vaccine aluminum exposure - 0 to 18 months
Slide from 'Glyphosate + Aluminum + Mercury + Glutamate = Autism' by Stephanie Seneff, PhD, MIT

From the article, Empirical Data Confirm Autism Symptoms Related to Aluminum and Acetaminophen Exposure by Stephanie Seneff, PhD, Computer Science and Artificial Intelligence Laboratory, MIT, Jingjing Liu, PhD, Computer Science and Artificial Intelligence Laboratory, MIT, and Robert M. Davidson, MD, PhD, Independent Physician and Medical Researcher:


Autism is a condition characterized by impaired cognitive and social skills, associated with compromised immune function. The incidence is alarmingly on the rise, and environmental factors are increasingly suspected to play a role. This paper investigates word frequency patterns in the U.S. CDC Vaccine Adverse Events Reporting System (VAERS) database. Our results provide strong evidence supporting a link between autism and the aluminum in vaccines. A literature review showing toxicity of aluminum in human physiology offers further support. Mentions of autism in VAERS increased steadily at the end of the last century, during a period when mercury was being phased out, while aluminum adjuvant burden was being increased. Using standard log-likelihood ratio techniques, we identify several signs and symptoms that are significantly more prevalent in vaccine reports after 2000, including cellulitis, seizure, depression, fatigue, pain and death, which are also significantly associated with aluminum-containing vaccines. We propose that children with the autism diagnosis are especially vulnerable to toxic metals such as aluminum and mercury due to insufficient serum sulfate and glutathione. A strong correlation between autism and the MMR (Measles, Mumps, Rubella) vaccine is also observed, which may be partially explained via an increased sensitivity to acetaminophen administered to control fever.

Glyphosate and dementia deaths correlation from 'Glyphosate, Deuterium, Prions and Neurodegeneration' by Stephanie Seneff, PhD, MIT

Glyphosate, a carcinogen used heavily in commercial farming and weed control, is everywhere in our environment. It has been found in the air, soil, ground water, drinking water, the food supply, breast milk and vaccines.

From the article, Gut-Wrenching: New Studies Reveal the Insidious Effects of Glyphosate by Pamela Coleman, PhD, a Farm and Food Policy Analyst at The Cornucopia Institute:

Glyphosate is the active ingredient in one of the most heavily used herbicide in the world: Monsanto's Roundup®. The industry claims that Roundup® is quite safe, but authors of a recent article in the scientific journal Entropy reach a very different conclusion:

"Contrary to the current widely-held misconception that glyphosate is relatively harmless to humans, the available evidence shows that glyphosate may rather be the most important factor in the development of multiple chronic diseases and conditions that have become prevalent in Westernized societies."

thimerosal (mercury)

Thimerosal, a powerful neurotoxin, is sometimes used as a preservative or in the manufacturing process of several vaccines. No amount of mercury is safe for human consumption, especially for developing children since it can accumulate in the brain and destroy brain tissue. Vaccines containing thimerosal include the multi-dose influenza vaccines, the tetanus and diphtheria toxoids adsorbed vaccine.

In the article, Thimerosal in Vaccines, the CDC states:

There is no evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site.

That statement is a lie. It also ignores the interaction of thimerosal with aluminum which is used as an adjuvant in many vaccines.

From the article, What Causes Autism by the National Autism Association:

A growing number of scientists and researchers believe that a relationship between the increase in neurodevelopmental disorders of autism, attention deficit hyperactive disorder, and speech or language delay, and the increased use of thimerosal in vaccines is plausible and deserves more scrutiny. In 2001, the Institute of Medicine determined that such a relationship is biologically plausible, but that not enough evidence exists to support or reject this hypothesis. Recent studies have confirmed the association between the use of thimerosal and autism has moved from "biologically plausible" to a "biological certainty" (Boyd Haley). Recent work by Dr. Mark Geier and David Geier in the Journal of American Physicians and Surgeons and Experimental Biology and Medicine have shown strong epidemiological evidence for a causal relationship between thimerosal and neurodevelopmental disorders in children.

Exposure to Mercury and Aluminum in Early Life: Developmental Vulnerability as a Modifying Factor in Neurologic and Immunologic Effects (2015) | National Institutes of Health

Currently, ethylmercury (EtHg) and adjuvant-Al are the dominating interventional exposures encountered by fetuses, newborns, and infants due to immunization with Thimerosal-containing vaccines (TCVs). Despite their long use as active agents of medicines and fungicides, the safety levels of these substances have never been determined, either for animals or for adult humans—much less for fetuses, newborns, infants, and children.


Rigorous and replicable studies (in different animal species) have shown evidence of EtHg and Al toxicities. More research attention has been given to EtHg and findings have showed a solid link with neurotoxic effects in humans; however, the potential synergic effect of both toxic agents has not been properly studied.


The use of Hg [mercury] in pediatrics was broader and left a trail of toxic events of epidemic proportions; first described as “peculiar neurosis of the vegetative nervous system, also known as acrodynia or “pink disease [3]; the wide use of calomel in “worm cures and teething powders [3] made it possible to track and tie acrodynia to Hg toxicity [4]. It is worth mentioning that topical Thimerosal used during pregnancy showed the highest relative risk of malformations compared to other non-mercurial antimicrobials [5]. Despite that, Thimerosal is still used in many pharmaceutical and hygienic products [6]. The continuing use of Thimerosal-containing vaccines (TCVs) in pediatrics (mostly during infancy) is still a matter of concern. In some developed countries, the use of TCVs is restricted to children six months or older. Thimerosal (used in multi-dose vials as an anti-microbial agent) was reduced in some pediatric vaccines in the USA, but it still remains in the majority of influenza vaccines and, with the influenza vaccine being added to the vaccine schedule, it continues to be given to pregnant women, infants, and children in the USA [7].


Indeed, May et al. [11] reported that vaccines contain the highest concentrations of Hg and Al among all biological products (allergenic extracts, inactivated bacterial toxins including toxoids, blood, blood derivatives and others) tested. In the last 30 years, not only has the number of pediatric TCVs increased, but also the Al:Hg ratio, rising from around 10-12-fold [11] to 50-fold in some current vaccines that use Thimerosal at 0.01% [12,13,14].


Although children are more susceptible than adults to toxic effects of heavy metal exposure, fetuses and neonates are even more vulnerable and the least protected by existing regulatory bodies [16]. Therefore, environmental and iatrogenic exposures to neurotoxic chemicals during critical periods of early life—in utero, neonatal and during infancy—are of particular concern. The proper function of the brain depends on the integrity of the whole central nervous system (CNS). Any developmental toxicity capable of affecting optimal development can have life-long consequences [17]; minimal dysfunction can negatively impact quality of life by increasing the risk of health problems and socioeconomic achievements [18]. Subtle neurochemical effects can have a profound and lasting influence on life trajectory [19].


In addition to the multiple exposure studies in Table 1, a number of epidemiological studies found significant dose dependent relationships between Thimerosal administration and medically diagnosed specific delays in development [86,87,88,89]. Also Gallagher and Goodman [90] reported a significant association between TCV exposure from hepatitis B vaccine and developmental disability in U.S. children aged one to nine years. By contrast, other investigators have failed to find a consistent significant relationship between TCV exposure and subsequent specific delays in development in exposed children [91,92]. However, those studies were recently reviewed and it was concluded that their results were uninterpretable [93].

Safety of thimerosal-containing vaccines: a two-phased study of computerized health maintenance organization databases (2003) | National Institutes of Health


In phase I at HMO A, cumulative exposure at 3 months resulted in a significant positive association with tics (relative risk [RR]: 1.89; 95% confidence interval [CI]: 1.05-3.38). At HMO B, increased risks of language delay were found for cumulative exposure at 3 months (RR: 1.13; 95% CI: 1.01-1.27) and 7 months (RR: 1.07; 95% CI: 1.01-1.13). In phase II at HMO C, no significant associations were found. In no analyses were significant increased risks found for autism or attention-deficit disorder.

Thimerosal Exposure in Early Life and Neuropsychological Outcomes 7–10 Years Late (2012) | National Institutes of Health


The authors found no statistically significant associations between thimerosal exposure from vaccines early in life
and six of the seven latent constructs. There was a small, but statistically significant association between
early thimerosal exposure and the presence of tics in boys.

Thimerosal exposure in infants and developmental disorders: a retrospective cohort study in the United kingdom does not support a causal association (2004) | National Institutes of Health


Only in 1 analysis for tics was there some evidence of a higher risk with increasing doses (Cox's HR: 1.50 per dose at 4 months; 95% confidence interval [CI]: 1.02-2.20). Statistically significant negative associations with increasing doses at 4 months were found for general developmental disorders (HR: 0.87; 95% CI: 0.81-0.93), unspecified developmental delay (HR: 0.80; 95% CI: 0.69-0.92), and attention-deficit disorder (HR: 0.79; 95% CI: 0.64-0.98). For the other disorders, there was no evidence of an association with thimerosal exposure.


With the possible exception of tics, there was no evidence that thimerosal exposure via DTP/DT vaccines causes neurodevelopmental disorders.

From the article, The CDC has just published a seismic study linking spontaneous abortions in women to flu vaccines, on the World Mercury Project website:

CDC officially claims that thimerosal is the “safe mercury because it is purportedly excreted quickly from the body. CDC bases this claim solely on its misinterpretation of data from a poorly designed study conducted in the early 2000s by an industry insider, Dr. Michael Pichichero. Subsequent studies have proven that the ethylmercury in thimerosal is actually far more persistent in organs than the methylmercury in fish (Burbacher et al.) (Rodrigues et al.).
