London: The world’s first vaccine to help control symptoms of autism has been developed. The vaccine was created by Canada’s University of Guelph researchers for gut bacteria common in autistic children which will help control symptoms of autism.

More than 90% of children with autism spectrum disorders suffer from chronic and severe gastrointestinal symptoms of which 75% suffer from diarrhea. The scientists have now developed a carbohydrate-based vaccine against the gut bacteria Clostridium bolteae which is known to play a role in gastrointestinal disorders.
