Longitudinal Antibody Responses to SARS-CoV-2 Infection in Children: Impact of Age, Vaccines and Symptoms.

The majority of children experience severe acute respiratory syndrome coronavirus-2 infection as a mild infection. In this longitudinal single-center study of children infected early in the pandemic and managed as outpatients, we assess the impact of age, vaccination, recurrent infection and initial symptoms on severe acute respiratory syndrome coronavirus-2-specific antibody responses over time.
