The Ontology of Vaccine Adverse Events (OVAE) and its usage in representing and analyzing adverse events associated with US-licensed human vaccines

Erica Marcos, Bin Zhao, Yongqun He
2013 Journal of Biomedical Semantics  
To better represent and analyze VAEs, we developed the Ontology of Vaccine Adverse Events (OVAE) as an extension of the Ontology of Adverse Events (OAE) and the Vaccine Ontology (VO).  ...  Results: Like OAE and VO, OVAE is aligned with the Basic Formal Ontology (BFO).
