Early SARS-CoV-2 reinfections within 60 days highlight the need to consider antigenic variations together with duration of immunity in defining retesting policies

2022-04-07

Abstract excerpt

The emergence of the SARS-CoV-2 Omicron variant, characterized by a significant antigenic diversity compared to the previous Delta variant, had led to a decrease in antibody efficacy in both convalescent and vaccinees’ sera resulting in high number of reinfections and breakthrough cases worldwide. However, to date, reinfections are defined by the ECDC as two positive tests ≥60 days apart, influencing retesting pol...
