Vaginal Microbiome Seeding and Health Outcomes in Cesarean-delivered Neonates: a Randomized Controlled Trial
National Institute of Allergy and Infectious Diseases (NIAID)
Summary
Neonates delivered by scheduled Cesarean Section will be randomized to receive vaginal seeding (exposing the infant to Mother's vaginal flora) or sham. Infants will be followed for three years to examine health outcomes including microbiome development, immune development, metabolic outcomes, and any adverse events.
Description
Cesarean section (CS) delivery is a common surgical procedure intended to increase the chances of successful delivery and to protect the health of the mother and baby. Yet this intervention is overused and has been associated with higher risk of immune and metabolic disorders in the offspring. It is hypothesized that these associations are due to CS-delivered newborns not receiving the full inoculum of maternal microbes at birth. While restoring labor is not possible, restoring the microbes that colonize infants during birth through exposure to vaginal flora, is feasible, and has been shown i…

- BiologicalVaginal Seeding
A gauze containing the Mother's vaginal flora will be swabbed over the face and body of the neonate shortly after cesarean delivery.
