Replication Data for: DHHS-CDC Vaccine Data Code Sets for September 17th, 2025 (9/17/2025)

Vaccine Code Data Sets are released seasonally by the Centers for Disease Control and Prevention (CDC), to document the current manufacturer and date of a given set of vaccines. Some vaccines remain relatively unchanged year to year, but some vaccines like influenza and COVID-19, change seasonally and yearly. Code Data Sets refer to an identification number of the vaccines available, based on the date of their release and the manufacturer. This information can be found in the “buisness_rules.pdf” file of this archive, as well as here: https://www.cdc.gov/iis/downloads/business-rules.pdf . The code sets themselves are encapsulated in the Excel files in this archive (where CVX is the time period and MVX is the manufacturer). CPT is the Current Procedural Terminology and is the usage information for the vaccine.
