Abstract
Why children are generally less susceptible than adults to COVID-19 is unclear and has not extensively been examined longitudinally. Here the authors compare antibodies, cytokines and immune cell responses in adults and children over 6 months post-infection showing, among other things, a reduced CD4+ and CD8+ T cell response in children.
