The more children are exposed to perfluorinated compounds (PFCs), the less likely they are to have a good immune response to vaccinations, according to new research. The finding suggests that the chemicals can affect children’s immune system enough to make them more vulnerable to infectious diseases.
PFCs are used in nonstick coatings, stain-resistant fabrics, and food packaging. They can persist in the environment for many years.
NPR reports:
“Normally, a vaccine causes the production of lots of antibodies to a specific germ. But ... the response to tetanus and diphtheria vaccines was much weaker in 5-year-olds whose blood contained relatively high levels of PFCs ... The health effects of PFCs are still poorly understood. But in the past decade, government scientists have become increasingly concerned about possible links to developmental problems in children.”
