Maternal Immunization Against SARS-CoV-2 and Infant Immunity Persistence in a Brazilian Cohort
From January 2021 to March 2022, we studied antibody transfer and persistence in infants of SARS-CoV-2-infected or vaccinated pregnant women in Brazil. Third-trimester vaccination increased maternal anti-S immunoglobulin G, correlating with cord and infant levels at 6 months. Neutralizing antibody were detected only in vaccinated mothers and cord blood, persisting in only 2 infants at 6 months.
