⁉️Q: Do Vaccines Cause Autism?
✖️ A: No, there is no known link! The idea that the childhood vaccine against measles, mumps, and rubella (MMR) causes autism is based on a discredited study that inaccurately linked the MMR vaccine to autism in a small group of children.
When it was discovered that the lead scientist lied and falsified the data, the findings from this study were removed. Many rigorous studies by other groups found no link between the MMR vaccine and autism. Similarly, the small amounts of thimerosal, a vaccine preservative present in a small number of vaccines, has also been shown to have no relationship to autism.
Rates of autism have continued to rise even though thimerosal ceased to be used as a preservative in routine childhood vaccines decades ago.
