US Core Immunization Profile (US Core 6.1.0)
US Core Immunization Profile is a US Core 6.1.0 profile on the FHIR R4 Immunization resource. It marks 6 elements as must-support; the rows below list each constrained element's cardinality and binding strength.

Example
pidgeon data install fhir-us-core-6.0
pidgeon conform --endpoint https://your-fhir-base/fhir --ig us-core-6.0 --ciThe conform run walks the live endpoint and grades sampled resources against the installed US Core profiles. A failed report exits non-zero; --ci also fails the run on must-support gaps (MUSTSUPPORT-*) and stub-profile fallbacks (CONFORM_STUB_PROFILE).
Validation context
- strict Profile validation grades an instance against this profile's snapshot: cardinality findings carry FHIR-PROFILE-CARDINALITY and terminology binding findings carry FHIR-PROFILE-BINDING.(FHIR-PROFILE-CARDINALITY)
- strict Under pidgeon conform --ci, a sampled resource missing one of this profile's must-support elements fails the run with a MUSTSUPPORT-<element> rule id.
- strict If the fhir-us-core-6.0 package is not installed, validation falls back to an embedded subset stub and the report is flagged CONFORM_STUB_PROFILE; under --ci that warning fails the run.(CONFORM_STUB_PROFILE)
