As a comparator for transplacental efficiency, we estimated the cord:mother transfer ratio of antibodies against malaria pre-erythrocytic stage antigen CSP and merozoite antigen MSP3 among SARS-CoV-2 seropositive mothers and paired cord samples (Fig. 3a).There was no difference in the mean transfer ratio between N antibodies (mean = 1.08, 95% CI 0.94–1.24) and CSP antibodies (mean = 1.35, 95% CI 1.20–1.51). The gene discussed is DNAJC5; the disease is malaria.
