Brief Summary

Coronavirus 2019 (COVID-19) infection is associated with higher morbidity and mortality in adult patients on dialysis, and kidney transplant recipients (KTRs). Although children had lower morbidity and mortality, KTRs are more vulnerable than healthy children. It has already known that the general immune responses to vaccines, which are currently in practice (attenuated, conjugated, or recombinant) were lower than healthy controls in children and adolescents on dialysis and with a kidney transplantation. Uremic milieu and immunosuppressive drugs are the factors causing impaired immune response in this group of patients. The new mRNA vaccine technology is used worldwide including children and adolescents during the pandemic. Studies have demonstrated lower immune response to new SARS-CoV-2 mRNA vaccine in adult KTRs. However, there is limited data about vaccine-induced immune response in children and adolescent with renal replacement therapy. The aim of this study was to assess immune response to SARS-CoV-2 mRNA BNT162b2 and its clinical and laboratory correlates in children and adolescent KTRs. Humoral immune response was assessed by anti-SARS-CoV-2 immunoglobulin G (Anti-S IgG) and its clinical correlate neutralizing antibody (nAb). Cellular immune response was assessed with SARS-CoV-2 specific Interferon ɣ release assay (IGRA).
