Abstract

As the global COVID-19 pandemic progresses, it is paramount to gain knowledge on adaptive immunity to SARS-CoV-2 in children to define immune correlates of protection upon immunization or infection. We analyzed anti-SARS-CoV-2 antibodies and their neutralizing activity (PRNT) in 66 COVID-19-infected children at 7 (±2) days after symptom onset. Individuals with specific humoral responses presented faster virus clearance and lower viral load associated with a reduced in vitro infectivity. We demonstrated that the frequencies of SARS-CoV-2-specific CD4+CD40L+ T cells and Spike-specific B cells were associated with the anti-SARS-CoV-2 antibodies and the magnitude of neutralizing activity. The plasma proteome confirmed the association between cellular and humoral SARS-CoV-2 immunity, and PRNT+ patients show higher viral signal transduction molecules (SLAMF1, CD244, CLEC4G). This work sheds lights on cellular and humoral anti-SARS-CoV-2 responses in children, which may drive future vaccination trial endpoints and quarantine measures policies. [Display omitted] • Antibody neutralization is inversely associated with SARS-CoV-2 in nasopharyngeal swabs • Antigen-specific B cells positively associate with anti-SARS-CoV-2 humoral immunity • SARS-CoV-2 neutralizing antibodies are present in patients with higher specific T cells • Antigen-specific B and T cells are features of SARS-CoV-2 immunity in children Cotugno et al. show that neutralizing antibodies affect SARS-CoV-2 viral load in infected children. Antigen-specific B and T cells are positively associated with virus neutralization. This information provides a basis for defining SARS-CoV-2 adaptive responses in children. [ABSTRACT FROM AUTHOR]

Abstract

Data on features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children and adolescents are scarce. We report preliminary results of an Italian multicentre study comprising 168 laboratory-confirmed paediatric cases (median: 2.3 years, range: 1 day–17.7 years, 55.9% males), of which 67.9% were hospitalised and 19.6% had comorbidities. Fever was the most common symptom, gastrointestinal manifestations were frequent; two children required intensive care, five had seizures, 49 received experimental treatments and all recovered.
