IIS: Current HL7 Standard Code Set
CVX -- Vaccines Administered

The CDC's National Center of Immunization and Respiratory Diseases (NCIRD) developed and maintains the CVX (vaccine administered) code set. The table below has the most up to date values. It includes both active and inactive vaccines available in the US. CVX codes for inactive vaccines allow transmission of historical immunization records. When a MVX (manufacturer) code is paired with a CVX (vaccine administered) code, the specific trade named vaccine may be indicated. These codes should be used for immunization messages using either HL7 Version 2.3.1 or HL7 Version 2.5.1. The version of the CVX code set for certification can be found on the archive page.

The Status column indicates if the vaccine is currently available in the United States.

Active: A currently available administrable vaccine
Inactive: An administrable vaccine formulation that is no longer available for patient administration, but can be found in historical patient records.
OR A historical record of a vaccine administered where the exact formulation is unknown
Pending: A vaccine that is expected to become active in the future
Non-US: A vaccine that available outside the US only
Never Active: A vaccine that was never available and is not in the pipeline of new vaccines

The Last Updated column indicates the last time this particular vaccine code was updated in this table.

Questions regarding this table should be directed to the IIS Technical Assistance Team(or use mailing address).
