    Snippet: The epitope designing was conducted only with the COVID 19 spike glycoprotein sequence and structure. From the sequence analysis, 10 different locations were found which also showed similarity with SARS CoV and SARS COVID 2 spike glycoprotein in protein BLAST (Figure 4) . Also the motif positions within the spike glycoprotein monomer were represented in figure 4 . Epitopes 1, 4 and 5 were not represented in COVID 19 spike glycoproteins, as they w.....
    Document: The epitope designing was conducted only with the COVID 19 spike glycoprotein sequence and structure. From the sequence analysis, 10 different locations were found which also showed similarity with SARS CoV and SARS COVID 2 spike glycoprotein in protein BLAST (Figure 4) . Also the motif positions within the spike glycoprotein monomer were represented in figure 4 . Epitopes 1, 4 and 5 were not represented in COVID 19 spike glycoproteins, as they were found to be embedded within the virus envelop. Among the others, motifs 2, 3, 6 and 7 were found at the interior location of spike glycoprotein monomer but motifs 8, 9 and 10 were found at the surface of the structure, which could be used as the immunological targets for the proper diagnosis and treatment of COVID 19.

Specific mutant structure has been designed and tested to be resistant to conformational change after ACE2 binding and protease cleavage at the S1/S2 site [34] . This may be indicative to searching suitable epitope which may remain unhindered from pre-to post-fusion state transition.
