The official URL for this profile is:

http://hl7.org/fhir/us/core/StructureDefinition/us-core-immunization

This profile sets minimum expectations for the Immunization resource to record, fetch and search immunization history associated with a patient. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios for the US Core-Core Immunization profile:

  • Query for immunizations belonging to a Patient
  • Record or update immunizations belonging to a Patient

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition]) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each Immunization must have:

  1. a status*
  2. a vaccine code that identifies the kind of vaccine administered
  3. a date the vaccine was administered
  4. a patient

Each Immunization must support:

  1. a statusReason if the vaccine wasn’t given
  2. a flag to indicate whether the vaccine was reported by someone other than the person who administered the vaccine.

Profile specific implementation guidance:

  • Use the status code: not-done to represent that an immunization was not given.
  • Based upon the ONC U.S. Core Data for Interoperability (USCDI) v1 requirements, CVX vaccine codes are required and the NDC vaccine codes SHOULD be supported as a translation. CDC provides the CDC National Drug Code (NDC) Directory – Vaccine NDC Linker Table to assist implementers. The example Immunization-imm-1 illustrates using both the CVX and NDC codes based upon this table.
    • Note that the CVX code system contains some concepts that are procedures, medications, or substances rather than immunizations. Implementers should not use these non-vaccine-related CVX codes.

Quick Start


Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile’s information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

  • The syntax used to describe the interactions is described here.
  • See the General Guidance section for additional rules and expectations when a server requires status parameters.
  • See the General Guidance section for additional guidance on searching for multiple patients.

Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported:

  1. SHALL support searching for all immunizations for a patient using the patient search parameter:

    GET [base]/Immunization?patient={Type/}[id]

    Example:

    1. GET [base]/Immunization?patient=1137192

    Implementation Notes: Fetches a bundle of all Immunization resources for the specified patient (how to search by reference)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

  1. SHOULD support searching using the combination of the patient and date search parameters:
    • including support for these date comparators: gt,lt,ge,le
    • including optional support for composite AND search on date (e.g.date=[date]&date=[date]]&...)

    GET [base]/Immunization?patient={Type/}[id]&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}

    Example:

    1. GET [base]/Immunization?patient=1137192&date=ge2019-01-14T00:00:00Z

    Implementation Notes: Fetches a bundle of all Immunization resources for the specified patient and date (how to search by date and how to search by reference)

  2. SHOULD support searching using the combination of the patient and status search parameters:

    GET [base]/Immunization?patient={Type/}[id]&status={system|}[code]

    Example:

    1. GET [base]/Immunization?patient=1137192&status=completed

    Implementation Notes: Fetches a bundle of all Immunization resources for the specified patient and status (how to search by reference and how to search by date)
