This article is written by the autism experts at the Autism Speaks Foundation. It is about what factors in life cause autism. The risk factors range from environmental to genetic. It also mentions who is at higher and who is at lower risk for developing autism. The section of this article dedicated to the no risk; talks about how vaccines play no part in a child developing autism. In conclusion this article will be useful to me when writing my paper, because it is the official autism website, and it specifically states that vaccines do not cause autism.
