ABSTRACT The genome‐based surveillance of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) in the past nearly 5 years since its emergence has refreshed our understanding virus evolution, especially on convergent co‐evolution with host. SARS‐CoV‐2 evolution been characterized by sets mutations that affect functional properties altering infectivity, virulence, transmissibility, and interactions host immunity. This poses a huge challenge to global prevention control measures based drug treatment vaccine application. As one key evasion strategies response immune profile human population, there are overwhelming amounts evidence for reduced antibody neutralization variants. Additionally, data also suggest levels CD4 + CD8 T‐cell responses against variants or sub‐variants decrease populations, although non‐negligible cross‐T‐cell maintained. Herein, from perspectives structural immunology, we outline characteristics mechanisms T cell SARS‐CoV variants/sub‐variants. molecular bases impact escaping interaction epitopes receptors adaptive immunity, is, major histocompatibility complex (MHC), receptor (TCR), summarized discussed, knowledge which will widen this pandemic‐threatening assist preparedness Pathogen X future.
