PFAS may impact immune response to vaccines, studies suggest
by Katherine McMahon,Sarah Howard on October 4, 2024 at 10:14 pm
A recent study published in Environmental Research found that adults with higher exposure to PFAS developed fewer antibodies after receiving their third COVID-19 booster. “While factors such as age, sex, and underlying health conditions have been studied extensively, research on the potential impact of environmental factors, such as PFAS exposure, on the SARS-CoV-2 mRNA vaccine response remain limited.”
