Population

The preferred spoken or written language of the patient receiving the vaccine, recorded at the time of immunization. Used in immunization systems to ensure vaccine information statements, consent forms, and post-vaccination instructions are provided in the patient's primary language to support informed consent compliance.

The patient's family surname recorded at the time of vaccine administration. Used in immunization registries and EHR systems for patient identity matching, record lookup, and demographic verification to ensure accurate attribution of vaccination events to the correct patient record.

The patient's full official name as documented on government-issued identification at the time of vaccine administration. Used in immunization registries for identity verification, regulatory reporting, and ensuring vaccination records are correctly attributed to the legally recognized patient identity.

A hierarchical classification value assigned to a vaccination record in EHR and public health registry systems. Denotes the tier of a vaccine series (e.g., primary, booster, catch-up) to support dose-counting logic, CVX code mapping, and immunization schedule compliance tracking.

The state or national professional license identifier of the clinician or healthcare provider who administered the vaccine. Captured in immunization records to document accountability, meet regulatory requirements, and support audit trails verifying that vaccinations were performed by appropriately credentialed personnel.

The patient's legal marital status recorded at the time of vaccine administration. Captured as part of the demographic profile in immunization registries and EHR systems to support complete patient records, population health reporting, and eligibility determinations for certain public health vaccination programs.

The enterprise master patient index identifier linked to a vaccination administration record, enabling consistent patient identification across disparate healthcare systems. Used to reconcile immunization records from multiple facilities, registries, or health information exchanges into a unified longitudinal patient immunization history.

The upper threshold value defined for a specific vaccine-related measurement or dosing parameter, such as maximum allowable dose quantity or maximum patient age for eligibility. Used in immunization clinical decision support rules to enforce safety limits and ensure compliance with vaccine administration guidelines.

The facility-assigned medical record number of the patient who received the vaccine, linking the immunization event to their complete medical record. Used in EHR and immunization registry systems to retrieve patient history, reconcile vaccination records, and support continuity of care across clinical encounters.

The patient's middle name or initial recorded at the time of vaccine administration. Used in immunization registries and EHR systems as a supplementary demographic identifier to disambiguate patients with similar first and last names and improve accuracy of patient record matching across healthcare systems.

The lower threshold value defined for a specific vaccine-related measurement or dosing parameter, such as minimum patient age or minimum interval between doses. Used in immunization clinical decision support systems to enforce eligibility rules and ensure vaccinations are not administered before the clinically or regulatory approved minimum criteria are met.

The mobile phone number of the patient or guardian recorded at the time of vaccine administration. Used in immunization systems to support appointment reminders, recall notifications for subsequent doses, vaccination record distribution, and public health outreach communications related to immunization schedules.

The username or system identifier of the user or process that last updated a vaccination administration record. Used in immunization audit trails to maintain data integrity, support regulatory compliance, and provide accountability tracking for any changes made to immunization documentation after initial entry.

The timestamp recording the most recent update to a vaccination record in EHR, IIS, and claims adjudication systems. Critical for change data capture (CDC) pipelines, audit trail compliance, and reconciling discrepancies between source systems during immunization data integration.

The precise date and timestamp when a vaccination administration record was last updated in the system. Used in immunization data management to maintain audit trails, detect data changes, support synchronization between immunization registries and source systems, and ensure record integrity for regulatory and clinical reporting.

The human-readable display label for a vaccine in EHR, pharmacy, and immunization registry systems. Typically maps to CVX codes (CDC vaccine terminology) or NDC codes, enabling standardized vaccine identification across HL7 FHIR Immunization resources and HEDIS measure reporting.

Free-text or structured annotation attached to a vaccination record in EHR and immunization registry systems. Captures clinician observations, patient reactions, administration deviations, or refusal reasons, and maps to HL7 FHIR Immunization.note elements for interoperability and audit purposes.

Unique numeric identifier assigned to a vaccination record within EHR or immunization registry systems such as IIS or VXU HL7 messages. Used by data engineers to deduplicate immunization events and link records across CDC, state registry, and payer claims datasets.

The date when a patient's adverse reaction, illness, or relevant clinical condition began, documented in relation to a vaccine administration event. Used in immunization safety surveillance and adverse event reporting systems such as VAERS to assess the temporal relationship between vaccination and subsequent health outcomes.

Records the patient's blood oxygen saturation level (SpO2) measured at the time of vaccine administration. Captured as a pre- or post-vaccination vital sign to assess patient stability and identify contraindications or adverse reactions requiring clinical intervention.
