What this research studies

This work links community water testing with lab experiments to see how PFAS exposure during pregnancy and early life might affect a child's immune system. Researchers will measure PFAS levels in water and biological samples and run animal experiments using pregnant dams to check antibody responses in their offspring after vaccination. They will examine immune cells, the gut microbiome, and how much antibody is passed from mother to baby through the placenta and breast milk. The team will compare older PFAS chemicals and newer ones like PFBS, and study realistic mixtures people encounter.

Who could benefit from this research

Good fit: Pregnant people, new parents, or families with infants living in communities with known PFAS-contaminated drinking water (for example Pittsboro, NC) would be the most relevant candidates for related human studies or sample contributions.

Not a fit: Adults who are not pregnant or caring for infants, and people without meaningful PFAS exposure, are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, the project could identify PFAS that harm infant vaccine responses and guide actions to protect babies and improve drinking water safety.

How similar studies have performed: Previous human and animal studies have linked legacy PFAS to weaker vaccine antibody responses in children, but effects of newer PFAS compounds and real-world mixtures remain largely untested.
