How are immunizations sent to the state registry? Is this interface performed automatically, or does the staff need to select a certain option when charting?

Transmission depends on the public health agency. Some states utilize Public Health Information Network Messaging System (PHIN-MS), File Trasnfer Protocol (FTP) or batch transmissions and others that require real-time updates – all via an HL7 v2.5.1 message. For immunization reporting, the software is designed with logic that automatically generates a message in the background so charting of immunizations is all that the staff need to do to initiate. There is setup in the software at the item level to ensure administration charting includes lot number and expiration date.
