As explored below and summarized in Table 1, studies that investigated if it also occurs for anti-SARS-CoV-2 antibodies found that pregnant women who had COVID-19 active infection or received the COVID-19 vaccine developed anti-SARS-CoV-2 IgM, IgG, and IgA, and these antibodies were transferred to the fetus via placental transport or breastfeeding (48, 51, 53, 70–73). This evidence concerns the gene CD40LG and COVID-19.
