In 2011, Dr Mercola covered a review by Helen Ratajczak who had analysed all the then available data and was linking the growth of vaccine usage for children in America and the growth of autism.
According to CBS news:
“Ratajczak also looks at a factor that hasn’t been widely discussed: human DNA contained in vaccines… she discusses the increase in autism incidences corresponding with the introduction of human DNA to MMR vaccine, and suggests the two could be linked. Ratajczak also says an additional increased spike in autism occurred in 1995 when chicken pox vaccine was grown in human fetal tissue.”
According to Mercola on autism in American children:
“Rates have exploded from 4 in10,000 children in the 1940s to somewhere between 1 in 50 and 1 in 110 children now, depending on what source of statistics you use. In this literature review, Ratajczak reports approximately one child per 100 (1 percent) in the U.S. currently has an autism spectrum disorder (ASD), and one child per 64 has some form of autism in the United Kingdom.”
In 2013 even the CDC in the USA had the figure as 1 in 50 children with autism. Another study, working with 192 pairs of identical twins, showed that genes were not to blame.
What Mercola also reviews are several possible links between the following and autism:
- Vitamin D deficiency
- Exposure to EMFs during pregnancy
