At present, The VaegenDB has collected information on 101 papers, including 161 susceptibility genes and 86 related vaccines. Notably, most of the susceptibility genes stored in the database came from peer-reviewed literature describing experiments in which at least one experimental animal model has been shown to be associated with adverse reactions. The source of the document (such as the library), the search strategy, the search procedure, and the results of each step. Its purpose is to ensure the transparency and repeatability of the research, and the relevant data is also one of the bases for judging the authenticity of the research, and it is also convenient for researchers to check and revise.
