Dear Editor,Although coronavirus disease 2019(COVID-19)is no longer deemed a“Public Health Emergency of International Concern”,the global transmission dynamics of SARS-CoV-2 have shifted due to vaccination,emergency of virus variants,and pre-existing coronavirus immunity.1–3 It remains unclear how cross-reactive and pre-existing humoral immunity might impact the effectiveness of vaccines and antibodies against new viral mutations.4,5 This study seeks to elucidate the cross-reactivity of coronavirus antibodies induced by previously unencountered Omicron BA.5/BF.7 variants in the breakthrough infection(BTI)population.
