Predicting epitopes for vaccine development using bioinformatics tools.

Epitope-based DNA vaccine development is one application of bioinformatics or studies, that is, computational methods, including mathematical, chemical, and biological approaches, which are widely used in drug development. Many studies have been conducted to analyze the efficacy, safety, toxicity effects, and interactions of drugs. In the vaccine design process, studies are performed to predict epitopes that could trigger T-cell and B-cell reactions that would produce both cellular and humoral immune responses. Immunoinformatics is the branch of bioinformatics used to study the relationship between immune responses and predicted epitopes. Progress in immunoinformatics has been rapid and has led to the development of a variety of tools that are used for the prediction of epitopes recognized by B cells or T cells as well as the antigenic responses. However, the approach to vaccine design is still relatively new; thus, this review is aimed at increasing understanding of the importance of studies in the design of vaccines and thereby facilitating future research in this field.
