What if a providers historical records do not contain all of the data elements available in NYSIIS?
• Some provider’s existing records of historical immunization information contain most, but not all, of the required data fields. For example, providers may not have mother’s maiden name, vaccine lot numbers, or manufacturer for historical immunizations. In these instances, reporting of all available historical information should occur when all of the required data fields are submitted for the current immunization. Incomplete information for immunizations administered prior to January 1, 2008 will be accepted. If missing information is not available to the provider, the Department may ask the provider to attest to this fact as part of future quality assurance activities.
