Abstract:
The Delta pandemic wave saw increased maternal morbidity and mortality compared to prior viral strains. COVID-19 vaccination in pregnancy elicits detectable levels of neutralizing antibodies to SARS-CoV-2 wild type and SARS-CoV-2 Delta variants in both maternal and neonatal samples at delivery. Our results demonstrate the effectiveness of vaccination which confers an immunological response against newer, and potentially more dangerous, viral variants.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
