Comparative study of SARS-CoV-2 proteins and antigenic proteins in BCG, OPV, MMR and other vaccines: evidence of possible putative protective effect

In this paper, we attempt to investigate the putative implication of BCG, OPV, MMR vaccines and nine other vaccines in the protection against COVID-19. We used a combination of bioinformatic tools to compare amino-acid sequences of the main antigenic proteins in the investigated vaccines and SARS-CoV-2 proteins and to predict the immunogenicity of similar identified patterns.
