Middle East respiratory syndrome (MERS), also called camel flu, is a viral respiratory infection caused by the MERS-coronavirus (MERS-CoV). . Genomic sequencing, DNA manipulation, vaccine development—for all the cutting-edge scientific tools at our disposal, we have had a glaring inability to fully grasp the dangers emanating from this strange and bulbous family and to determine its animal origins. The current study aimed to cover the diversity of SARS-CoV-2 strains reported from all over the world and to design a broad-spectrum multi-epitope vaccine using an immunoinformatics approach. CoVs are enveloped, positive-stranded RNA viruses with a nucleocapsid (capsid with nucleic acid) reported size of 300-400 nm under the electron microscope [].All CoVs are pleomorphic viruses that usually produce 80-160 nm and 27-32 kb positive polarity of crown-shaped peplomers []. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a member of the beta-coronaviridae family, which contains Middle-East respiratory syndrome (MERS)-CoV and SARS-CoV. Once inside, the coronavirus enlists the infected cell to produce the parts it needs: RNA and proteins. What is more, the MRP pseudo-sequence supertree showed detailed evolutionary relationship of SARS-CoV-2, with nine sub-branches identified from Clade A to Clade I in Fig. Kiyoshi Takahase Segundo / Alamy. These viruses are relatively large, consisting of 26 to 32 . Porcine epidemic diarrhea virus (PEDV) (family Coronaviridae family, genus alphacoronavirus) has an enveloped, single-stranded, positive-sense RNA genome of ≈28 kb ().The 5′ two thirds of the genome contains 2 large open reading frames (ORFs), 1a and 1b, that encode 2 nonstructural polyproteins, pp1a and pp1b, that direct genome replication and transcription. .
