Since the beginning of the COVID-19 pandemic,multiple SARS-CoV-2 variants have *** some variants spread only locally,others,referred to as variants of concern,disseminated globally and became drivers of the *** SARS-CoV-2 variants harbor mutations relative to the virus circulating early in the pandemic,and mutations in the viral spike(S)protein are considered of particular relevance since the S protein mediates host cell entry and constitutes the key target of the neutralizing antibody *** a consequence,mutations in the S protein may increase SARS-CoV-2 infectivity and enable its evasion of neutralizing ***,mutations in the S protein can modulate viral transmissibility and pathogenicity.
