DataSheet_1_Differences in systemic and mucosal SARS-CoV-2 antibody prevalence in a prospective cohort of Dutch children.docx

Background As SARS-CoV-2 will likely continue to circulate, low-impact methods become more relevant to monitor antibody-mediated immunity. Saliva sampling could provide a non-invasive method with reduced impact on children. Studies reporting on the differences between systemic and mucosal humoral immunity to SARS-CoV-2 are inconsistent in adults and scarce in children. These differences may be further unraveled by exploring associations to demographic and clinical variables. Methods To evaluate the use of saliva antibody assays, we performed a cross-sectional cohort study by collecting serum a... Mehr ...
