Vaccination for the prevention and treatment of leishmaniasis can be the most effective way to combat this disease. In this study, we designed a novel multi-epitope vaccine against <jats:italic>Leishmania major<\/jats:italic> (<jats:italic>L<\/jats:italic>. <jats:italic>major<\/jats:italic>) using immunoinformatics tools to assess its efficacy <jats:italic>in silico<\/jats:italic>. Sequences of Leish-F1 protein (TSA, Leif, and LMSTI1) of <jats:italic>L<\/jats:italic>. <jats:italic>major<\/jats:italic> were taken from GenBank. The helper T (Th) and cytotoxic T (Tc) epitopes of the protein were predicted. The final multi-epitope consisted of 18 CTL epitopes joined by AAY linker. There were also nine HTL epitopes in the structure of the vaccine construct, joined by GPGPG linker. The profilin adjuvant (the toll-like receptor 11 agonist) was also added into the construct by AAY Linker. There were 613 residues in the structure of the vaccine construct. The multi-epitope vaccine candidate was stable and non-allergic. The data obtained from the binding of final multi-epitope vaccine-TLR11 residues (band lengths and weighted scores) unveiled the ligand and the receptor high score of binding affinity. Moreover, <jats:italic>in silico<\/jats:italic> assessment of the vaccine construct cloning achieved its suitable expression in <jats:italic>E<\/jats:italic>. <jats:italic>coli<\/jats:italic> host. Based on these results, the current multi-epitope vaccine prevents <jats:italic>L<\/jats:italic>. <jats:italic>major<\/jats:italic> infection <jats:italic>in silico<\/jats:italic>, while further
