Schematic diagram of the PP19128R vaccine construction strategy and secondary structure. (A) The PP19128R vaccine was constructed based on TLR2 agonist PorB, pan HLA DR-binding epitope PADRE, 19 HTL epitopes, 12 CTL epitopes, 8 B-cell epitopes, and TLR-4 agonist RS-09. (B) The amino acid sequence of the PP19128R vaccine, with different elements indicated by different colors. (C) The coil, helix, and strand secondary structures in the amino acid sequence of the PP19128R vaccine are shown in gray, pink, and yellow, respectively.
