Novel Vaccine Development for Fish Culture Based on the Multiepitope Concept

For the past several decades, aquaculture all around the world have been retarded by various disease outbreaks caused by many pathogens including parasites, bacteria, and viruses. Apart from being harmful to human health, the emerging diseases also dramatically affect the farm animals such as livestock and aquatic animals. To cope with this problem, one of the effective prophylactic measures is the application of vaccine. However, the traditional vaccines still have some limitations and several drawbacks; thus there is a need for the development of novel advanced vaccine such as chimeric multiepitope vaccine. Based on the current understanding of genomics and immunoproteomics together with the present bioinformatics tools, the researchers can identify the potential targeted epitopes being recognizable by the immune cells. Additionally, another critical point that should be considered for designing the chimeric multiepitope vaccine is the exposure of all those epitopes to the host organism. Thus, selecting an appropriate linker and joining each identified epitope in a suitable site can create the ideal protein structure protruding all the selected epitopes on its surface. Herein, our study would provide the fundamental platform to develop the multiepitope B-cell vaccine for the prevention and control of the aquatic animal disease starting with the epitope prediction until in vivo testing the multiepitope vaccine efficacy.
