Bioinformatics analysis was used to create a multi-epitope mRNA vaccine targeting S. agalactiae by targeting pathogenic proteins. The study, published on Nature.com, focused on exploiting specific proteins of the bacteria to develop an effective vaccine. By utilizing bioinformatics tools, researchers were able to identify key epitopes that could trigger an immune response against S. agalactiae. This approach holds promise for developing a vaccine that can effectively combat this pathogen.
