NCT05672654

Brief Summary

The aim of this study is to identify both the humoral immunological response through the detection of induced antibodies and the cellular immunological response through the detection of interferon gamma production by functional CD4+ and CD8+ cells in different groups of immunocompromised patients. For antibody detection, LIAISON® SARS-CoV-2 TrimericS assay (DiaSorin) will be used and for the evaluation of cellular immunity - QuantiFERON SARS-CoV-2 assay (QIAGEN).
