Aluminium in vaccines may cause autism, controversial new research suggests. Autistic children have up to 10 times more of the metal in their brains than what is considered safe in adults, a study found. Study author Professor Chris Exley from Keele University, said: 'Perhaps we now have the link between vaccination and autism spectrum disorder (ASD), the link being the inclusion of an aluminium adjuvant in the vaccine.' The researchers speculate autism sufferers may have genetic changes that cause them to accumulate aluminium which healthy people are able to remove. Research at Keele University, published in the Journal of Trace Elements in Medicine and Biology, provides the strongest indication yet that aluminium is a cause of ASD. The aluminium content of brain tissues from five donors who died with a diagnosis of ASD was found to be extraordinarily high; some of the highest values yet measured in human brain tissue. Why for example, would one of the four major brain lobes of a 15-year-old boy with autism be 8.74 (11.59) micrograms/g dry weight - a value which is at least 10 times higher than might be considered as acceptable for an adult never mind a child? The new evidence strongly suggests aluminium is entering the brain in ASD via inflammatory cells which have become loaded up with aluminium in the blood and/or lymph, much as has been for certain immune cells at injection sites for vaccines that contain aluminium to increase the body's immune response.
