Vaxjo : A Web-Based Vaccine Adjuvant Database and Its Application for Analysis of Vaccine Adjuvants and Their Uses in Vaccine Development

Abstract EN

Vaccine adjuvants are compounds that enhance host immune responses to co-administered antigens in vaccines.

Vaxjo is a web-based central database and analysis system that curates, stores, and analyzes vaccine adjuvants and their usages in vaccine development.

Basic information of a vaccine adjuvant stored in Vaxjo includes adjuvant name, components, structure, appearance, storage, preparation, function, safety, and vaccines that use this adjuvant.

Reliable references are curated and cited.

Bioinformatics scripts are developed and used to link vaccine adjuvants to different adjuvanted vaccines stored in the general VIOLIN vaccine database.

Presently, 103 vaccine adjuvants have been curated in Vaxjo.

Among these adjuvants, 98 have been used in 384 vaccines stored in VIOLIN against over 81 pathogens, cancers, or allergies.

All these vaccine adjuvants are categorized and analyzed based on adjuvant types, pathogens used, and vaccine types.

As a use case study of vaccine adjuvants in infectious disease vaccines, the adjuvants used in Brucella vaccines are specifically analyzed.

A user-friendly web query and visualization interface is developed for interactive vaccine adjuvant search.

To support data exchange, the information of vaccine adjuvants is stored in the Vaccine Ontology (VO) in the Web Ontology Language (OWL) format.
