SARS-CoV-2 spike (S) and nucleocapsid (N) antibody reactivity in NYS infants with single or repeat specimens between November 2019 and November 2021. Percentage of infants with single or repeat specimens born S+ or N+ SARS-CoV-2 antibody reactive (S+N+) (left y-axis, circles or squares, respectively) by month of birth. Percentage of infants with repeat specimens born SARS-CoV-2 antibody non-reactive who became S+ or N+ antibody reactive in a post-birth specimen (S–N– to S+ or N+) (right y-axis, triangles) by midpoint month between initial and last specimen.
