In many cases Vaccines Groups represent vaccines that vaccinate against a single disease. In a few cases they represent vaccines that vaccinate against more than one disease, but are grouped together because clinicians have thought of them as a unit.
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 dataset is to support mapping of CVX to vaccine groups.
The column formerly known as “Uncertain Formulation CVX” has been changed to “CVX for Vaccine Group”. This is the code to use for identifying the vaccine group in HL7 messages for forecasting next dose due and for other cases where vaccine group needs to be identified.
