Assessment of maternal, neonatal cord blood SARS-CoV-2 antibodies, placental transfer ratios

January 29, 2021

What The Study Did: 
Maternally derived antibodies are a key element of neonatal immunity. This study examined the association between maternal and neonatal SARS-CoV-2-specific antibody concentrations because understanding the dynamics of maternal antibody responses to SARS-CoV-2 infection during pregnancy and subsequent transplacental antibody transfer can inform neonatal management as well as maternal vaccination strategies.

Authors: 
Scott E. Hensley, Ph.D., of the University of Pennsylvania in Philadelphia, and Karen M. Puopolo, M.D., Ph.D., of the Children's Hospital of Philadelphia, are the corresponding authors.
