This is either a fake post, or you are strongly misinformed.
Autism is NOT CAUSED by vaccinations. It has been proven time and time again in scientific research that vaccinations are NOT related to autism.
Autism seems to be a genetic disorder that may have an environmental trigger, which is not vaccinations.
Autism is partially genetic and is not curable through the application of chlorite vapour. Being an Autistic adult myself, I would strongly argue that in many cases there is nothing to cure, Autism is a beautiful thing in its own work, although living with an Autistic person can be very hard work
This question hits upon an incredibly important issue. Autism is a developmental disability and, although a cure would be wonderful, there is no scientifically valid evidence that one exists. There are cases of an individual losing a diagnosis because their communicative and social skills develop to the point that they don't meet the DSM criteria but there isn't a drug that you can take or a therapy that you can go through that will cure autism. In fact some therapies, like the one described here, can be quite harmful or dangerous. I advise very strongly against introducing any therapy of this kind. There is no reason whatsoever to believe that it will be beneficial and there is a very real possibility that it will cause harm.
Autism can not be cured. If this child was cured, he did not have autism. And I've never heard of autism occuring at the age of 10.
