This article is a bunch of hooey and half-truths. Europeans have approved tiny amounts of squalene in some vaccines, including the new H1N1 vaccine, after appropriate testing and years of use. I don't discount a certain amount of concern about vaccines in general, and always encourage people to be advocates for themselves, but let's stick to facts. There is NO squalene in US vaccines. There is a tiny and much reduced amount of thimerosal in live attenuated flu vaccines, because they do have to preserve the vaccine somehow. No scientific evidence links thimerosal to any problems. (Go to CDC website for more info on this topic.)
Even so, children or anyone with Down’s syndrome or other mitochondrial defects might be susceptible to vaccine injury by another means. The immune system and nervous system are slammed hard by vaccines, especially combined vaccines like MMR and DTP. Defense requires active mitochondria, which have not fully matured in young children and are weakened in Down’s syndrome.
