FALSE

The scientific consensus, supported by decades of rigorous research and prominent health organizations such as the American Academy of Pediatrics, the Mayo Clinic, and the Autism Science Foundation, consistently maintains that there is no causal link between vaccines and autism. Although the Centers for Disease Control and Prevention's public messaging underwent a revision in late 2025 that cast doubt on this stance, medical experts and scientific bodies have characterized this change as a distortion of existing evidence rather than a reflection of new scientific findings. Critical analyses of the original studies that proposed a link have found them to be fraudulent or methodologically flawed, while comprehensive epidemiological studies have repeatedly failed to demonstrate any association between vaccine administration or ingredients and the development of autism spectrum disorder.
