• The study analyzed data from 2001 to 2007 across all 50 U.S. states and found that a one percent increase in vaccination uptake correlated with an additional 680 cases of autism or SLI.
• Researchers found a strong link between aluminum, a common adjuvant in vaccines, and autism, especially in the years following the reduction of thimerosal-containing vaccines.
• A review proposes a new model where vaccines might trigger an immune response in individuals with pre-existing vulnerabilities, potentially leading to regressive autism.
• The review suggests a need for further research to understand the complex relationship between vaccines, immune system dysregulation and autism, moving away from a simplistic cause-and-effect model.

Researchers have uncovered a potential link between childhood vaccinations and the increasing prevalence of autism in the United States. A study published in the Journal of Toxicology and Environmental Health, Part A found a positive association between the proportion of children receiving recommended vaccinations and the rate of autism or speech or language impairment (SLI) in different U.S. states.

The study focused on vaccination uptake rates and autism prevalence across all 50 U.S. states from 2001 to 2007. Using statistical methods, it analyzed the relationship between these two variables, controlling for factors like family income and ethnicity.

The results were startling: The higher the proportion of children that received recommended vaccinations by age two years, the higher the prevalence of autism or SLI. The paper further revealed that for every one percent increase in vaccination uptake, there was an additional 680 cases of autism or SLI reported in each state.

What makes this finding particularly interesting is that the association held true even after accounting for other factors that could potentially influence the results. For instance, the researchers found no significant relationship between vaccination rates and other disabilities, nor was there any correlation between the number of pediatricians in a state and vaccination rates.

These findings suggest that despite the removal of mercury-containing preservatives, specifically thimerosal, from many vaccines in recent years, other components or the overall process of vaccination may still be linked to autism.

The thimerosal-autism connection

Thimerosal is a chemical preservative that contains ethyl mercury, one of two forms of mercury humans are commonly exposed to. Mercury is a naturally occurring element that is toxic to humans in certain forms and amounts.

Thimerosal has been widely used as a preservative in vaccines to prevent bacterial and fungal contamination. However, recent studies and public health concerns have led to a reevaluation of its safety and its eventual removal from most childhood vaccines in the U.S. in 2001. (Related: Autism begins during pregnancy, may be caused by mercury in dental amalgam and Thimerosal in flu shots, warns science paper.)

Exposure to mercury has been linked to a range of health problems, including:

• Degenerative nerve cell damage: Mercury is a potent neurotoxin that can damage nerve cells and cause neurodegenerative conditions like Alzheimer’s disease.
• Behavioral changes: Studies have found that exposure to mercury can cause adverse behavioral changes.
• Impaired brain development: Mercury can interfere with brain development, especially in young children.
• Developmental delays: In severe cases, mercury exposure can cause mental retardation and cerebral palsy, particularly in fetuses and young infants.

The debate over thimerosal in vaccines gained momentum when some studies suggested a link between thimerosal-containing vaccines and neurodevelopmental disorders like autism. Analysis of data from the U.S. Centers for Disease Control and Prevention‘s (CDC) Vaccine Adverse Event Reporting System (VAERS), which tracks vaccine side effects, shows a significant association between thimerosal-preserved vaccines and these disorders.

Infants and young children are particularly vulnerable to mercury toxicity because of their immature detoxification system and underdeveloped blood-brain barrier. Since most of their detox organs are still developing, they may not be as effective at removing toxic compounds like ethyl mercury from the body.

Similarly, the blood-brain barrier, which protects the brain from harmful substances, is not fully developed in infants, allowing mercury to easily reach the brain and cause serious damage.

Aluminum in vaccines also linked to autism

Aluminum is a toxic metal that is often used in vaccines as an adjuvant. Adjuvants are meant to enhance the recipient’s immune response after receiving the vaccine. Like mercury, aluminum is a potent neurotoxin that can accumulate in the brain, eventually killing nerve cells and causing neurodegenerative diseases like Alzheimer’s.

In a study published in the journal Entropy, American researchers reported finding “strong evidence supporting a link between autism and the aluminum in vaccines.” They analyzed data from VAERS and found a strong link between autism and aluminum exposure, especially in the years after mercury was phased out of vaccines. It was around that time that childhood vaccination recommendations began including six additional doses of aluminum-containing vaccines.

The researchers reported that mentions of autism in the VAERS database increased steadily in the late 1990s and early 2000s, coinciding with the rise in aluminum content in vaccines. The team also identified several symptoms that became more common in vaccine reports after the year 2000, including cellulitis (a bacterial skin infection), seizures, depression, fatigue, pain and even death. These symptoms were more commonly associated with aluminum-containing vaccines, cementing aluminum as the root cause of toxicity.

Interestingly, the study was able to establish a link between autism and two specific vaccines, namely the measles, mumps and rubella (MMR) vaccine and the hepatitis B (Hep-B) vaccine. The researchers reported that the MMR vaccine “was highly over-represented in the cases associated with autism,” while most of the symptoms linked to Hep-B vaccination in children under six years old were also associated with aluminum-containing vaccines. (Related: The corrupt medical establishment and the vaccine industry doesn’t want you to see these studies, which link VACCINES to AUTISM.)

These findings further bolstered their belief in the contribution of aluminum adjuvants to the development of autism in vaccinated children. They also noted that the strong association between Hep-B vaccination and autism suggests the possibility of aluminum and mercury working synergistically to induce toxicity, given that some Hep-B vaccines still contained thimerosal at the time.

Vaccines and regressive autism

In a more recent article published in the Journal of Autism and Epilepsy, Dr. Sarah Crawford, a professor at Southern Connecticut State University‘s Department of Biology, explored the complex interplay between vaccines, the immune system and autism. Her review delved into a specific subset of autism called regressive autism, which is characterized by the sudden loss of previously acquired skills (e.g., speech and social skills), often accompanied by seizures, within the first one to three years of life.

Some parents and researchers have observed that this regression often occurs shortly after vaccine administration, raising questions about a potential link. However, despite these observations, there is a glaring lack of studies establishing a causal connection between vaccines and autism.

Crawford’s review takes a different approach, focusing on recent genetic studies that have uncovered a significant overlap between immune system components affected in autism and those essential for vaccine-induced immunity. This overlap suggests a possible connection between vaccines and autism, but not necessarily in the way many might think.

The immune system plays a critical role in the development and function of the central nervous system (CNS), particularly during the early years of life when the brain is rapidly maturing. Recent research has shown that individuals with autism often exhibit immune system dysregulation, which could affect the normal development of the CNS.

In this context, the article proposes a new model for understanding vaccine-related autism. According to Crawford, vaccine-associated regressive autism (VARA) may occur when individuals influenced by pre-existing genetic or environmental factors that predispose them to immune system dysfunction are exposed to vaccines. These predisposing factors could include genetic variations, environmental toxins or other as-yet-unknown factors.

The administration of vaccines could potentially trigger an immune response in these at-risk individuals that disrupts normal CNS development. This disruption could lead to the sudden loss of developmental milestones and other symptoms associated with regressive autism.

This model challenges the traditional view that vaccines directly cause autism in all children. Instead, it suggests that vaccines might interact with pre-existing vulnerabilities in certain individuals, leading to the observed rapid regression in some cases. (Related: Over 300 pages of evidence from the CDC show that vaccines cause autism.)

Crawford emphasizes the importance of further research to better understand the complex interplay between vaccines, the immune system and autism. As her review suggests, the relationship between vaccines and autism is far more complex than previously thought, and a deeper understanding of this complex interplay is essential for the health and well-being of future generations.
