed by numerous leading medical journals to assess vaccine efficacy. This report, obtained by the Post, found that between September and December 2025, healthy adults vaccinated against COVID-19 experienced a 50 percent reduction in urgent care or emergency room visits and a 55 percent decrease in COVID-related hospitalizations compared to their unvaccinated counterparts. The agency had previously published a similar report on the flu vaccine using this methodology.
