    Severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) has currently caused a significant pandemic among worldwide populations. The transmission speed and the high rate of mortality caused by the disease necessitate studies for the rapid designing and effective vaccine production. The purpose of this study is to predict and design a novel multi-epitope vaccine against the SARS-CoV-2 virus using bioinformatics approaches. Coronavirus envelope proteins PROTEIN, ORF7b PROTEIN, ORF8 PROTEIN, ORF10 PROTEIN, and NSP9 PROTEIN were selected as targets for epitope mapping using IEDB and BepiPred 2.0 Servers. Also, molecular docking studies were performed to determine the candidate vaccine's affinity to TLR3 HGNC, TLR4 HGNC, MHC I, and MHC II molecules. Thirteen epitopes were selected to construct the multi-epitope vaccine. We found that the constructed peptide has valuable antigenicity, stability, and appropriate half-life. The Ramachandran plot approved the quality of the predicted model after the refinement process. Molecular docking investigations revealed that antibody-mode in the Cluspro 2.0 server showed the lowest binding energy for MHCI, MHCII, TLR3 HGNC, and TLR4 HGNC. This study confirmed that the designed vaccine has a good antigenicity and stability and could be a proper vaccine candidate against the COVID-19 MESHD infectious disease MESHD though, in vitro and in vivo experiments are necessary to complete and confirm our results.

    The worldwide outbreak of COVID-19 MESHD COVID-19 MESHD pandemic caused by SARS-CoV-2 leads to loss of mankind and global economic stability. The continuous spreading of the disease and its pathogenesis takes millions of lives of peoples and the unavailability of appropriate therapeutic strategy makes it much more severe. Toll-like receptors (TLRs) are the crucial mediators and regulators of host immunity. The role of several TLRs in immunomodulation of host by SARS-CoV-2 is recently demonstrated. However, the functionality of human intracellular TLRs including TLR3 HGNC,7,8 and 9 is still being untested for sensing of viral RNA. This study is hoped to rationalize the comparative binding and sensing of SARS-CoV-2 mRNA towards the intracellular TLRs, considering the solvent-based force-fields operational in the cytosolic aqueous microenvironment that predominantly drive these reactions. Our in-silico study on the binding of all mRNAs with the intracellular TLRs shown that the mRNA of NSP10 PROTEIN, S2, and E proteins PROTEIN of SARS-CoV-2 are potent enough to bind with TLR3 HGNC, TLR9 HGNC, and TLR7 HGNC and trigger downstream cascade reactions, and may be used as an option for validation of therapeutic option and immunomodulation against COVID-19 MESHD.

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the ongoing pandemic of coronavirus disease 2019 MESHD ( COVID-19 MESHD), a public health emergency of international concern declared by the World Health Organization (WHO). An immuno-informatics approach along with comparative genomic was applied to design a multi-epitope-based peptide vaccine against SARS-CoV-2 combining the antigenic epitopes of the S, M and E proteins PROTEIN. The tertiary structure was predicted, refined and validated using advanced bioinformatics tools. The candidate vaccine showed an average of [≥] 90.0% world population coverage for different ethnic groups. Molecular docking of the chimeric vaccine peptide with the immune receptors ( TLR3 HGNC and TLR4 HGNC) predicted efficient binding. Immune simulation predicted significant primary immune response with increased IgM and secondary immune response with high levels of both IgG1 and IgG2. It also increased the proliferation of T-helper cells and cytotoxic T-cells along with the increased INF-{gamma} and IL-2 HGNC cytokines. The codon optimization and mRNA secondary structure prediction revealed the chimera is suitable for high-level expression and cloning. Overall, the constructed recombinant chimeric vaccine candidate demonstrated significant potential and can be considered for clinical validation to fight against this global threat, COVID-19 MESHD.
