Research Article: Characterizing HLA-A2-restricted CD8+ T-cell epitopes and immune responses to Omicron variants in SARS-CoV-2-inactivated vaccine recipients
Abstract:
Introduction: Recent surveillance has identified the emergence of the SARS-CoV-2 Omicron ariant, which exhibits the ability to evade multiple neutralizing antibodies generated by prior infection or vaccination. However, significant knowledge gaps remain regarding the CD8 T-cell immune reactivity to the Omicron variant. This study aims to evaluate the characteristics of HLA-A2-restricted CD8 T-cell epitopes from the Omicron variant and analyze epitope-specific CD8 T-cell responses to SARS-CoV-2 inactivated vaccines.
