Neue Studie: Autismus durch Impfungen

[mirijam]

Eine kürzlich von Wissenschaftlern im US-Bundesstaat Pennsylvania durchgeführte Studie brachte ans Licht, dass viele Affenbabys, die im Rahmen neuer Forschungsprojekte geimpft wurden, anschließend Autismus-Symptome zeigten.

Im Rahmen ihrer Analyse unternahmen Laura Hewitson und ihre Kollegen an der University of Pittsburgh im US-Bundesstaat Pennsylvania die Sicherheitsüberprüfung an normalen Impfstoffen für Kinder. Solche Prüfungen durchzuführen wäre eigentlich die Aufgabe der US-Gesundheitsbehörde Centers for Diesease Control and Prevention (CDC), doch von offizieller Seite sind sie nie erfolgt.

Die Studie wurde beim International Meeting for Autismus Research (IMFAR) in London vorgestellt.

Ergebnisse der Studie: junge Makake-Affen, die die von der CDC seit den 1990er-Jahren empfohlenen Impfungen erhielten – und zwar genau in der Dosis, die ihrem Alter und Gewicht entsprach – entwickelten mit höherer Wahrscheinlichkeit Autismus-Symptome. Bei ihren nicht geimpften Artgenossen traten solche Anzeichen nicht auf. Das ist ein klarer Hinweis auf einen engen Zusammenhang zwischen Impfstoffen und autistischen Störungen.

"Infant Monkeys Given Standard Doses of Vaccines Develop Autism Symptoms

Infant Vaccines Produce Autism Symptoms in New Primate Study by University Of Pittsburgh Scientists

Routine Safety Study That Government Scientists Refused to Do Illustrates Vaccine Program and Mercury Health Risks

Atlanta, GA: Findings released today showed that infant monkeys given vaccines officially recommended by the CDC and the American Academy of Pediatrics (AAP) exhibited autism-like symptoms. Lead investigator Laura Hewitson of the University of Pittsburgh and colleagues presented study results at the International Meeting for Autism Research (IMFAR) in London. Safety studies of medicines are typically conducted in monkeys prior to use in humans, yet such basic research on the current childhood vaccination regimen has never before been done.

The abstracts presented at IMFAR, the world’s top autism science conference, describe biological changes and altered behavior in vaccinated macaques that are similar to those observed in children with autism. Unvaccinated animals showed no such adverse outcomes. The vaccines given were those recommended for U.S. infants in the 1990s, including several with the mercury preservative thimerosal and the Measles-Mumps-Rubella vaccine. Rates of autism spectrum disorder among children born in the 1990s surged dramatically, from about 1 in 5,000 to 1 in 150 children.

“This research underscores the critical need for more investigation into immunizations, mercury, and the alterations seen in autistic children,” stated Lyn Redwood, director of SafeMinds. “SafeMinds calls for large scale, unbiased studies that look at autism medical conditions and the effects of vaccines given as a regimen.”

The group’s request for research echoes that of Dr. Bernadine Healy, Former NIH Director, in a CBS interview earlier this week. She asserted that public health officials have been too quick to dismiss an autism-vaccine connection when the research has been insufficient. The government recently conceded a federal vaccine court case which agreed that a child regressed into autism as a result of 9 vaccines given on one day.

“The full implications of this primate study await publication of the research in a scientific journal,” noted Theresa Wrangham, president of SafeMinds. “But we can say that it demonstrates how the CDC evaded their responsibility to investigate vaccine safety questions. Vaccine safety oversight should be removed from the CDC and given to an independent agency.”"

Abstract

The neurotoxic organomercurial thimerosal (THIM), used for decades as vaccine preservative, is a suspected factor in the pathogenesis of some neurodevelopmental disorders. Previously we showed that neonatal administration of THIM at doses equivalent to those used in infant vaccines or higher, causes lasting alterations in the brain opioid system in rats. Here we investigated neonatal treatment with THIM (at doses 12, 240, 1440 and 3000 μg Hg/kg) on behaviors, which are characteristically altered in autism, such as locomotor activity, anxiety, social interactions, spatial learning, and on the brain dopaminergic system in Wistar rats of both sexes. Adult male and female rats, which were exposed to the entire range of THIM doses during the early postnatal life, manifested impairments of locomotor activity and increased anxiety/neophobia in the open field test. In animals of both sexes treated with the highest THIM dose, the frequency of prosocial interactions was reduced, while the frequency of asocial/antisocial interactions was increased in males, but decreased in females. Neonatal THIM treatment did not significantly affect spatial learning and memory. THIM-exposed rats also manifested reduced haloperidol-induced catalepsy, accompanied by a marked decline in the density of striatal D₂ receptors, measured by immunohistochemical staining, suggesting alterations to the brain dopaminergic system. Males were more sensitive than females to some neurodisruptive/neurotoxic actions of THIM. These data document that early postnatal THIM administration causes lasting neurobehavioral impairments and neurochemical alterations in the brain, dependent on dose and sex. If similar changes occur in THIM/mercurial-exposed children, they could contribute do neurodevelopmental disorders.
