Vaccine Research & Development (R & D) • Vaccine: improve immunity to a particular disease • 1796: Edward Jenner’s cowpox-based vaccine against smallpox • Louis Pasteur: developed several vaccines • Anthrax vaccine (1881), • Rabies Vaccine (1885) • Ever increasing Vaccine R&D: • Cost effectiveness • Post-genomic technologies
Vaccine Publications in PubMed Vaccine publications have increased exponentially
Vaccine Databases • Government, e.g. • CDC ( http://www.cdc.gov/vaccines/) • NIH (http://www3.niaid.nih.gov/Biodefense/Research/funding.htm) • FDA( http://www.fda.gov/cber/vaccines.htm) • Organizations, e.g. • WHO (http://www.who.int/immunization_safety/en/) • The Vaccines Page( http://www.vaccines.org/) • National Network for Immunization Information:( http://www.immunizationinfo.org/VaccineInfo/index.cfm) • Academia, e.g., • HIV Vaccine Trials Network:( http://chi.ucsf.edu/vaccines/) • Commercial vaccine companies • Focus: knowledge and administration of licensed vaccines or vaccines in clinical trial
VIOLIN: Vaccine Investigation and Online Information Network • Overall goal: A vaccine research database and vaccine data analysis system • Aims: • Curate from publications: vaccines and vaccine candidates in use, clinical trials, and research • Vaccine data mining and comparison • Help vaccine design • Community-based vaccine information network • Publically available: http://www.violinet.org/

VIOLIN Statistics 275 vaccines 20 pathogens 129 pathogen genes 530 papers Data Analysis: ** Vaccine query ** Vaccine genes and antigens ** BLAST ** Vaccine target predication ** Data exchange: VIOLINML Literature tools: -- Litesearch -- Vaxpresso: NLP -- Vaxmesh: MeSH -- Vaxlert: Paper alert Literature: >24,000 abstracts >10,000 full text articles
New! Q: How to predict vaccine targets? Vaxign: Vaccine Design Program Predict vaccine protein and epitope targets Reverse vaccinology http://www.violinet.org/vaxign
What’s Missing in VIOLIN? • Lacks efficient ways to let computers answer literature mining question from >160,000 papers. • Difficult to establish vaccine-induced host immune response networks. • How to deal with it? Solution:Vaccine Ontology!
Collaborative VO Development • VO is developed as a collaborative effort: • VIOLIN and Vaccine Researchers at U of Michigan (UM) • Yongqun “Oliver” He (Interest: Brucella vaccine R&D) • Harry Mobley (Interest: E. coli vaccine R&D) • UM vaccine informatics and resource advisory committee • Infectious Disease Ontology (IDO, http://www.infectiousdiseaseontology.org/ ) • Lindsay Cowell (Duke) • Barry Smith (Buffalo) • Yongqun “Oliver” He (Michigan) • National Center for Biomedical Ontology (NCBO, http://bioontology.org/) • Barry Smith (Buffalo) • Mark Musen (Stanford) • Web site: http://www.violinet.org/vaccineontology/
Vaccine Ontology (VO) • Two forms of VO: • Core VO: general terms for all diseases • Disease-specific extensions: e.g., diseases caused by E. coli & Brucella spp. • Utilize the Basic Formal Ontology (BFO), the top-level ontology, developed by Dr. Barry Smith and his associates. • Follow OBO Foundry principles, e.g., • Developed in a collaborative effort • Use common relations that are unambiguously defined • Provide procedures for user feedback Reference: Smith B, Ashburner M, Rosse C, Bard J, Bug W, Ceusters W, Goldberg LJ, Eilbeck K, Ireland A, Mungall CJ; OBI Consortium, Leontis N, Rocca-Serra P, Ruttenberg A, Sansone SA, Scheuermann RH, Shah N, Whetzel PL, Lewis S. (2007). The OBO Foundry: coordinated evolution of ontologies to support biomedical data integration. Nat Biotechnol 25 (11): 1251-5.
Core Vaccine Ontology * * > 500 vaccine-related terms included
A Typical User Case Study Question: what are live attenuated Brucella vaccines? Should be both “Brucella vaccine” AND “live attenuated vaccine” This VO contains two: B. abortus vaccine RB51 and B. abortus vaccine strain 19 VO allows automated reasoning
What are immune responses induced by live attenuated Brucella vaccines? The question becomes: What are the immune responses induced by B. abortus vaccines RB51 and strain 19? Do they induce any immune responses defined by VO? If reported retrieve & analyze Not yet studied predict & analyze Immune Response Terms in VO
VO-based NLP Literature Mining • A VO-natural language processing (NLP) program is being developed • Retrieve VO-specified vaccine data from literature • Expand existing VO by finding more vaccine-related terms and relationships • Study vaccine-induced host immune response networks • Collaboration with NCIBI: • NCIBI: National Center for Integrative Biomedical Informatics (http://www.ncibi.org) • Drs. David States, Brian Athey, and Gil Omenn • NCIBI processes all PubMed papers by NLP
More Tasks & Questions • Assign gene names to VO terms. • Relationships with Ontologies: IDO, GO, OBI • Collaborate with OBI (Bjoern Peters, Richard Scheuermann) -- vaccine investigation, experiment … • VO application in VIOLIN DB: add instances to VO Knowledgebase • Vaccine Semantic Web?
