I want to find any instances of Influenza virus vaccine administration within the i2b2 database, with a specificity scale of 0 and a total item occurrence of 1, using the panel number 1 and a panel timing of ANY, with the invert value set to 0. The item is located under the hierarchy of medications, immunologic agents, viral vaccines, and influenza virus vaccine, and has an accuracy scale of 100.
