Excerpts: The incidence and prevalence data indicate the timing of introduction of vaccines and changes in the type and increasing number of vaccines given at one time implicate vaccines as a cause of autism.
Autism in the United States spiked dramatically between 1983 and 1990 from 4–5/10,000 to 1/500. In 1988, two doses of MMR II were recommended to immunize those individuals who did not respond to the first injection. A spike of incidence of autism accompanied the addition of the second dose of MMR II. Also, in 1988, MMR II was used in the United Kingdom, which reported a dramatic increase in prevalence of autism to 1/64 (noted above). DOWNLOAD PDF STUDY, JOURNAL OF IMMUNOTOXICOLOGY
