Vaccination is the best way to prevent the spread of emerging or reemerging infectious disease. Current research for vaccine development is mainly focused on recombinant-, subunit-, and peptide-based vaccine. At this point, immunoinformatics has been proven as a powerful method for identification of potential vaccine candidates, by analyzing immunodominat B- and T-cell epitopes. This method can reduce the time and cost of experiment to a great extent, by reducing the number of vaccine candidates for experimental testing for their efficacy. This chapter describes the use of immunoinformatics and molecular docking methods to screen potential vaccine candidates by taking Leptospira as a model.

The Zika virus (ZIKV), an arbovirus within the Flavivirus genus, is associated with severe neurological complications, including Guillain-Barré syndrome in affected individuals and microcephaly in infants born to infected mothers. With no approved vaccines or antiviral treatments available, there is an urgent need for effective therapeutic options. This study aimed to identify new natural compounds with inhibitory potential against the NS2B-NS3 protease (PDB ID: 5LC0), an essential enzyme in viral replication.

Peptidyl prolyl cis/trans isomerases (PPIases), a ubiquitously distributed superfamily of enzymes, associated with signal transduction, trafficking, assembly, biofilm formation, stress tolerance, cell cycle regulation, gene expression and tissue regeneration, is a key regulator of metabolic disorders and microbial virulence. This review assumes an integrative approach, to provide a holistic overview of the structural and functional diversity of PPIases, examining their conformational dynamics, cellular distribution, and physiological significance. We explore their intricate involvement in cellular processes and virulence modulation in both eukaryotic and prokaryotic systems.

COVID-19 infections continue due to accessibility barriers to vaccines and the emergence of SARS-CoV-2 variants. An effective, safe, accessible, and broad-spectrum vaccine is still needed to control the disease. We developed a multivalent protein subunit vaccine comprising antigens designed from a non-N-glycosylated region of the receptor-binding domain of the spike protein of SARS-CoV-2.

Infectious Bursal Disease is a highly contagious, immunosuppressive viral disease of young chicks caused by the Infectious Bursal Disease Virus (IBDV). The study was carried out at the National Veterinary Institute (NVI) of Ethiopia to evaluate the competence of the DF-1 cell culture adapted vaccine strain of IBDV as a vaccine candidate. DF-1 cells at passage 27 confluent monolayer was infected with 1 ml of LC-75 vaccine strain virus by adsorption method and recorded as passage 1 (P).
