Abstract: 

Across the country and around the world, children are getting sick and dying from preventable diseases—in part because some parents are choosing not to vaccinate their children. Alison Singer, President of the Autism Science Foundation, and Dr. Amy Middleman, Adolescent Medicine Specialist at the University of Oklahoma's Health Sciences Center, examine the science behind vaccinations, the return of preventable diseases, and the risks of opting out. They’re both featured in the PBS NOVA documentary “Vaccines—Calling The Shots,” which airs September 10, at 9 pm, on PBS.

This CDC study casts further doubt on the link between autism and vaccines. The study found no connection between the number of vaccines received and autism risk.

Abstract: 

Paul Offit, award-winning 58-year-old scientist, is hated for his opinion on vaccination. He boldly states — in speeches, in journal articles, and in his 2008 book Autism’s False Prophets — that vaccines do not cause autism or autoimmune disease or any of the other chronic conditions that have been blamed on them. He supports this assertion with meticulous evidence. And he calls to account those who promote bogus treatments for autism — treatments that he says not only don’t work but often cause harm.

In this study prenatal and early-life exposure to ethylmercury from thimerosal-containing vaccines and immunoglobulin preparations was not related to increased risk of ASDs.

CDC Study Shows No Vaccine, Autism Link

Abstract: 

Exposure to thimerosal-containing vaccines in infancy or in the womb is not associated with an increased risk for developing autism, according to a new study from the CDC. The analysis indicated that children with the greatest exposures had slightly lower rates of autism than those who received fewer thimerosal-containing vaccines or none at all.

This new study in the journal of Pediatrics indicated that there was no increased risk of Autism Spectrum Disorder associated with receipt of thimerosal-containing vaccines. The study also found no increased risk for any of the subtypes of Autism Spectrum Disorder, including ASD with regression.  In addition, it found no increased risk of Autism Spectrum Disorder associated with prenatal exposure to thimerosal.  No significant differences in exposure effects were found between boys and girls for any of the ASD outcomes; there was no evidence that higher prenatal exposure exacerbated the effects of post-natal exposure; and there was no evidence that concurrent ethylmercury exposure was associated with ASD. In addition, there was no substantive difference in the association between thimerosal exposure and risk for ASD among children with an older sibling with autism and those without an older sibling with autism.

Vaccine Court Ruling: Thimerosol Does Not Cause Autism

Abstract: 

From the late 1990s to the present, scientists have looked closely at the evidence, and every well-done study has pointed to the same conclusion: thimerosal in vaccines has no link to autism. In one very large Danish study, autism rates rose after thimerosal was removed from vaccines. Another study looking at California, Sweden, and Denmark found the same thing. These results directly contradict the claim that thimerosal causes autism.

Last Friday, a special vaccine court ruled on three cases in which parents were suing on behalf of their autistic children. In each case, the parents claimed that thimerosal had caused their child’s autism. In each case, the Special Master (a judge) ruled definitively against the parents. The result was a slam-dunk win for science.

Mercury-Vaccine Link Disproven in Autism-Study

Abstract: 

A new study provides more proof that childhood vaccines with mercury as a preservative -- no longer on the market -- did not cause autism. It found that the number of autism cases continued to rise through that period even though the preservative thimerosal -- nearly half of which is made of ethylmercury -- was removed from most vaccines in 2001.

Thimerosal, a mercury compound used as a preservative in vaccines administered during infancy, has been suspected to affect neuropsychological development. We compared the neuropsychological performance, 10 years after vaccination, of 2 groups of children exposed randomly to different amounts of thimerosal through immunization. Children who were enrolled in an efficacy trial of pertussis vaccines in 1992–1993 were contacted in 2003. Two groups of children were identified, according to thimerosal content in vaccines assigned randomly in the first year of life (cumulative ethylmercury intake of 62.5 or 137.5 µg), and were compared with respect to neuropsychological outcomes. Eleven standardized neuropsychological tests, for a total of 24 outcomes, were administered to children during school hours. Mean scores of neuropsychological tests in the domains of memory and learning, attention, executive functions, visuospatial functions, language, and motor skills were compared according to thimerosal exposure and gender. Nearly 70% of the invited subjects participated in the neuropsychological assessment (N = 1403). Among the 24 neuropsychological outcomes that were evaluated, only 2 were significantly associated with thimerosal exposure. Girls with higher thimerosal intake had lower mean scores in the finger-tapping test with the dominant hand and in the Boston Naming Test. Given the large number of statistical comparisons performed, the few associations found between thimerosal exposure and neuropsychological development might be attributable to chance. The associations found, although statistically significant, were based on small differences in mean test scores, and their clinical relevance remains to be determined.
