With regard to the causes of autism , Newschaffer stated in an interview that while genetics plays an important role, that "there are going to be causal components that are nonheritable genetics, things that we refer to as environmental causes..." He has also, however, contended that the rise in autism prevalence is to a large extent due only to "increased community awareness, changes to the diagnostic approach among clinicians and shifting public policy," though he was more ambiguous about this in a 2005 interview, saying that he thought that "there currently is little strong evidence supporting either hypothesis (real risk versus diagnostic bias)...," a view he had expressed  the previous year in an interview with "The New York Times" , saying that "a large chunk" of the rise in autism was due to broadening of the diagnostic criteria but that "The devil is in how big a chunk is that big chunk." Newschaffer has also contended that there is no link between vaccines and autism, saying, "Those studies just kept piling up that showed no association between MMR or thimerosal exposure and autism."
