CDC study on COVID shot benefits blocked

A Centers for Disease Control and Prevention study indicating significant benefits from COVID-19 vaccines has reportedly been blocked from publication by an acting director appointed under the Trump administration. The study, which found that vaccinated healthy adults experienced approximately 50% fewer urgent care visits and hospitalizations, underwent standard scientific review. Critics allege this blockage aligns with an anti-vaccine agenda, potentially undermining public health messaging. The methodology, a test-negative design, is a widely accepted approach for assessing vaccine effectiveness, having been used in numerous previous studies. Concerns have been raised about political interference impacting scientific research at federal agencies.
