Better Epitope Discovery, Precision Immune Engineering, and Accelerated Vaccine Design Using Immunoinformatics Tools

Area of Science:

• Computational vaccinology
• Immunoinformatics
• Bioinformatics

Background:

• Computational tools are crucial for predicting immune responses to emerging diseases, biothreats, and cancers.
• Accelerated vaccine design and clinical delivery are essential for public health preparedness.
• The iVAX toolkit has been developed over 20 years by experts in Providence, Rhode Island.

Purpose of the Study:

• To present the integrated immunoinformatic toolkit, iVAX, for computational vaccine design.
• To highlight the capabilities of iVAX in antigen selection, epitope mapping, and immunogen design.
• To showcase iVAX's application in developing vaccines for human and animal diseases, as well as biodefense.

Main Methods:

• Utilizing algorithms for scoring candidate antigens and selecting immunogenic T cell epitopes.
• Employing computational tools for re-engineering or eliminating regulatory T cell epitopes.
• Redesigning antigens to enhance immunogenicity and protective efficacy against diseases.

Main Results:

• iVAX has been applied in developing a T-cell based Q fever vaccine and novel influenza vaccines.
• Cross-conserved T cell epitopes for a malaria vaccine were identified using iVAX.
• The toolkit has been used for analyzing immune responses in clinical studies and in animal models for swine influenza A, PCV2, and African Swine Fever.

Conclusions:

• The iVAX toolkit provides a secure, internet-accessible platform for advanced vaccine design.
• Its applications demonstrate success in human and animal vaccine development and biodefense initiatives.
• iVAX is poised to aid vaccine developers in creating genome-derived, epitope-driven vaccines for future health challenges.
