Percent neutralization of the indicated pseudotyped viruses by VYD2311 (red) and pemivibart (blue). Dots indicate technical replicates, squares indicate mean, I bars indicate standard deviation. Five-fold serial dilutions from a maximum tested concentration of 250 μg/mL, 9 doses tested. Dashed lines indicate 50% and 90% neutralizations. The indicated inhibitory concentrations (ICs) of each antibody at 50% and 90% neutralization levels against each variant are annotated above each pair of curves.
