Sera neutralizing titers of 94 patients one month after 150 mg Tixagevimab and 150 mg Cilgavimab administration against authentic live viruses from the D614G historical lineage and the Omicron BA.1, BA.2 and BA.5 sublineages. Dots indicate individual samples. The serum geometric mean titers are shown with black bars and in bold characters at the top of the plot- I bars represent its 95% confidence intervals. Geometric means of individual ratio between viral strains neutralization are indicated in the upper part of the figure.
