Neutralization of SARS-CoV-2 variants by RBD-chAb combinations. A Neutralization assays testing RBD-chAb-15 or -28 combined with -45 or -51 against SARS-CoV-2 variant pseudoviruses. Each assay was performed in triplicate; data points represent the mean. Data for each RBD-chAb are representative of at least two independent neutralization experiments. B Neutralizing RBD-chAb-15 or -28 combined with -45 or -51 inhibits SARS-CoV-2 variants, Alpha, Gamma and Delta; infection was assessed by PRNT. The PRNT₅₀ value was calculated with Prism software. Each assay was performed in triplicate, and all data points are shown, along with the mean ± SD
