We established two cohorts of pregnant women in whom serological assessment of both IgG and IgM antibody response to SARS-CoV-2 was assessed. In total, between both cohorts, for IgM anti SARS-CoV-2 antibodies were detected in 28 women and IgG antibodies were detected in 15 women. Umbilical samples were obtained from seventy-eight of these women during our study period. Nine women returned for longitudinal assessment of antibody response on days 101-122 post baseline testing.
