Correlation between T cell immunity response and anti-SARS-CoV-2 antibody level in healthy participants (HPs) and kidney transplant recipients (KTRs) 20 ± 5 days after the second dose of inactivated vaccine. (A–C) The correlation between spike specific T cells frequency and anti-S1 subunit of the spike protein IgG (A), anti-receptor binding domain (RBD) IgG (B), neutralizing antibody (C) in HPs. (D) The correlation between nucleocapsid protein (NP) specific T cells frequency and anti-NP Ig in HPs. (E–G) The correlation between spike specific T cells frequency and anti-S1 IgG (E), anti-RBD IgG (F), neutralizing antibody (G) in KTRs. (H) The correlation between NP specific T cells frequency and anti-NP IgG in KTRs. SFU: Spot forming units.
