PCB Exposure and Vaccines

In an article in MedPage Today titled " PCB Exposure Attenuates Two Vaccines' Efficacy", it is stated, "The potency of diptheria and tetanus vaccination can be attenuated by children's exposure to the pollutant poluchlorinated biphenyl (PCB)" according to researchers in Denmark.

The study included two cohorts of children born in the Faroe Islands of Denmark, where PCB levels, but not dioxin, are known to be high, which may be in part because whale blubber is a traditional food of this region.

Every doubling in total PCB exposure reduced antibody response to the diphtheria vaccine by nearly a quarter in younger children and reduced tetanus vaccine response similarly in older children.
