Can an iron pill boost a Mom's vaccine protection for her baby?

This study investigated whether taking iron supplements helps pregnant women build a stronger immune response to important vaccines. Researchers compared the vaccine responses of 171 pregnant women who were anemic and received treatment-dose iron supplements to women who were not anemic and received a lower, preventive dose. The goal was to see if correcting iron deficiency leads to better protection from vaccines like tetanus, diphtheria, and COVID-19 for both the mother and her baby.
