19 potential immunogenicity B-cell epitopes, including 2 epitopes located within the RBD region were reported using in silico analysis. 17 of them have >14 amino acids. The B-cell epitopes which had highest score in this study is the 1052-FPQSAPH-1058 located at position 1052aa of S protein. 499 T-cell epitopes bound 34 most popular HLA alleles in the Chinese population were also found. Around 30 candidate vaccine peptides in which 5 peptides located within the RBD region and 17 of them contained both B- and T-cell epitopes, were designed [111]. These vaccine candidates are theoretically able to induce either specific humoral or cellular immune against SARS-CoV-2.
