Clin Infect Dis. 2022 Jun 10;74(11):2053-2056. doi: 10.1093/cid/ciab762.

Abstract

Among 9048 people infected with SARS-CoV-2 between January and May 2021 in Maryland, in regression-adjusted analysis, SARS-CoV-2 viruses carrying the spike protein mutation E484K were disproportionately prevalent among persons infected after full vaccination against COVID-19 compared with infected persons who were not fully vaccinated (aOR, 1.96; 95% CI: 1.36-2.83).

Keywords: B.1.351; COVID-19; E484K; L452R; genomic surveillance.
