Autism : responding to parents' questions and concerns about vaccines
Provides links to resources for parents regarding autism and the safety of measles-mumps rubella (MMR) vaccine.
Autism Spectrum Disorders (ASDs)
Provides links to resources discussing the hypothesis that vaccines cause autism.
Talking about Vaccines: Autism
Claims that vaccines cause autism have led some parents to delay or refuse vaccines for their children. The most common claims are that autism is caused by MMR vaccine, vaccines that contain thimerosal, or too many vaccines. Many studies have been done to test these claims. None has shown that vaccines cause autism. The webpage links to journal articles and other resources for health care professionals and parents.
Autistic spectrum disorder : no causal relationship with vaccines
Reviews recent controversies surrounding immunizations and ASD (austic spectrum disorder).
Les troubles envahissants du développement : aucune relation causale avec les vaccins
Le présent article analyse de récentes controverses entourant l’immunisation et les troubles envahissants du développment (TED) et conclut qu’aucune donnée n’appuie une association entre ces deux éléments.
NICHD Autism Research Information
The US National Institute of Child Health and Human Development (NICHD) is one of many federal entities involved in autism spectrum disorder (ASD) research. NICHD's portfolio covers a variety of topics in autism, including autism etiology, epidemiology, treatment, and screening. The institute also supports professional training and the development of research infrastructure that will facilitate research in ASD and other intellectual and developmental disabilities.
A look at what causes, and doesn't cause, autism
Examines the fear held by some parents that the combination measles-mumps-rubella vaccine (MMR) causes autism. Summarizes the Wakefield studies (studies that support the notion that MMR causes autism), studies showing that MMR vaccine does not cause autism, and other studies on the causes of autism.
Evidence Shows Vaccines Unrelated to Autism
Claims that vaccines cause autism have led some parents to delay or refuse vaccines for their children. The most common claims are that autism is caused by measles-mumps-rubella (MMR) vaccine, vaccines that contain thimerosal, or too many vaccines. Many studies have been done to test these claims. None has shown that vaccines cause autism. This sheet lays out the facts to help parents understand why experts do not think vaccines cause autism.
Thimerosal and autism
Provides a summary of the evidence showing that, while some things do cause autism, mercury in vaccines is not one of them.
Prenatal and infant exposure to thimerosal from vaccines and immunoglobins and risk of autism
This study was designed to examine relationships between prenatal and infant ethylmercury exposure from thimerosal-containing vaccines and/or immunoglobin preparations and Autism spectrum disorder. There were no findings of increased risk.
