Abstract Autism is a developmental disability that can cause significant social, communication, and behavioral challenges. Publication types Research Support, U. Gov't, P. Vaccines do not cause autism. Some people have had concerns that ASD might be linked to the vaccines children receive, but studies have shown that there is no link between receiving vaccines and developing ASD. The National Academy of Medicine, formerly known as Institute of Medicine, reviewed the safety of 8 vaccines to children and adults.
The review found that with rare exceptions, these vaccines are very safe. The study focused on the number of antigens given during the first two years of life. The results showed that the total amount of antigen from vaccines received was the same between children with ASD and those that did not have ASD.

One vaccine ingredient that has been studied specifically is thimerosal. Thimerosal is a mercury-based preservative used to prevent germs like bacteria and fungi from contaminating multidose vials of vaccines. Research shows that thimerosal does not cause ASD.
The cause s of autism is unknown. But genetics, differences in brain anatomy, and toxic substances in the environment are thought to contribute to children developing the condition. So how did the idea that vaccines play a role get started? Much of the blame lies with a study published in that suggested that the MMR measles-mumps-rubella vaccine , or infection with the naturally occurring measles virus itself, might cause autism.
