The Weirdo John Stone from Age of Autism agrees that thimerosal is not toxic

You know what I love about John Stone, the resident weirdo at Age of Autism? I love that he thinks he knows science then posts something that he thinks agrees with him when it clearly doesn’t. For example, here is a comment of his in which he thinks that the idea that methylmercury is just as bad as ethylmercury:

“The person who doesn’t do science is Mr Kluger. Here we are from 2013:

Toxicity of ethylmercury (and Thimerosal): a comparison with methylmercury.

Abstract

Ethylmercury (etHg) is derived from the metabolism of thimerosal (o-carboxyphenyl-thio-ethyl-sodium salt), which is the most widely used form of organic mercury. Because of its application as a vaccine preservative, almost every human and animal (domestic and farmed) that has been immunized with thimerosal-containing vaccines has been exposed to etHg. Although methylmercury (meHg) is considered a hazardous substance that is to be avoided even at small levels when consumed in foods such as seafood and rice (in Asia), the World Health Organization considers small doses of thimerosal safe regardless of multiple/repetitive exposures to vaccines that are predominantly taken during pregnancy or infancy. We have reviewed in vitro and in vivo studies that compare the toxicological parameters among etHg and other forms of mercury (predominantly meHg) to assess their relative toxicities and potential to cause cumulative insults. In vitro studies comparing etHg with meHg demonstrate equivalent measured outcomes for cardiovascular, neural and immune cells. However, under in vivo conditions, evidence indicates a distinct toxicokinetic profile between meHg and etHg, favoring a shorter blood half-life, attendant compartment distribution and the elimination of etHg compared with meHg. EtHg’s toxicity profile is different from that of meHg, leading to different exposure and toxicity risks. Therefore, in real-life scenarios, a simultaneous exposure to both etHg and meHg might result in enhanced neurotoxic effects in developing mammals. However, our knowledge on this subject is still incomplete, and studies are required to address the predictability of the additive or synergic toxicological effects of etHg and meHg (or other neurotoxicants).

All bolding is mine, by the way.

I’ve told you before that in vitro (in a lab) is different than in vivo (in an actual organism), and this supports it. But, in the weirdo’s crazy little world, this one study is the Holy Grail of comparing ethyl mercury to methyl mercury. Why? I have no clue. This study confirms that biological systems are more complex than cells in a petri dish, and that we react differently to the ethyl mercury that thimerosal metabolizes into. In essence, we don’t get hurt or become autistic, like anti-vaccine activists and weirdos might want us to believe.

So thank you, John Stone of Age of Autism, for confirming this for us.

What you need to know to fight anti-science activists

A lot of the focus of this blog has been on the anti-vaccine forces out there. That was kind of the original intent since “The Poxes” is kind of a dystopian story of what happens when we just stop vaccinating, cold turkey. (That reminds me that I need to get back to writing that story.) But there are other dangerous lines of thought out there, and I’d like to give you a list of things you need to know to fight them.

We all know that you need a primer on immunology and chemistry to fight the anti-vaccine types. Maybe you can throw in a little toxicology. Knowing these things will help you understand why thimerosal, a chemical that contains mercury, doesn’t behave like mercury alone. It’s not as toxic, and it is delivered in such a small amount that your body deals with it well. A little biology will help you know that you produce more formaldehyde just sitting there reading this and eating fruit than you will ever get through all the recommended vaccines. Again, toxicology will help you understand that your body deals well with those tiny amounts of formaldehyde, and you have nothing to worry about. Continue reading
