You write: "but I also trust in body's ability to do what it is designed to do with toxins: excrete them." The body cannot excrete all toxins. Water soluble toxins are, of course, most easily excreted. However, lipophilic toxins are far more difficult to excrete, and some cannot be excreted even with chelation. The body's design is limited in what it can and cannot eliminate with respect to accumulated toxins. It is important that everyone bear this in mind, not only when making decisions regarding vaccinations but when considering our children's environmental toxin load in general. Wouldn't want parents trusting the body's ability to naturally excrete toxins and failing, for example, to contain or safely remove lead paint from the household (and most cases of acute lead poisoning are the result of dust, not chips).
Note that methylmercury and ethylmercury (the metabolized product of thimerosal) are both lipophilic toxins. However, the latter, ethylmercury, is "more lipophilic and therefore potentially more reactive mercurial than either methyl or inorganic Hg" [1]. As for excretion rates, though studies in the past decade reveal that ethylmercury is excreted faster than methylmercury, the jury is still out, and more research is needed to determine whether the effects of ethylmercury toxicity diverge from methylmercury toxicity in other potentially harmful ways. Either way, since both forms are neurotoxic, and studies indicate that ethylmercury is possibly more toxic to the kidneys [2], it is best to apply caution. To that I'd add this: whether one vaccinates or not, there is always risk, one worth assessing and deliberating thoroughly. But please do not simply trust your body's ability to 'cleanse' itself when potentially putting yourself in harm's way. Do not take toxicity lightly--there's a reason why artists are instructed not to smoke or eat food after handling cadmium based paint, and why people are instructed to mop or use a damp cloth to clean lead paint surfaces instead of sweeping or dusting. The list of precautions for avoiding heavy metal toxicity is long because heavy metals and certain other toxins accumulate in the tissues and cannot be effectively eliminated.
