A former drug company researcher has found a possible link between the MMR vaccine and autism. She has discovered that autism cases rose dramatically after human tissue was added to the vaccines.
Aborted embryo cells are used in the manufacture of 23 vaccines given to infants and children, including the MMR (measles-mumps-rubella) shot – and researcher Helen Ratajczak has detected a sudden rise in autism cases from 1983 onwards when the MMR ‘mark II’ version was introduced.
The later version is contaminated with human DNA from cells, and this could be the cause of the sudden rise, says Ratajczak, formerly a researcher with Boehringer Ingelheim Pharmaceuticals.
Remnants of the DNA have been discovered on the X chromosome in eight genes associated with autism, which could also explain why boys are more likely to develop autism.
