PRINCETON - New Jersey has the highest autism diagnosis rate in the nation and now many parents across the state are left to question its cause after a study linking the disorder to vaccines was called a fraud.

Officials say one in every 94 children born in the Garden State is diagnosed with autism. Parents like Marie Gary say they took precautions with childhood vaccinations after a British doctor claimed they could cause the disorder.

Gary's 17-year-old son Scott is autistic and she says that with her second child, she spread out scheduled vaccinations.

Gary's son attends the Eden Institute, which is a private school for autistic students in Princeton. The institute recommends that parents stagger vaccinations, but also emphasizes that there is no known cause for the emotional and behavioral disorder.
