This is an interesting article from GreenMed on how bacteria can help dotoxify the body of harmful toxins, including toxins from vaccines.
[t]he unintended adverse health effects of vaccines often far exceed their purported benefits. This is especially true for so-called "attenuated" live vaccines, such as oral polio vaccine, which have recently been linked to tens of thousands of cases of childhood vaccine-induced paralysis in countries like India. Oral Saccharomyces boulardii, a beneficial form of yeast, has been found in an animal model to prevent oral polio vaccine-induced IgA nephropathy, a form of immune-mediated kidney damage. Additionally, probiotic bacteria have been found to positively regulate the two poles of immunity (TH1/TH2), which vaccines often upset by inducing hypersensitization via over-activation of the adaptive/humoral (TH2) pole of immunity.
