“The perceived link between childhood vaccines and autism has generated significant press and controversy since 1992.The suggested link has been, and is today, the MMR vaccine. Since 1983, the MMR vaccine in the US has only been produced using aborted fetal cells. Coincidentally, severe autism began to rise in the US in 1983, increasing from less than 1 child per 10,000 to 16-17 children per 10,000 (or about 1 in 500) by 1990. The aborted fetal produced MMR was introduced to the UK almost a decade later, and an immediate rise in autism levels was noted, which lead to the suspected link between the vaccine and autism.
International studies have been performed to refute this link, focusing on Thimerosal (mercury) found in the vaccine’s buffer, and on the measles component of this vaccine. Studies that have been conducted have not found an association between mercury or the measles component and autism. The published conclusions, including a recent Washington Post story, have been that the MMR vaccine is therefore not linked to autism. And yet, parents remain fearful and unconvinced, and justifiably so. The only conclusions that can be drawn from the studies that have been done is that neither mercury nor the measles virus in the vaccine can be associated with autism.One cannot conclude from the studies that there is no link between this vaccine and autism.
I find it fascinating, perplexing really, that such a broad conclusion ‘MMR vaccine is not linked to autism’ has nevertheless been spread to the public, to the scientific community and to public officials. No well designed studies, either retrospective or prospective, have been done to truly examine this potential link. No studies have been done to examine the link between vaccines containing human aborted fetal DNA and epidemic levels of diseases such as autism.
How might the human DNA contaminated vaccines contribute to human disease? First, there is the potential for the contaminating DNA to be mixed with our own genes by a process called homologous recombination. Homologous recombination is an established biologic phenomenon in which a segment of a cell’s DNA is substituted by another segment of DNA that is similar. This can occur during cell division or DNA repair.
Homologous recombination occurs naturally to create genetic diversity in our offspring, and is also conveniently harnessed by scientists to introduce experimental DNA into cells or animals. We do not yet know if this occurs with the contaminating human DNA found in some of our vaccines, and if so, to what extent. Imagine the potential consequences of human DNA from a vaccine, a vaccine that is given to children at an average age of 15 months, being incorporated into a child’s developing brain.
One does not need to be a rocket scientist to know that this potential has to be studied. In addition to the potential for homologous recombination, DNA is known to be a powerful immune stimulant. Diseases like graft versus host, juvenile (type I) diabetes, multiple sclerosis, lupus and some forms of arthritis are what are called auto-immune diseases. What these are are diseases driven by immune attack from our own immune system on our own organs, a system normally responsible to attack invading bacteria and pathogens. Targeted self-destruction, if you will.”
