FDA CVX Code Vaccines Administered

$179 / year

The Centers for Disease Control and Prevention’s National Center of Immunization and Respiratory Diseases (NCIRD) developed and maintains the CVX (vaccine administered) code set. The provided dataset published on December 16th, 2015 has the most up to date values for active and inactive vaccines.


These codes should be used for immunization messages using either HL7 Version 2.3.1 or HL7 Version 2.5.1.

For each Vaccine the CVX code is mentioned with the full name of the vaccine and a short description also the current status of the vaccine is available with the update date.

The Vaccine_Status column indicates if the vaccine is currently available in the United States with the following descriptions:
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 Updated_Date column indicates the last time this particular vaccine code was updated in this dataset.
