There is not a link between immunizations and autism. The very small study that originally reported this link has been proven to be completely untrue. The physician who reported this study has lost his license as a result.
Autism Spectrum Disorders (ASD) Causes
The causes of autism spectrum disorders (ASD) have been hotly debated. While scientists suspect that both genetics and environment play a role, there is no certainty about what's behind this group of neurological disorders. Research continues, searching for the causes.

See All 3 AnswersGenetics is a clear part of autism, but not all of the genetic risk is inherited. Some of the genetic changes that lead to autism are de novo, which means mutations in the egg or sperm.

Joane Goodroe , Nursing, answeredAccording to the CDC, research does NOT show any link between the type of mercury in vaccines and autism. They also point out that the mercury was taken out of childhood vaccines in 2001 and the rates of autism have continued to climb.

William Stillman , Health Education, answeredSee All 2 AnswersThere is no prenatal test to determine autism in a fetus in utero; however, as various environmental factors are under research investigation for autism causation, the wise mother will closely monitor what she eats, drinks, breathes, and topically applies to her skin as she should to ensure the overall health of her baby no matter its way-of-being in the world. -

The Dan Marino Foundation answeredThe causes of PDD-NOS are still unknown. There is a strong belief in the medical community that that the disability’s origin is genetic and/or biological and affects brain function, but specific biological mechanisms remain unclear. There is a possibility that more than one variable could be responsible for the different symptoms that are present in those individuals with PDD-NOS.
There are no factors in a child’s upbringing that are responsible for PDD-NOS. Parents do not cause PDD-NOS.

A recent study published that was conducted in the Netherlands found more children with autism lived in a high tech IT sector. These findings follow a theory called the "hyper-systemizing" theory of autism. This theory proposes that people with autism have a strong desire to understand the workings of systems, the researchers said. Such skills are valued in IT-related fields, including engineering, physics, computing and mathematics. The outcome of the study was the need to study more information in this area.
