National Institutes of Health: High exposure to radio frequency radiation associated with cancer in male rats

NTP releases final reports on rat and mouse studies of radio frequency radiation like that used in 2G and 3G cell phone technologies.

The National Toxicology Program (NTP) concluded there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today. There was also some evidence of tumors in the brain and adrenal gland of exposed male rats. For female rats, and male and female mice, the evidence was equivocal as to whether cancers observed were associated with exposure to RFR. The final reports represent the consensus of NTP and a panel of external scientific experts who reviewed the studies in March after draft reports were issued in February.

Controversies surrounding mercury in vaccines: autism denial as impediment to universal immunisation

In 2004, the US Center for Disease Control (CDC) published a paper showing that there is no link between the age at which a child is vaccinated with MMR and the vaccinated children’s risk of a subsequent diagnosis of autism (1). One of the authors, William Thompson, has now revealed that statistically significant information was deliberately omitted from the paper (2). Thompson first told Dr S Hooker, a researcher on autism, about the manipulation of the data. Hooker analysed the raw data from the CDC study afresh. He confirmed that the risk of autism among African American children vaccinated before the age of 2 years was 340% that of those vaccinated later. Hooker published his findings in the peer-reviewed open-access journal, Translational Neurodegeneration. However, within hours of CNN publishing the story of the CDC whistle-blower, Hooker’s article was removed from the website of the open-access journal. It was stated that the journal and publisher “believe that its continued availability may not be in the public interest”. The full article is now available only on the PubMed website (3).

The MMR vaccine contains no Thimerosal, but the story of Thompson and the paper on MMR serves to illustrate how disputed the areas of vaccine-related injury and autism have become.

 

A two-phase study evaluating the relationship between Thimerosal-containing vaccine administration and the risk for an autism spectrum disorder diagnosis in the United States

Autism spectrum disorder (ASD) is defined by standardized criteria of qualitative impairments in social interaction, qualitative impairments in communication, and restricted and stereotyped patterns of behavior, interests, and activities. A significant number of children diagnosed with ASD suffer a loss of previously-acquired skills, which is suggestive of neurodegeneration or a type of progressive encephalopathy with an etiological pathogenic basis occurring after birth. To date, the etiology of ASD remains under debate, however, many studies suggest toxicity, especially from mercury (Hg), in individuals diagnosed with an ASD. The present study evaluated concerns about the toxic effects of organic-Hg exposure from Thimerosal (49.55% Hg by weight) in childhood vaccines by conducting a two-phased (hypothesis generating/hypothesis testing) study with documented exposure to varying levels of Thimerosal from vaccinations.

 

A positive association found between autism prevalence and childhood vaccination uptake across the U.S. population.

The reason for the rapid rise of autism in the United States that began in the 1990s is a mystery. Although individuals probably have a genetic predisposition to develop autism, researchers suspect that one or more environmental triggers are also needed. One of those triggers might be the battery of vaccinations that young children receive. Using regression analysis and controlling for family income and ethnicity, the relationship between the proportion of children who received the recommended vaccines by age 2 years and the prevalence of autism (AUT) or speech or language impairment (SLI) in each U.S. state from 2001 and 2007 was determined.
