I read on the internet that there are dangerous levels of a toxic weed killer in many common vaccines. Is this true? Should I be worried? – Rebecca T., Wilton, CT.
Great question to start off our Ask a Scientist series, Rebecca. Here are the facts:
This claim was posted online by a group called Mom’s Across America (or MAA, which is the guttural noise of frustration that I make after reading their website). I’m not linking to their site because it contains biased anti-GMO, anti-chemical info while also conveniently selling their own line of homeopathic health supplements. They sell a product for “mineral health”, which is not a thing, and it contains “72 essential trance minerals.” Mind you they don’t say what these essential minerals are, nor do they address the fact that there are less then 20 scientifically accepted essential minerals. I think you get the point.
I’ll start by introducing myself and trying to explain why on earth you would trust my opinion. I live in California. I have a Ph.D. in environmental and molecular toxicology. I studied the effects of environmental contaminants on fetal and neonatal health as an academic. I now work in biotech, and it is my job to assess the safety of drugs prior to testing in humans. I don’t work on vaccines currently, and the company I work for does not produce or profit from any pediatric vaccines. I do, however, assess safety for a living, and I am very familiar with how the safety of vaccines is determined.
There is another reason I have educated myself on this topic. I have an autistic daughter.
