Summary

Despite the SARS-CoV-2 virus being present worldwide, and although it is now clear that children are affected by the disease with milder symptoms than adults, many immunological questions, which are very relevant for Public Health reasons and for the organization of services, remain unsolved. The role of serology for the diagnosis of COVID-19, particularly in the pediatric age, is still very uncertain. Preliminary evidence suggests that not all children with SARS-Cov-2 infection develop antibody levels that can be detected by currently employed methods. This makes it crucial to identify other methodologies that are able to evaluate the true prevalence of prior SARS-CoV-2 infection in the pediatric population. Many other aspects of the immunological mechanisms of response to SARS-CoV-2 are also uncertain, such as the role of cellular immunity, and generally the role of immunity (cellular and antibody) in protecting against the disease in the medium and long term. Finally, questions remain open regarding cross-immunity with other previously circulating coronaviruses and their impact on the pediatric population in terms of protection against COVID-19 infection, disease development, or reinfection. This study aims to help clarify the role of serology and other immune response tests in the diagnosis of COVID-19 in the pediatric population. Specifically, it aims to assess: the prevalence of SARS-CoV-2 seroconversion cases among the pediatric population accessing the National Health System (NHS), at different moments in time and in different regions of Italy; whether cellular immunity tests can help to identify children who have had SARS-CoV-2 infection, particularly children with low antibody levels, and thus to better estimate the prevalence of prior SARS-CoV-2 infection; the prevalence of cross-reactivity with other coronaviruses; whether immunity (antibody and cellular) is protective in the medium/long term; and if there are healthy carriers, i.e. individuals who have had prior SARS-CoV-2 infection, who are asymptomatic but may harbor SARS-CoV-2 in the pharynx, with the risk of transmitting it.
