CDC Product Names reflect manufacturer trade names, but may not be identical to those registered trade names. The reason that these names vary from the manufacturers trade name is that they must reflect a unique product. Several vaccines have the same trade name for both the pediatric and the adult formulations of a vaccine.

CVX codes are codes that indicate the product used in a vaccination. MVX codes are codes that indicate the manufacturer of a vaccine. These codes are maintained by the Centers for Disease Control and Prevention, Immunization Information System Support Branch (IISSB) for use in HL7 data transmission.

The goal of the table is to support mapping of product names to CVX and MVX codes.

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