A Comparative Study Evaluating the Dose-Responsiveness Effects of methylmercury and Thimerosal on Select Nervous, Immune and Enzyme Parameters 


Deborah Keil, Ph. D. Medical Univeristy of South Carolina 

Grant Abstract:

Infantile autism (IA) is a neurodevelopmental syndrome found in 1-5 cases of every 10,000 children with boys acquiring this syndrome 3-5 times more than girls.

The spectrum of disorders of autism includes a range of impaired development of language and communication, unusual behaviors, and mental retardation.

A diversity of pathophysiological effects also exist to include hyperserotoninemia, decreased T-cell proliferative function and activation, increased soluble IL-2 levels in serum, decreased CD8+ cells, decreased NK cells, development of anti-brain autoantibodies, decreased cerebellum volume and Purkinje cell number. Several studies indicate that the etiology of IA is multi-factorial and includes exposure to environmental chemicals. In particular, mercury exposure during infant and child development has been implicated in IA, especially in the case of vaccines containing mercury.

Although mercury exposure from vaccines has been implicated in autism, this association has been criticized due to a lack of supportive experimental dose-response data. Thus, the proposed study will assess the possible role of methylmercury (MeHg) and thimerosal (TH) in contributing to the pathophysiology of IA using a mouse model to assess dose-responsive effects in cognitive and physiological parameters that encompass nervous, immune and enzyme pathways.

This comparative approach will permit increased understanding of deficits due to MeHg or TH after acute exposure during early developmental stages and facilitate understanding of etiological causes of autism or other neurodevelopmental diseases.

Furthermore, this study will also improve our understanding of the health effects attributed to different forms of mercury and contribute to the development of toxicological risk assessment models for detecting environmental contaminants that would adversely impact children’s health.

Vaccines Do Not Cause Autism


Note/Warning:

Autistic people have fought the inclusion of ABA in therapy for us since before Autism Speaks, and other non-Autistic-led autism organizations, started lobbying legislation to get it covered by insurances and Medicaid. 

ABA is a myth originally sold to parents that it would keep their Autistic child out of an institution. Today, parents are told that with early intervention therapy their child will either be less Autistic or no longer Autistic by elementary school, and can be mainstreamed in typical education classes. ABA is very expensive to pay out of pocket. Essentially, Autism Speaks has justified the big price tag up front will offset the overall burden on resources for an Autistic’s lifetime. The recommendation for this therapy is 40 hours a week for children and toddlers.

The original study that showed the success rate of ABA to be at 50% has never been replicated. In fact, the study of ABA by United States Department of Defense was denounced as a failure. Not just once, but multiple times. Simply stated: ABA doesn’t workIn study after repeated study: ABA (conversion therapy) doesn’t work. 

What more recent studies do show: Autistics who experienced ABA therapy are at high risk to develop PTSD and other lifelong trauma-related conditions. Historically, the autism organizations promoting ABA as a cure or solution have silenced Autistic advocates’ opposition. ABA is also known as gay conversion therapy.


The ‘cure’ for Autistics not born yet is the prevention of birth. 

The ‘cure’ is a choice to terminate a pregnancy based on ‘autism risk.’ The cure is abortion. This is the same ‘cure’ society has for Down Syndrome. 

This is eugenics 2021. Instead of killing Autistics and disabled children in gas chambers or ‘mercy killings’ like in Aktion T4, it’ll happen at the doctor’s office, quietly, one Autistic baby at a time. Different approaches yes, but still eugenics and the extinction of an entire minority group of people.


Fact: You can’t cure Autistics from being Autistic.

Fact: You can’t recover an Autistic from being Autistic.

Fact: You can groom an Autistic to mask and hide their traits. Somewhat. … however, this comes at the expense of the Autistic child, promotes Autistic Burnout (this should not be confused with typical burnout, Autistic Burnout can kill Autistics), and places the Autistic child at high risk for PTSD and other lifelong trauma-related conditions.


[Note: Autism is NOT a disease, but a neurodevelopmental difference and disability.]


Fact: Vaccines Do Not Cause Autism.
