Scientific consensus from the American Academy of Pediatrics, World Health Organization, and Mayo Clinic confirms that vaccines do not cause autism [1, 5, 9]. Multiple large-scale studies involving millions of children have found no association between the measles-mumps-rubella (MMR) vaccine or vaccine ingredients like thimerosal and autism spectrum disorder [13, 15, 16]. While the CDC recently updated its messaging to suggest that studies have not ruled out all possibilities, this revision is described by health experts as a contradiction of established scientific evidence [8, 10, 11]. Research shows the original claims linking vaccines to autism are based on critically flawed data that have been repeatedly debunked by the global medical community [4, 7, 12, 14]. Experts conclude that the timing of autism diagnoses often coincides with the vaccine schedule but is not caused by it [2, 3].
