Autism and Thimerosal: a Danish Study

Did the incidence of autism in Denmark decrease after thimerosal-containing vaccines were discontinued in 1992? No; in fact, the incidence of autism rose after 1991, according to this study.

Autism Cases in California After Removal of Thimerosal

This study examined whether the reduction of thimerosal in vaccines administered to infants was associated with a decrease in cases of autism reported to the California’s Developmental Disabilities System (DDS).

Effect of Thimerosal and other Chemicals in Cell Cultures

A new study examined the capacity of various substances to affect growth factor signaling in neuroblastoma (a form of cancerous nerve) cells—an important step in the development of cells of the central nervous system.

Elimination of Methylmercury and Ethylmercury from the Body

This study shows that the mercury contained in some vaccines is handled very differently by the body than mercury found in foods such as fish or the mercury from industrial accidents.

Epidemiological Study on Autism and Thimerosal

Is the hypothesis that thimerosal-containing vaccines cause autism valid? This epidemiological study found no evidence of a cause-effect relationship between the two.

Mercury Concentrations in Immunized Children

Does ethylmercury reach toxic levels in infants immunized with thimerosal-containing vaccines? This study shows that ethylmercury levels in these infants is below toxic levels and is eliminated from the body within two weeks.

Neurodevelopmental Disorders and TCVs

Although this report suggests a link between autism and thimerosal-containing vaccines (TCVs), it has serious methodological limitations that make the results uninterpretable.

Review of Published Data on Thimerosal and Autism

This study analyzed the quality of the evidence assessing a link between thimerosal-containing vaccines (TCV) and autism in the scientific literature. The published epidemiological studies do not demonstrate an association between TCV and autism and data about the pharmacokinetics of thimerosal make such an association less likely.

Thimerosal and Brain Development

Did children exposed to differing amounts of thimerosal develop at the right ages? This study suggests that thimerosal-containing vaccines do not cause autism or significant speech or language disorders.

Thimerosal Exposure and Developmental Disorders

This large prospective study from the UK shows no evidence of any harmful effect of thimerosal-containing vaccines on neurologic or psychological development.

Thimerosal Exposure and Neuropsychological Outcomes

This study looked at 42 neuropsychological outcomes—other than autism—in children who had had varying levels of exposure to thimerosal prior to birth and/or in infancy.

Thimerosal Exposure and Risk of Autism

This large case-control study looked at the relationships between thimerosal-containing injections—either before birth or during infancy—with the development of autism.
