SCIENTISTS ARE FINALLY BEGINNING TO MAKE HEADWAY UNDERSTANDING THE REALCAUSES OF AUTISM. YET MILLIONS REMAIN UNCONVINCED BY THE EVIDENCE.

Although study results vary, research has found that as many as one percent of all US children have an ASD. How are all those children stricken? What actually causes autism? A quick Web search for “autism” reveals an array of answers, only some of which are supported by scientific research. An advertisement at the top of my search results on Google led me to an official-looking website arguing forcefully that autism is caused by minute quantities of thimerosal found in some vaccines, despite the fact that no reputable study has ever shown a causal link between vaccines and autism. The site contended that studies disputing the relationship between autism and vaccines containing thimerosal were poorly constructed. It also cited Andrew Wakefield’s 1998 study on the correlation between the measles, mumps, and rubella (MMR) vaccine and autism. But Wakefield’s study involved just 12 children, was later retracted, was complicated by conflicts of interest, and may have been fraudulent. Yet after all that, the site offered no hard evidence supporting a causal link between vaccinations and autism! Even if the Wakefield study wasn’t seriously flawed, it could never have shown that vaccines cause autism. So what do larger, rigorously constructed studies have to say about the roots of ASD?
