本综述整理了COVID-19的发病、SARS-CoV-2基因组结构、导致全球多波感染的新病毒谱系的出现以及疫苗的标准和快速通道开发等方面的信息。随着时间的推移,不断演变的SARS-CoV-2已经获得了扩大的突变景观。刺突蛋白突变(诊断、治疗和疫苗的主要目标)的功能特征揭示了病毒变异谱系中传播、发病机制和免疫逃逸潜力的增加。发生的突变还导致大量病毒中和逃逸到目前使用的疫苗、单克隆、多克隆和恢复期抗体中。目前的情况表明,需要开发精确的下一代疫苗和治疗方法,以更保守的基因组病毒区域为目标,提供充分的保护。
This review collates information on the onset of COVID-19, SARS-CoV-2 genome architecture, emergence of novel viral lineages that drove multiple waves of infection around the world and standard and fast track development of vaccines. With the passage of time, the continuously evolving SARS-CoV-2 has acquired an expanded mutational landscape. The functional characterization of spike protein mutations, the primary target of diagnostics, therapeutics and vaccines has revealed increased transmission, pathogenesis and immune escape potential in the variant lineages of the virus. The incurred mutations have also resulted in substantial viral neutralization escape to vaccines, monoclonal, polyclonal and convalescent antibodies presently in use. The present situation suggests the need for development of precise next-generation vaccines and therapeutics by targeting the more conservative genomic viral regions for providing adequate protection.
