New Study Shows Mercury in Vaccines Causes Brain Damage

A new paper published online in the Journal of Neurochemical Research concludes that:

• low doses of Thimerosal in vaccines are associated with neurotoxic effects;

• no studies have been carried out on the combination of Thimerosal with aluminium adjuvants in such Thimerosal containing vaccines;

• animal studies show mercury accumulates in the brain in the metallic [inorganic] form [ie mercury as Hg];

• that the doses in vaccines are sufficient potentially to affect brain neuro development;

• the doses in vaccines given to infants have been shown to be toxic in in vitro experiments on cultured human brain cells and in animals;

• the continued use of Thimerosal in vaccines is counter-intuitive.

This new paper follows on from a recent paper published last year which concluded that:

exposure to thimerosal during early postnatal life produces lasting alterations in the densities of brain opioid receptors along with other neuropathological changes, which may disturb brain development.“

And do vaccines cause autistic conditions?  If you read nothing else we strongly recommend you read this: PDF Download – Text of May 5th 2008 email from US HRSA to Sharyl Attkisson of CBS News].  In it the US Health Resources Services Administration [HRSA] state to CBS News reporter Sharyl Attkisson

We have compensated cases in which children exhibited an encephalopathy, or general brain disease. Encephalopathy may be accompanied by a medical progression of an array of symptoms including autistic behavior, autism, or seizures.”

Despite all the lies and deceit by health official worldwide, the question “do vaccines cause autism” was answered after the Hannah  Poling story broke in the USA in February 2008 [see CHS article here].  Hannah developed an autistic condition after 9 vaccines administered the same day.  Under the media spotlight numerous US health officials and agencies conceded on broadcast US nationwide TV news from CBS and CNN. Full details with links to the original sources can be found in this CHS article: Vaccination Causes Autism – Say US Government & Merck’s Director of Vaccines. [Blue Text added 10 April 2011]

Integrating Experimental (In Vitro and In Vivo) Neurotoxicity Studies of Low-dose Thimerosal Relevant to Vaccines José G. Dórea Published online 25 February 2011 – Journal of  Neurochemical Research DOI: 10.1007/s11064-011-0427-0Online First™.

There is a need to interpret neurotoxic studies to help deal with uncertainties surrounding pregnant mothers, newborns and young children who must receive repeated doses of Thimerosal-containing vaccines (TCVs). This review integrates information derived from emerging experimental studies (in vitro and in vivo) of low-dose Thimerosal (sodium ethyl mercury thiosalicylate). Major databases (PubMed and Web-of-science) were searched for in vitro and in vivo experimental studies that addressed the effects of low-dose Thimerosal (or ethylmercury) on neural tissues and animal behaviour. Information extracted from studies indicates that: (a) activity of low doses of Thimerosal against isolated human and animal brain cells was found in all studies and is consistent with Hg neurotoxicity; (b) the neurotoxic effect of ethylmercury has not been studied with co-occurring adjuvant-Al in TCVs; (c) animal studies have shown that exposure to Thimerosal-Hg can lead to accumulation of inorganic Hg in brain, and that (d) doses relevant to TCV exposure possess the potential to affect human neuro-development. Thimerosal at concentrations relevant for infants’ exposure (in vaccines) is toxic to cultured human-brain cells and to laboratory animals. The persisting use of TCV (in developing countries) is counterintuitive to global efforts to lower Hg exposure and to ban Hg in medical products; its continued use in TCV requires evaluation of a sufficiently nontoxic level of ethylmercury compatible with repeated exposure (co-occurring with adjuvant-Al) during early life.

Abstract of M Olczak et al Neonatal Administration of Thimerosal Causes Persistent Changes in Mu Opioid Receptors in the Rat Brain

Abstract Thimerosal added to some pediatric vaccines is suspected in pathogenesis of several neurodevelopmental disorders. Our previous study showed that thimerosal administered to suckling rats causes persistent, endogenous opioid-mediated hypoalgesia. Here we examined, using immunohistochemical staining technique, the density of l-opioid receptors (MORs) in the brains of rats, which in the second postnatal week received four i.m. injections of thimerosal at doses 12, 240, 1,440 or 3,000 lg Hg/kg. The periaqueductal gray, caudate putamen and hippocampus were examined. Thimerosal administration caused dosedependent statistically significant increase in MOR densities in the periaqueductal gray and caudate putamen, but decrease in the dentate gyrus, where it was accompanied by the presence of degenerating neurons and loss of synaptic vesicle marker (synaptophysin). These data document that exposure to thimerosal during early postnatal life produces lasting alterations in the densities of brain opioid receptors along with other neuropathological changes, which may disturb brain development.
