Result: Binding level results of T29I, V367F, A706V, and A831V demonstrated that these substitutions had low binding affinity in HLA-A01:01, HLA-B07:02, and HLA-B35:01 compared to the wild type, while H49Y, Q239K, V483A, D839Y, S943P, A1078S, and P1263L substitutions still had strong binding affinity with HLA molecules.

Result: Of the other 15 Spike variants, two are in perfectly-conserved residues (V615I/F, P1263L) and two in mostly-conserved residues in highly-conserved regions (A831V, A829T/S), indicating likely-functional changes.
