The Collaborative fosters an interconnected network of immunization data exchange partners to prioritize, develop and drive the adoption of solutions to improve immunization interoperability. Learn how the IIP Collaborative is driving action in the immunization ecosystem.
- Strengthen relationships between immunization information systems (IIS), electronic health record systems (EHRs) and other health information technology (IT), health information exchanges (HIEs), clinicians, public health and other critical partners
- Raise awareness of the issues that challenge immunization interoperability and create resources to reduce their impact
- Develop recommended guidance and solutions for prioritized issues
- Drive adoption of recommended solutions that benefit the immunization ecosystem
The IIP Collaborative, comprised of IIS, EHRs and other health IT, HIEs, clinicians, public health agencies, pharmacy and other critical partners, is addressing identified priorities for 2023 to improve immunization interoperability, information sharing and management including:
Data validation & addressing reasons for IIS rejections:
- Inconsistency in how data is entered such as dates entered in the future, birth date discrepancies, or missing fields can cause IIS to reject immunization messages; data validation prior to submission can improve acceptance.
- The Data Validation Workgroup launched in fall 2022 to develop guidance to improve successful immunization submission to IIS. Contact us at email@example.com to learn more about the workgroup’s efforts.
Regularly updating of code sets:
- Out of sync code set values (e.g., NDCs for annual flu vaccine or new vaccines) between immunization data exchange partners impedes data interoperability and can prevent patients’ vaccinations from being recorded properly within IIS.
- The Code Sets work effort launched in fall 2022 to collaborate with key partners to develop recommendations. This project seeks to develop resources to reduce:
- The level of effort and length of time required to implement new values within vaccine-related code sets used for interoperability between IIS and other health IT systems.
- The variation in understanding of code set values (e.g. use of specific v. generic, NOS codes) and code set metadata (e.g., “code is active” ) between IIS and applications used by their trading partners (e.g., EHRs)

Immunization Data from Pharmacies
Pharmacies play an important role in immunization - how can pharmacy systems leverage immunization data exchange standards and best practices to improve interoperability with IIS and maximize successful immunization submission. Submissions Prior to the Assignment of a Legal Baby Name
The first vaccination in a person’s life, hepatitis B, typically happens within 24 hours of birth. Sometimes, the legal name has not yet been assigned and when an HL7 immunization message is sent from the hospital to the IIS the name is often just a placeholder (e.g., BabyBoySmith). When the legal name is available, the hepatitis B record needs to be identified and updated to avoid duplicate records.
Triggers that Prompt Submission or Query Messages from EHRs to IIS
IIS usability could be improved through optimally defined and timed submission and query triggers. If health IT systems can exchange data with IIS at appropriate times based on specific criteria, patient data will be available to providers when needed during clinic workflows and unnecessary queries to the IIS can be avoided.
The IIP is always accepting issues as trends change and new issues emerge in the immunization data exchange ecosystem. Share Your Issue
Accessing bulk query data from IIS:
- On average, IIS receives twice as many queries as submissions. Key partner groups are unable to access the data they need in a timely manner because of disparate and/or inadequate query or bulk data protocols.
- The IIP Collaborative Bulk Query Workgroup developed a bulk query toolkit which includes best practice guidance for bulk query options. . Contact us at email@example.com to learn more and explore technical assistance opportunities.
Acknowledgments Message Handling and Error Report Guidance:
The IIP Acknowledgments Workgroup developed a guidance document and implemented pilot program to promote and validate the guidance. The workgroup convened to address variability in acknowledgment message handling among EHRs, IIS, and clinicians to improve the quality of information used for decision making.
Technical assistance opportunities are available to implement the Acknowledgments Guidance with interested partners. Email firstname.lastname@example.org to learn about technical assistance opportunities.
Common Standard for Transport of Immunization Messages:
- The IIP Executive Committee gained agreement on the unified adoption of a standard transport protocol to improve interoperability and information sharing among EHRs and IIS to support public health immunization goals. Read the Full Report Here
Multiple Match Query Solution:
- The IIP Collaborative Multiple Match Query Workgroup developed a functionalities catalog and aggregate measures for multiple matches to improve the way in which multiple patient matches, from a query to an IIS, are handled among clinicians, clinical software systems, and HIEs.
Patient Matching Brief:
- The IIP developed an educational brief to raise awareness around patient identification and matching to support immunization information sharing and management. When published, the educational brief will serve to inform:
- Current national patient matching strategies to emphasize the need for faster policy change
- Implications of the current unique health identifier federal funding ban
- Provide unbiased education as a community of experts providing insight and consensus around immunization
- Discussion supporting patient matching strategies
Interested in using IIP guidance and solutions?
The IIP offers technical assistance and support to immunization data exchange partners who would like to implement our recommendations. Contact us at email@example.com to learn more about how to engage with us to implement IIP solutions.
Approach to Prioritization
The IIP solicits immunization interoperability challenges from the broader immunization ecosystem and works with CDC to screen the issues to ensure topics are within scope not duplicative of other efforts. The IIP Executive Committee scores the issues based on criteria listed below to inform the IIP and assist the CDC Informatics and Data Analytics Branch (IDAB) to select issues to tackle.
Conduct community information gathering on each issue to:
Define and categorize the problem
Learn IIS, EHR and provider community perspectives
Identify existing efforts to address the issue
Recommend solution-based approaches to address the issue
Address additional considerations to each issue such as policy and technical barriers
Develop and apply screening and prioritization criteria for each issue to:
Assess level of impact on quality, safety and public health, impact on EHR-IIS interoperability, and information sharing
Leverage existing resources and ensure feasibility of achieving consensus on and developing a solution
Ensure impact was broad and benefited key collaborator groups
Confirm the ability to effect change through policy and other levers
Align issue topics with IIP scope, goals, and objectives
