Record of vaccine administration.

Data Element

Information from the submission form

Immunization Code
The code for the vaccine that was administered or was to be administered.


Unified Comment from CDC

  • Rename element  to Vaccine Code to align with US Core and with the other elements in the Immunizations Class.  
  • Suggest replacing the V2 element of Immunizations with this Vaccine Code element that  includes a definition and descriptive name (keep the associated terminology).  
  • Additional Use Case: Immunization elements are a major piece of public health control and mitigation. When combined with case reports to a jurisdiction or notification to CDC, it allows the jurisdiction or CDC to see where immunizations may be lacking. Immunization information may not directly provide disparity information, but it is needed together with other disparity-related data (e.g., race, ethnicity, location) to identify vaccine breakthroughs or problems with vaccination access/coverage which may also speak to broader health disparities related to general access to medical care and services. Immunization information including date of administration is collected as part of case based surveillance for Hepatitis A, Acute Hepatitis B and Perinatal Hepatitis B to understand hepatitis transmission patterns and ensure appropriate interventions are prioritized within impacted communities.  
  • Number of stakeholders who capture, access, use or exchange this data element:  All US States and DC are funded through CDC’s Division of Viral Hepatitis flagship Notice of Funding Actions to perform surveillance activities, including collection of these data for surveillance purposes.  
  • Support for healthcare aims:  Improving patient experience of care, Improving health of populations, Reducing cost of care, Improving provider experience of care  
  • Use of data element:  Extensively used in production environments  
  • Exchange of data element: CDC Message Mapping Guides (MMG) (e.g., COVID-19);
  • The Multiple Chronic Conditions eCare Plan project successfully tested this element at the Sep 2020 and Jan 2021 FHIR connectathons and has implemented it at the OHSU testing site.
  • This element is used by CMS Quality Reporting and is marked Required or MustSupport in the FHIR QI Core IG  
  • CSTE supports inclusion of this measure into USCDI v3: supports information being shared with IIS across the country – should be captured for all IZ, not just children.

Suggest renaming to Vaccine Code

The MedMorph project recommends renaming this element to Vaccine Code which aligns with the FHIR US Core element Immunization.vaccineCode. Also, will this element replace the V1 element of Immunizations?
