Neutralization sensitivity of WT and WT-BA.1S2 to RBD sera: (A) The neutralization curves are shown for WT and WT-BA.1S2 PVs as a function of serum dilution. (B) The neutralization titers against WT and WT.BA.1S2 for mouse sera (n = 34) elicited by WT-RBD immunogen. The GMT titer is shown above each column. (C) The neutralization titers against BA.1 and WT-BA.1S1 PVs are shown for mouse sera (n = 10) elicited by BA.1-RBD immunogen. (D) Same as in C but with mouse sera elicited by WT-RBD (n = 10). The median titers are shown above each column. Two independent assays were done to confirm reproducibility.
