PhIP-Seq/VirScan Coronavirus phage display assay in maternal-infant dyads

Abstract

We investigated antibody linear epitope binding and transplacental transfer using the PhIP-seq/VirScan SARS-CoV-2 Spike protein phage display array in mother-infant dyads at the time of birth. SARS-CoV-2 antibody linear epitope binding after vaccination during pregnancy showed high levels of binding in carboxy terminal of N-terminal, S1/S2 cleavage site, and S2 — with multiple immunodominant regions found in the majority of mothers and infants.
