Study of total population showing no change to Autism despite completely stopping to vaccinate. (PMID: 15877763)
“RESULTS:
The MMR vaccination rate in the city of Yokohama declined significantly in the birth cohorts of years 1988 through 1992, and not a single vaccination was administered in 1993 or thereafter. In contrast, cumulative incidence of ASD up to age seven increased significantly in the birth cohorts of years 1988 through 1996 and most notably rose dramatically beginning with the birth cohort of 1993.
CONCLUSIONS:
The significance of this finding is that MMR vaccination is most unlikely to be a main cause of ASD, that it cannot explain the rise over time in the incidence of ASD, and that withdrawal of MMR in countries where it is still being used cannot be expected to lead to a reduction in the incidence of ASD.”

“The committee rejected a causal relationship between the MMR vaccine and autism as well as a causal relationship between thimerosal-containing vaccines and autism.”
Review of autistic children shows no regression that is related to the MMR vaccine. PMID: 16729252
“There was no evidence that onset of autistic symptoms or of regression was related to measles-mumps-rubella vaccination. The implications of these findings for the existence of a ‘regressive phenotype’ of ASD are discussed.”
No difference in developmental disorders despite not being exposed to thimerosal. Fombonne E, et al., Pediatrics. 2006; 118(1): e139-50
“CONCLUSIONS:
The prevalence of pervasive developmental disorder in Montreal was high, increasing in recent birth cohorts as found in most countries. Factors accounting for the increase include a broadening of diagnostic concepts and criteria, increased awareness and, therefore, better identification of children with pervasive developmental disorders in communities and epidemiologic surveys, and improved access to services. The findings ruled out an association between pervasive developmental disorder and either high levels of ethylmercury exposure comparable with those experienced in the United States in the 1990s or 1- or 2-dose measles-mumps-rubella vaccinations”
No association between Thimerosal and autism. Hviid, et al., Journal of the American Medical Association. 2003; 290(13):1763-6
“CONCLUSION:
The results do not support a causal relationship between childhood vaccination with thimerosal-containing vaccines and development of autistic-spectrum disorders.”
Increase in autism when thimerosal was discontinued showing no correlation. PMID: 12949291
“CONCLUSIONS:
The discontinuation of thimerosal-containing vaccines in Denmark in 1992 was followed by an increase in the incidence of autism. Our ecological data do not support a correlation between thimerosal-containing vaccines and the incidence of autism.”
Thimerosal-containing vaccines do not cause autism. Stehr-Green P, et al., American Journal of Preventive Medicine. 2003;
“CONCLUSIONS:
The body of existing data, including the ecologic data presented herein, is not consistent with the hypothesis that increased exposure to Thimerosal-containing vaccines is responsible for the apparent increase in the rates of autism in young children being observed worldwide.”
Levels of mercury in children after receipt of thimerosal-containing vaccines. Pediatrics Feb 2008, Volume 121.
After 5 days there were no detectable mercury levels, the half-life of intramuscular ethyl mercury is substantially shorter than that of oral methyl mercury.
Lower rate of autism in children vaccinated with the MMR vaccine vs those that are unvaccinated. Budzyn D, et al., The Pediatric Infectious Disease Journal.
“RESULTS:
For children vaccinated before diagnosis, autism risk was lower in children vaccinated with MMR than in the nonvaccinated (OR: 0.17, 95% CI: 0.06-0.52) as well as to vaccinated with single measles vaccine (OR: 0.44, 95% CI: 0.22-0.91). The risk for vaccinated versus nonvaccinated (independent of vaccine type) was 0.28 (95% CI: 0.10-0.76). The risk connected with being vaccinated before onset of first symptoms was significantly lower only for MMR versus single vaccine (OR: 0.47, 95% CI: 0.22-0.99).
CONCLUSIONS:
The study provides evidence against the association of autism with either MMR or a single measles vaccine.”
