Interventions
DIAGNOSTIC_TEST

SARS-CoV-2 specific IgM and IgG detection

Detection of IgM and IgG antibodies specific to the SARS-CoV-2 antigens in the blood serum using enzyme-linked immunosorbent assay (ELISA).

DIAGNOSTIC_TEST

ELISpot: detection of the T cells specific to different SARS-CoV-2 proteins

Detection of peripheral blood T lymphocytes which are activated and secrete interferon gamma (IFNgamma) upon stimulation with peptides, covering the immunodominant sequence domains of the nucleocapsid N, membrane M, or spike glycoprotein S proteins of SARS-CoV-2 coronavirus.

DIAGNOSTIC_TEST

Flow cytometry: detection of the SARS-CoV-2 specific T-helpers and cytotoxic T lymphocytes

Detection of peripheral blood T-helpers (CD45+CD3+CD4+)\* and cytotoxic T cells (CD45+CD3+CD8+)\* which are activated and secrete IFNgamma and/or interleukin-2 (IL2) upon stimulation with mixture of peptides, covering the immunodominant sequence domains of the nucleocapsid N, membrane M, and spike glycoprotein S proteins of SARS-CoV-2 coronavirus. \* CD, cluster of differentiation
