SARS-CoV-2-challenged NHP serum samples show neutralization against SARS-CoV-2 variants: Six (6) serum samples from SARS-CoV-2-challenged NHPs (N = 2 from each species: rhesus macaques (1M16756, 1M16757), cynomolgus monkeys (2M16748, 2F16755), African green monkeys (3M16763, 3F16765)) were subjected to PBNA using the pseudoviruses for 614D and variants as described in Section 2. The PBNI₅₀ for each animal is shown on the Y-axis. Crosshatch-filled bars show the average PBNI₅₀ from two independent experiments for 614D, plain bars show the PBNI₅₀ for the B.1.351 SA variant, diamond-filled bars show the PBNI₅₀ for the B.1.1.7 UK variant.
