30 SCIENTIFIC STUDIES THAT DEMONSTRATE VACCINES CAN CAUSE AUTISM

[link to www.facebook.com (secure)]

Evidence that vaccines can cause autism!

It is an often repeated fallacy that there is no research that supports the supposition that vaccines can cause autism. This talking point is most often repeated by medical personnel and public health officials who have simply never been told that these studies exist, and in some cases by those who refuse to read the information when it is offered to them, so they continue to labor under the false assumption that vaccine-autism causation is merely an “internet rumor” or a result of one paper that was published in 1998.

This untruth was again testified to during the HHS Committee hearings

In fact, the first research paper to offer evidence that vaccines may cause autism was THE first paper ever written on autism. In the 1930’s, Child Psychiatrist Leo Kanner discovered 11 children over the course of several years who displayed a novel set of neurological symptoms that had never been described in the medical literature, where children were withdrawn, uncommunicative and displayed similar odd behaviors. This disorder would become known as “autism.” In the paper, Dr. Kanner noted that onset of the disorder began following the administration of a small pox vaccine. This paper, was published in 1943, and evidence that vaccination causes an ever increasing rate of neurological and immunological regressions, including autism, has been mounting from that time until now.

Autistic Disturbances of Affective Contact

Leo Kanner, Johns Hopkins University, 1943

“Since 1938, there have come to our attention a number of children whose condition differs so markedly and uniquely from anything reported so far, that each case merits – and, I hope, will eventually receive – at detailed consideration of its fascinating peculiarities.”

All of Kanners cases were born after, and began to appear following, the introduction of Eli Lilly’s new form of water soluble mercury in the late 1920s used as an anti-fungal in forestry, a wood treatment product in the lumber industry and as a disinfectant and anti-bacterial in the medical industry under the name of “Thimerosal” that was included in vaccines.

For further information on the early evidence of a vaccine/connection, I recommend reading Dr. Bryan Jepson’s book, “Changing the Course of Autism: A Scientific Approach for Parents and Physicians,” as well as Mark Blaxill and Dan Olmseted’s new book “The Age of Autism: Mercury, Medicine, and a Man-made Epidemic.”

As I testified to at the hearing, there is abundant research supporting the vaccine autism link. I have included 49 research papers for your review, and only included research published in the last ten years or so. This is by no means a complete list, but it one that I have been compiling for the last few years as relevant research came to my attention. I have ONLY included autism related information, not research on other vaccine injuries of which there are many.

As you can see, the medical professionals testifying that there is no scientific support for the vaccine/autism causation theory are uninformed about the current state of the science. When vaccination decisions are made based on an uninformed opinion, it means serious potential damage to the patient, and because of the law preventing lawsuits for vaccine injury, it also means that the uninformed medical professionals making bad recommendations CANNOT be held accountable in any way for giving the patient bad information.

Parents want to know if their child can develop autism from their vaccines. If they believe that the answer is yes, and the risk of brain injury from vaccination is higher than their risk from a disease, it is their right to decline vaccination for themselves and their children with out coercion.

Patients MUST be able to make their own informed vaccine decisions, because often, they know more about potential vaccine risks that even top public health officials do.

PURPOSE: Universal newborn immunization with hepatitis B vaccine was recommended in 1991; however, safety findings are mixed. The Vaccine Safety Datalink Workgroup reported no association between hepatitis B vaccination at birth and febrile episodes or neurological adverse events. Other studies found positive associations between

hepatitis B vaccination and ear infection, pharyngitis, and chronic arthritis; as well as receipt of early intervention/special education services (EIS); in probability samples of U.S. children. Children with autistic spectrum disorder (ASD) comprise a growing caseload for EIS. We evaluated the association between hepatitis B vaccination of male neonates and parental report of ASD.

METHODS: This cross-sectional study used U.S. probability samples obtained from National Health Interview Survey 1997-2002 datasets. Logistic regression modeling was used to estimate the effect of neonatal hepatitis B vaccination on ASD risk among boys age 3-17 years with shot records, adjusted for race, maternal education, and two-parent household.

RESULTS: Boys who received the hepatitis B vaccine during the first month of life had 2.94 greater odds for ASD (nZ31 of 7,486; OR Z 2.94; p Z 0.03; 95% CI Z 1.10, 7.90)
compared to later- or unvaccinated boys. Non-Hispanic white boys were 61% less likely to have ASD (ORZ0.39; pZ0.04; 95% CIZ0.16, 0.94) relative to non-white boys.

CONCLUSION: Findings suggest that U.S. male neonates vaccinated with hepatitis B vaccine had a 3-fold greater risk of ASD; risk was greatest for non-white boys.

This new study from France utilizes a new and sophisticated measurement for environmental toxicity by assessing porphyrin levels in autistic children. It provides clear and unequivocal evidence that children with autism spectrum disorders are more toxic than their neurotypical peers.

Excerpt: "Coproporphyrin levels were elevated in children with autistic disorder relative to control groups...the elevation was significant. These data implicate environmental toxicity in childhood autistic disorder."

Abstract: To address a possible environmental contribution to autism, we carried out a retrospective study on urinary porphyrin levels, a biomarker of environmental toxicity, in 269 children with neurodevelopmental and related disorders referred to a Paris clinic (2002–2004), including 106 with autistic disorder. Urinary porphyrin levels determined by high-performance liquid chromatography were compared between diagnostic groups including internal and external control groups. Coproporphyrin levels were elevated in children with autistic disorder relative to control groups. Elevation was maintained on normalization for age or to a control heme pathway metabolite (uroporphyrin) in the same samples. The elevation was significant (P < 0.001). Porphyrin levels were unchanged in Asperger's disorder, distinguishing it from autistic disorder. The atypical molecule precoproporphyrin, a specific indicator of heavy metal toxicity, was also elevated in autistic disorder (P < 0.001) but not significantly in Asperger's. A subgroup with autistic disorder was treated with oral dimercaptosuccinic acid (DMSA) with a view to heavy metal removal. Following DMSA there was a significant (P = 0.002) drop in urinary porphyrin excretion. These data implicate environmental toxicity in childhood autistic disorder.

3. Theoretical aspects of autism: Causes—A review

Journal of Immunotoxicology, January-March 2011, Vol. 8, No. 1 , Pages 68-79

Helen V. Ratajczak, PhD

Autism, a member of the pervasive developmental disorders (PDDs), has been increasing dramatically since its description by Leo Kanner in 1943. First estimated to occur in 4 to 5 per 10,000 children, the incidence of autism is now 1 per 110 in the United States, and 1 per 64 in the United Kingdom, with similar incidences throughout the world. Searching information from 1943 to the present in PubMed and Ovid Medline databases, this review summarizes results that correlate the timing of changes in incidence with environmental changes. Autism could result from more than one cause, with different manifestations in different individuals that share common symptoms. Documented causes of autism include genetic mutations and/or deletions, viral infections, and encephalitis following vaccination. Therefore, autism is the result of genetic defects and/or inflammation of the brain. The inflammation could be caused by a defective placenta, immature blood-brain barrier, the immune response of the mother to infection while pregnant, a premature birth, encephalitis in the child after birth, or a toxic environment.

4. Uncoupling of ATP-mediated Calcium Signaling and Dysregulated IL-6 Secretion in Dendritic Cells by Nanomolar Thimerosal

Environmental Health Perspectives, July 2006.

This study demonstrates that very low-levels of Thimerosal can contribute to immune system disregulation.

Excerpt: "Our findings that DCs primarily express the RyR1 channel complex and that this complex is uncoupled by very low levels of THI with dysregulated IL-6 secretion raise intriguing questions about a molecular basis for immune dyregulation and the possible role of the RyR1 complex in genetic susceptibility of the immune system to mercury."

Abstract

Dendritic cells (DCs), a rare cell type widely distributed in the soma, are potent antigen presenting cells that initiate primary immune responses. DCs rely on intracellular redox state and calcium (Ca2+) signals for proper development and function, but the relationship between these two signaling systems is unclear. Thimerosal (THI) is a mercurial used to preserve vaccines, consumer products, and experimentally to induce Ca2+ release from microsomal stores. We tested ATP-mediated Ca2+ responses of DCs transiently expose to nanomolar THI. Transcriptional and immunocytochemical analyses show murine myeloid immature and mature DC (IDCs, MDCs) express inositol 1, 4, 5-trisphosphate and ryanodine receptor (IP3R, RyR) Ca2+ channels, known targets of THI. IDCs express the RyR1 isoform in a punctate distribution that is densest near plasma membranes and within dendritic processes whereas IP3Rs are more generally distributed. RyR1 positively and negatively regulates purinergic signaling since ryanodine (Ry) blockade (1) recruited 80 percent more ATP responders, (2) shortened ATP-mediated Ca2+ transients >2-fold,(3) and produced a delayed and persistent rise (&#8805;2-fold) in baseline Ca2+. THI (100nM, 5min) recruited more ATP responders, shortened the ATP-mediated Ca2+ transient (&#8805;1.4-
fold) and produced a delayed rise (&#8805;3-fold) in the Ca2+ baseline, mimicking Ry. THI and Ry, in combination, produced additive effects leading to uncoupling of IP3R and RyR1 signals. THI altered ATP-mediated IL-6 secretion, initially enhancing the rate of but suppressing overall cytokine secretion in DCs. DCs are exquisitely sensitive to THI, with one mechanism involving the uncoupling of positive and negative regulation of Ca2+ signals contributed by RyR1.

Abstract

A recent report shows a correlation of the historical use of thimerosal in therapeutic immunizations with the subsequent development of autism; however, this association remains controversial. Autism occurs approximately four times more frequently in males compared to females; thus, studies of thimerosal toxicity should take into consideration gender-selective effects. The present study was originally undertaken to determine the maximum tolerated dose (MTD) of thimersosal in male and female CD1 mice. However, during the limited MTD studies, it became apparent that thimerosal has a differential MTD that depends on whether the mouse is male or female. At doses of 38.4-76.8mg/kg using 10% DMSO as diluent, seven of seven male mice compared to zero of seven female mice tested succumbed to thimerosal. Although the thimerosal levels used were very high, as we were originally only trying to determine MTD, it was completely unexpected to observe a difference of the MTD between male and female mice. Thus, our studies, although not directly addressing the controversy surrounding thimerosal and autism, and still preliminary due to small numbers of mice examined, provide, nevertheless, the first report of gender-selective toxicity of thimerosal and indicate that any future studies of thimerosal toxicity should take into consideration gender-specific differences.

6. Comparison of Blood and Brain Mercury Levels in Infant Monkeys Exposed to Methylmercury or Vaccines Containing Thimerosal

Environmental Health Perspectives, Aug 2005.

Thomas Burbacher, PhD [University of Washington].

This study demonstrates clearly and unequivocally that ethyl mercury, the kind of mercury found in vaccines, not only ends up in the brain, but leaves double the amount of inorganic mercury as methyl mercury, the kind of mercury found in fish. This work is groundbreaking because little is known about ethyl mercury, and many health authorities have asserted that the mercury found in vaccines is the "safe kind." This study also delivers a strong rebuke of the Institute of Medicine's recommendation in 2004 to no longer pursue the mercury-autism connection.

Excerpt: "A recently published IOM review (IOM 2004) appears to have abandoned the earlier recommendation [of studying mercury and autism] as well as back away from the American Academy of Pediatrics goal [of removing mercury from vaccines]. This approach is difficult to understand, given our current limited knowledge of the toxicokinetics and developmental neurotoxicity of thimerosal, a compound that has been (and will continue to be) injected in millions of newborns and infants."

7. Increases in the number of reactive glia in the visual cortex of Macaca fascicularis following subclinical long-term methyl mercury exposure.

The number of neurons, astrocytes, reactive glia, oligodendrocytes, endothelia, and pericytes in the cortex of the calcarine sulcus of adult female Macaca fascicularis following long-term subclinical exposure to methyl mercury (MeHg) and mercuric chloride (inorganic mercury; IHg) has been estimated by use of the optical volume fractionator stereology technique. Four groups of monkeys were exposed to MeHg (50 micrograms Hg/kg body wt/day) by mouth for 6, 12, 18, and 12 months followed by 6 months without exposure (clearance group). A fifth group of monkeys was administered IHg (as HgCl2; 200 micrograms Hg/kg body wt/day) by constant rate intravenous infusion via an indwelling catheter for 3 months. Reactive glia showed a significant increase in number for every treatment group, increasing 72% in the 6-month, 152% in the 12-month, and 120% in the 18-month MeHg exposed groups, and the number of reactive glia in the clearance group remained elevated (89%). The IHg exposed group showed a 165% increase in the number of reactive glia. The IHg exposed group and the clearance group had low levels of MeHg present within the tissue; however, the level of IHg was elevated in both groups. These results suggest that the IHg may be responsible for the increase in reactive glia. All other cell types, including the neurons, showed no significant change in number at the prescribed exposure level and durations. The identities of the reactive glial cells and the implications for the long-term function and survivability of the neurons due to changes in the glial population following subclinical long-term exposure to mercury are discussed.

8. Neuroglial Activation and Neuroinflammation in the Brain of Patients with Autism

Annals of Neurology, Feb 2005.

Diana L. Vargas, MD [Johns Hopkins University].

This study, performed independently and using a different methodology than Dr. Herbert (see above) reached the same conclusion: the brains of autistic children are suffering from inflammation.

Excerpt: "Because this neuroinflammatory process appears to be associated with an ongoing and chronic mechanism of CNS dysfunction, potential therapeutic interventions should focus on the control of its detrimental effects and thereby eventually modify the clinical course of autism."
