During pregnancy early third trimester immunization against SARS‐CoV‐2 confers optimal immunity to the neonate.

Reports about SARS-CoV-2 maternal-fetal transmission 1 exist including data on the transmission of maternal antibodies to the fetus.

But there are few data concerning the neutralizing activity of the transmitted antibodies.

Among 12 delivered patients with diagnosis confirmed by nasopharyngeal RT-PCR, all other samples at delivery were negatives. All the neonates from IgG-positive mothers were also IgG positive, with no IgM. Main findings were that neonates with positive neutralization activity on cord blood had a longer delay be- 

No. Research data are not shared.
