In a similar study of the preliminary analysis of COVID-19 vaccine targets [1] the investigators tried to use the spike protein and nucleo-capsid protein sequences of SARS-COV that are homologous to some extant with SARS-COV-2 proteins to determine multiple different epitopes for Vaccine prediction, but in our study out of five two proteins namely ORF-3a and ORF-7a specific to SARS-COV-2 were found to be putative T-cell epitope determinants that create useful information; these proteins are also important for viral replication [41].
