PFCs may hinder vaccine response. PFCs, Chemicals Widespread in Environment, Linked to Lowered Immune Response to Childhood Vaccinations. Boston, MA — A new study finds that perfluorinated compounds (PFCs), widely used in manufactured products such as non-stick cookware, waterproof clothing, and fast-food packaging, were associated with lowered immune response to vaccinations in children. It is […]
