Wild-type-specific and Omicron BA.1-specific ACE2 displacement function following three-dose COVID-19 vaccination.

Panel a: same as Fig. 1a, but for ACE2 displacement activity in serum, a surrogate measure of virus neutralization, where results are reported in terms of % ACE2 displacement. Panel b: same data as panel a, but where ACE2% displacement activities are plotted longitudinally by participant (PWH in orange, CTRL in blue). The legend is the same as for Fig. 1b.
