This 1997 documentary from CNBC exposed the link between the polio vaccine and rare cancers like mesothelioma and childhood cancers. Dr. Maurice Hilleman, a vaccine scientist who worked for Merck, admitted on video that he suspected that the polio vaccine would cause cancer. He suspected this because of the known presence of monkey viruses in the vaccine, specifically a virus called SV40. This virus has been found in the tumors of many cancer patients who had the polio vaccine, and also the children of those who received it.
