Maternal and Neonatal SARS-CoV-2 Omicron Variant Neutralization after Antenatal mRNA Vaccination.

ABSTRACT: We evaluated the neutralization efficiency against SARS-CoV-2 omicron variant in maternal and cord blood sera after antenatal BNT162b2 vaccination. Neutralizing antibodies against omicron were lacking at the time of delivery after two-dose vaccination. A third booster dose was essential in building neutralizing antibody capacity against omicron among mothers and neonates.
