Abstract
SARS coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, emerged in China in December 2019. Vaccines developed were very effective initially, however, the virus has shown remarkable evolution with multiple variants spreading globally over the last three years. Nowadays, newly emerging Omicron lineages are gaining substitutions at a fast rate, resulting in escape from neutralization by antibodies that target the Spike protein. Tools to map the impact of substitutions on the further antigenic evolution of SARS-CoV-2, such as antigenic cartography, may be helpful to update SARS-CoV-2 vaccines. In this review, we focus on the antigenic evolution of SARS-CoV-2, highlighting the impact of Spike protein substitutions individually and in combination on immune escape.
期刊介绍：
Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
