Infants born to mothers who received the Pfizer-BioNTech or Moderna COVID-19 vaccine had high levels of protective antibodies, according to findings published in the American Journal of Obstetrics and Gynecology — Maternal Fetal Medicine.

“What’s new about this study is that we were able to demonstrate that the antibodies the mother builds to the vaccine cross the placenta and go to the baby, and have the potential of protecting the baby in the first days of life from getting SARS-CoV-2,” Ashley Roman, MD, director of the division of maternal fetal medicine in the department of obstetrics and gynecology at NYU Langone Health, told Healio Primary Care.
