Health and Human Services Secretary Robert F. Kennedy Jr. personally instructed the Centers for Disease Control and Prevention (CDC) to alter language on a webpage concerning the link between vaccines and autism, according to an interview with The New York Times published Thursday, November 21, 2025.
The revised CDC website now states that the assertion "vaccines do not cause autism" is "not an evidence-based claim." This change represents a meaningful departure from decades of scientific research and the established consensus of the medical and scientific communities. The updated page also alleges that government health authorities have historically disregarded a potential connection between vaccines and autism.
