The Vaccine Investigation and Online Information Network (VIOLIN) is a central online resource for vaccine literature, vaccine research data, and data analyses for vaccines and vaccine candidates. It focuses on vaccines developed against pathogens considered to be of high priority in public health and biological safety. It's database includes research from studies using laboratory animals as well as humans. VIOLIN also provides a new program for vaccine target prediction.
VIOLIN provides a set of programming utilities for accessing its database. Users may employ either SOAP or REST calls to retrieve entries on a specified pathogen or vaccine. All data is returned in XML format.
