A fair and square PEG

Anti-vaxers like to get all heated up over the notion that there is antifreeze in vaccines. Actually, this is not true: there is a precipitating agent in many vaccines called polyethylene glycol (PEG), which only bears a passing resemblance to ethylene glycol, aka antifreeze. PEG can be found in a variety of household and medicinal substances, such as toothpaste, laxatives and skin creams.

Interestingly enough, though, PEG not only has very low toxicity upon ingestion, it may even help repair cell membranes after traumatic brain injuries :

PEG eliminates the amyloid precursor protein (APP) that builds up as a result of traumatic axonal brain injuries. When this protein begins to accumulate, cells begin to die.

Not only does research find PEG benefiting brain injuries, but studies have also shown that it has helped repair nerve membranes after spinal cord injuries in guinea pigs. While PEG has been tested on animals up to this point, a good deal of the research has promising human application.

Take that and stick in your pipes, anti-vaxers. 😀

  1. Ethylene glycol, polyethylene glycol… ethyl mercury, methyl mercury…carbon dioxide, carbon monoxide… whassa difference?

    I was interested to see that the vaccinetruth page you linked to included in its page on the dangers of “antifreeze” in vaccines the summary of an article from the European Journal of Dermatology. The article appears to be about allergic reactions to various components of vaccines. It makes no mention of ethylene glycol, or even polyethylene glycol that I could see, but looks specifically at other components of vaccines. The article is available free in the full-text version, yet they don’t bother to actually link to it.

    In short, the only scientific citation made on the page has zilch to do with “antifreeze” or PEG.

    My best guess is that it’s there to befuddle the easily befuddled.

    Keep up the good work, Esther.

  2. Thanks, Squillo. I actually didn’t peruse every source that particular website provided, as I was merely searching for an antivax site that asserted antifreeze was used in vaccines. But excuse me if I don’t exactly fall over in shock to find that an antivax website misuses sources…par for the course, as we well know.

  3. I think it’s kind of funny that antivaxers portray themselves as not having been tricked into vaccinating like the rest of the sheeple…and then they turn around and parrot untruths that they could easily discover if they had two brain cells and enough intellectual rigor to care about getting it right.

  4. isles – Yup 🙂 .

  5. Typhoid Jenny still claims that vaccines contain anti-freeze and ether. But her science advisor, Dr. Jay Gordon, admitted earlier this year that vaccines contain neither.
