Proposed Mercury Ban Threatens Vaccines 383

Posted by Soulskill from the ban-venus-too dept.
T Murphy writes "Although in the draft stages, a treaty being pushed by the United Nations Environment Programme has a blanket ban on mercury. While the ban would stop the use of mercury in paints or pesticides, it currently has no exemptions to allow for other small uses, such as in thermisol, which is used as a preservative in vaccines. The next meeting to discuss this treaty will be at the end of October."

    Does anyone really believe that the final draft would include a total ban, even for vaccines? I didn't think so. Sounds like more hype than fact, and an article for the sake of having an article on the part of the Chicago Tribune.

          The point, which I thought was obvious, is that the chlorine is salt is not toxic. Similar to how the mercury in vaccines is not toxic. It is silly to try to extrapolate the chemical behavior of a molecule based on the behavior of the elements that make it up. Otherwise we could all breath water (plenty of oxygen in there right?) or use it to inflate a blimp (with all that hydrogen). Not to mention the fact that even if the mercury in vaccines were bioavailable and had a long half life, the amounts we are talking about are so tiny that you can easily ingest more mercury from a can of tuna than from a years worth of vaccines.

          Meanwhile, I'd like a ban on Monosodium Glutamate (MSG) in restaurants - too many apply the "Essence of Flavor" with a tablespoon (and often will lie about using it at all, when asked) and what MSG does is modify your body chemistry to register flavors more strongly - if that isn't unethical then I give up.

        The (erroneous, and much disproved) argument made by the anti-vaccine crowd is, explicitly, that the thimerosal causes autism. Theirs is a causal hypothesis. Eliminating the cause and getting the negative result would disprove the hypothesis.

    • Thimerosal use in vaccines is already down quite a bit and yet autism cases have not dropped correspondingly. Autism diagnoses continue to increase, even as we use less mercury and fewer heavy metals in products aimed at sensitive populations (at least here in the US and other developed nations).

          Yes, in older kids. The pertussis (whooping cough) component of childhood vaccines wears off after a while (and was never 100% to begin with). This, combined with increasing numbers of non immunized children and the fact that the CDC gets wound up about pertussis* makes outbreaks fairly common.

          Fun fact: the newer tetanus vaccines have pertussis vaccine in them so adults might quit being the reservoir of the disease. It tends to cause a much milder illness in adults so they don't get treated and it can be contagious for weeks.

    Mercury has been phased out of most vaccines. This was done in the late 1990s in response to concerns that the mercury was somehow causing autism in children. Note that this had no impact on autism rates so the anti-vaxxers then switched to talking about ambiguous toxins. Thiomersol is still used in some vaccines but it is only a small fraction of vaccines, such as some versions of the flu vaccine. If necessary that can be easily replaced. It would be stupid because the mercury levels are tiny but it wouldn't have much of an impact. I'm more concerned that this sort of blanket ban would inadvertently impact smaller uses where mercury is really necessary for specialized uses in other areas. The ban also doesn't seem to address the differences between organic and inorganic mercury which have wildly different chemical properties in practice.

    • Wildly different biological properties as well (although that's arguably redundant). The mercury in vaccines isn't bioavailable in any significant way so the body doesn't absorb it like it does atomic mercury. Even more importantly, it doesn't accumulate in the body the way atomic mercury does, any damage the tiny amount of mercury would do is limited to the one or two days it's in your system before it is passed out.

  • Just got my flu shot yesterday, and this year they were using thimerosol-free shots exclusively, whereas in past years I had to specifically ask for one. I'm sure there would be other vax that need it, but reducing it's use whenever possible is a step in the right direction.

    • Thimerosal is used in such low doses that it won't make any difference, really. That and thimerosal is a pretty safe form of mercury, as far as the human body is concerned. As long as there are safe and effective alternatives I support, generally speaking, reductions in use of thimerosal, but if the replacements are less effective and harm the efficacy and affordability of vaccines I say don't throw out the baby with the bath water.

A flu shot without Thimerosal is not only more difficult to store and transport, it's more likely to fail to give you resistance to the flu.

Tuna has elemental (atomic) mercury and compounds that are easily bioavailable: the body will get the mercury out of them, and that's what counts in exposure limits. Non-bioavailable mercury, like in thiomersal, is not included in those limits -- there's no mechanism in our body to break down thiomersal to get at the mercury.

Organic mercury is quite bad compared to elemental mercury. The mercury exposure limits I'm referring to are actually for methyl mercury, since it's the common and dangerous organic mercury.

Obviously, like many products, packaging costs come into play. The single shot vial and the 10 shot vial are the same size and contain the same amount of vaccine.

    I've worked at a vaccines manufacturing site for a dozen years now and have helped produce hundreds of millions of doses of pediatric vaccines - I've never seen a milligram of thimerosal at our plant or any other in our supply chain. Most current technology manufacturing plants stopped using it decades ago and this really is only an issue for old facilities making old vaccines that they can't relicense using new technology.
