- Abstract
Maternal and cord blood sera were collected from 20 parturients who received the BNT162b2 vaccine. All women and infants were positive for anti S- and anti-receptor binding domain antibody–specific immunoglobulin G. Cord blood antibody concentrations were correlated to maternal levels and to time since vaccination. Antenatal severe acute respiratory syndrome coronavirus 2 vaccination may provide maternal and neonatal protection.
