Vocab. CVX

CVX

The CDC Vaccine Administered (CVX), developed by the National Center for Immunization and Respiratory Diseases (NCIRD) is a coding system for vaccine preparations. The codes are used for immunization messages and it is a product of the Centers for Disease Control and Prevention (CDC). CVX includes currently more than 200 active and inactive vaccine terms. It also indicates a vaccine’s current availability and the last update time for the vaccine code. Inactive vaccine codes allow users to transmit historical immunization data.

Sources

All CVX information is obtained from the following sources:

• Centers for Disease Control and Prevention (CDC) Website
• Relationships from CVX Vaccines to CVX Vaccine Groups
• The National Library of Medicine (NLM) Website: Relationships from the CVX to the RxNorm (the RXNCONSO table)

Transformation

The procedures for transforming Concepts from the source to the OMOP Standard Vocabularies can be found on the OHDSI GitHub.
