Impact of Helminth Infections During Pregnancy on Humoral Vaccine Immunogenicity in Infants
Helminth infection is associated with low vaccine immunogenicity. Pregnant women are particularly sensitive to helminth infection.
Since most vaccines are given shortly after birth, an effect of parasites on infant immunogenicity is of particular concern. Therefore, within this study the investigators aim to investigate if maternal infection influences vaccine immunogenicity in the newborn.
