The team measured blood serum levels of antibodies for tetanus and diphtheria toxoids in the children at ages five and seven, and compared these levels to those of various PFCs. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) were found to be in the highest concentrations compared to all other PFCs, and were directly associated with lowered antibody counts.
A two-fold increase in PFOS exposure among five-year-old children, for instance, was associated with a 39 percent reduction in anti-diphtheria antibody concentration. And in seven-year-old children, a two-fold increase in PFOA exposure was associated with a 36 percent and 25 percent reduction, respectively, for tetanus and diphtheria antibodies.
“The perfluorinated compounds (PFCs) are highly persistent and cause contamination of drinking water, food, and food chains,” wrote the authors. “If the associations are causal, the clinical importance of our findings is therefore that PFC exposure may increase a child’s risk for not being protected against diphtheria and tetanus, despite a full schedule of vaccinations.”
PFCs are everywhere, as evidenced by a 2004 US government study which found the chemicals in a shocking 98 percent of blood samples taken from a large pool of Americans. So if the chemicals really do inactivate vaccine potential by disabling antibodies, then vaccines may have been shown once again to be medically useless for most Americans.
