IIS Recommended Core Data Elements

IIS core data elements facilitate record exchange between IISs. Each IIS includes a method to receive and store all of the required core data elements, so when an IIS receives a record from one system and subsequently transfers it to another, no required core data elements will be lost in the process. The CDC endorsed data elements represent the data elements needed by an IIS to record patient demographics and vaccination events to meet the IIS Functional Standards v4.0.
