According to a study published in PLoS Medicine (August 2006), PCB’s (polychlorinated biphenyls) are being shown to cause immune response failures which correspond to a blocking response to vaccinations.

What researchers found was that 25% of the children in the Faroe Islands who were inoculated for tetanus had no protection from the vaccinations. This concurs with animal model studies which have shown general immune deficiencies being generated by the exposure to other organic pollutants like dioxin as well as PCB’s

We already know that these pollutants can cause cognitive damage to children but add this immunologic effect and you can see how our continued disregard for our environment spells nothing but disaster for human kind.
