That was never a theory. That's why I know you have never taken a science class, and you have never looked at the scientific method.
There are two meanings to the word 'theory.' That is the way you use it - it's an idea that someone presents without proof. However, when the word is used in science, it means that something has been proven to be fact. Nobody ever proved that autism was the result of vaccinations. It was a conspiracy theory. A conspiracy theory and a theory in science are two very different things.
QUOTE; Although solid scientific research continues, in an attempt to find explanations and solutions, a number of nonscientific and pure myths about autism have emerged. Myths that vaccines or mercury are associated with autism have been amplified by misguided scientists; frustrated, but effective parent groups; and politicians. Preventing the protection provided by vaccination or administration of mercury-chelating agents may cause real damage to autistic individuals and to innocent bystanders who as a result may be exposed to resurgent diseases that had already been “extinguished. ” That such myths flourish is a consequence of the authority of scientific evidence obtained by scientific methodology losing ground to alternative truths and alternative science. This article presents a narrative of the origin of the myths around autism.
