Strategies for screening protective viral antigens and their applications in the development of novel vaccines

Abstract:

With the development of vaccine research and development technologies, novel vaccines have been widely used in the prevention of various infectious diseases. Due to the excellent safety, novel vaccines have unique advantages in the application of vaccines against virulent pathogens. The major premise of developing novel vaccines is to screen protective antigens. With the development of various omics research, cutting-edge bioinformatics tools for eukaryotes have been well developed, while the much simpler structure of viruses compared with eukaryotic cells corresponds to relatively simple research methods. Strategies for screening protective antigens need to combine the advantages of both bioinformatics methods and traditional molecular biology methods. In this review, the strategies for screening virus protective antigens were discussed from the perspective of host and virus, and a series of bioinformatics tools developed based on eukaryotic cells that may be used for screening protective antigens were listed. This review also summarized the cases of using protective antigens to design novel vaccines, in order to better understand the strategies for screening virus protective antigens and facilitate the research and development of novel vaccines.
