PFAS in your blood may be weakening your body's response to the COVID vaccine.
PFAS and Vaccine Effectiveness
A 2026 study found associations between serum PFAS levels and COVID-19 antibody levels in vaccinated adults. Higher PFAS levels were linked to lower antibody responses, suggesting these chemicals suppress immune function even after vaccination.
What You Can Do
Reduce PFAS exposure. Filter water. Avoid nonstick products. Browse non-toxic home essentials.
