Early-Life Lead Exposure Weakens Immune Responses to Vaccinations, New Study Finds

A recent study published in the American Journal of Epidemiology has identified critical periods during early life when lead exposure can significantly diminish children’s antibody responses to routine vaccinations. The research found that increased lead levels in the first three weeks after birth are associated with a notable decrease in anti-tetanus antibody levels, while exposure around the time of birth (one week before to one week after) correlates with reduced anti-diphtheria antibody levels.

New Study: Metabolism-Disrupting Chemical Mixtures, Folic Acid Supplementation, and Liver Injury and Steatosis in Mother-Child Pairs

A new study by researchers from the Icahn School of Medicine at Mount Sinai reveals that prenatal exposure to environmental chemicals and endocrine disruptors may pose significant risks to liver health for both mothers and their newborns. Additionally, the researchers found that treating folic acid and other B vitamin deficiencies in pregnancy may help counter some of the adverse effects of prenatal exposures on the livers of children.
