Severe Acute Respiratory Syndrome-Coronavirus-2 (Sars-Cov-2) Antibody Responses In Children With Multisystem Inflammatory Syndrome In Children (Mis-C) And Mild And Severe Coronavirus Disease 2019 (Covid-19)

Severe acute respiratory syndrome-coronavirus-2 (SARSCoV-2) antibody responses in children remain poorly characterized. Here, we show that pediatric patients with multisystem inflammatory syndrome in children (MIS-C) possess higher SARS-CoV-2 spike immunoglobulin G (IgG) titers compared with those with severe coronavirus disease 2019, likely reflecting a longer time since the onset of infection in MIS-C patients.
