ACE2 binding inhibition to SARS-CoV-2 spike proteins by the sera of immunized macaques, related to Figure 3E
The neutralizing activity of each serum to inhibit ACE2 binding to S from the variant under monitoring B.1.640.2 Omicron BA.2.12.1 or Omicron BA.1 and BA.2 subvariants that contain the indicated additional mutation is represented as percent inhibition relative to no-serum controls. pi, post-immunization. B/HPIV3/S-6P-immunized animals are represented in blue, and B/HPIV3-immunized animals are represented in green. Each animal is represented by a unique symbol.
