The determination of reliable sources in relation to determining the scientific consensus is whether or not they are independent, third party sources with no reason outside of scientific validity for coming to such conclusions. That is not the case here, all the studies you've cited "disproving" a link have financial ties with the vaccine manufacturers, such as the AAP, the people who did the study in the New England Journal of Medicine etc. The JAMA study in Denmark was done by people with ties to vaccine manufacturer Statens Serum Institut, and omitted 10-25% of Autistic cases in the earlier findings to give the illusion of a constant rate of Autism increase after thimerosal was removed in 1992, even though today the Autism ratio is 1 in 1500 as opposed to 1 in 500 then. The AAP, the website where almost all the other studies are described has considerable ties to the vaccine industry as do Immunization branches of public health. If you want to examine a fringe minority position, include only independent researchers in the controversy and then make the evaluation over which side can be considered "fringe."
