Population

Middle name or initial of the patient recorded on a vaccination encounter to support accurate identity matching in immunization registries and health information exchanges. Reduces patient misidentification when common first and last name combinations exist within the same geographic registry.

Lower boundary value defined for a vaccination-related clinical parameter, such as the minimum patient age for vaccine eligibility, minimum dose quantity, or minimum interval required between doses in a series. Applied in clinical decision support to ensure immunization schedules meet safety and efficacy standards.

Mobile phone number associated with the patient receiving a vaccination, used for appointment reminders, immunization series completion notifications, and vaccine recall communications. Supports outreach programs in public health immunization campaigns and patient engagement workflows within care management systems.

Username or system identifier of the user who last updated a vaccination record. Maintained as part of the audit trail for immunization data integrity, supporting compliance with record amendment policies and traceability requirements in clinical data governance and regulatory review processes.

Timestamp recording when a vaccination record was most recently updated in the clinical or immunization registry system. Used in audit logging, data reconciliation, and change tracking workflows to ensure the accuracy and integrity of immunization histories submitted to public health authorities.

Timestamp recording when a vaccination record was last updated in the clinical system. Used for audit trails, data synchronization, and identifying the most recent changes to immunization records across EHR and immunization registry integrations.

The human-readable name of the administered vaccine, such as Influenza, MMR, or COVID-19. Used in clinical documentation, patient immunization histories, and immunization registry reporting to identify the specific vaccine product given to the patient.

Free-text clinical annotation associated with a vaccination event, capturing details such as patient reactions, administration observations, refusal reasons, or special circumstances not captured in structured fields within the immunization record.

A unique numeric or alphanumeric identifier assigned to a specific vaccination record. Used to reference, track, and reconcile immunization events across clinical systems, immunization registries, and public health reporting platforms.

The date on which symptoms or an adverse reaction began following vaccine administration. Used in pharmacovigilance, VAERS reporting, and clinical follow-up workflows to document and assess post-vaccination adverse events and their temporal relationship to immunization.

The patient's blood oxygen saturation level recorded at the time of vaccine administration. Captured as a pre- or post-vaccination vital sign to document baseline health status or monitor for immediate adverse respiratory reactions during the observation period.

The dollar amount reimbursed or paid for a vaccination service, recorded in claims or billing systems. Used to track immunization-related financial transactions, reconcile payments from insurers or public health programs, and support cost reporting.

The date on which payment was received or processed for a vaccination service. Used in billing and claims workflows to reconcile immunization reimbursements, track payment cycles, and support accounts receivable reporting for vaccine administration services.

A reference linking a vaccination record to its parent entity, such as a parent vaccine series, encounter, or hierarchical data structure. Used in immunization data models to represent series relationships, multi-dose schedules, or organizational groupings of vaccine records.

A percentage value associated with a vaccination record, such as population immunization coverage rates, reimbursement percentage, or dose completion rates within a series. Used in public health analytics, quality measure reporting, and financial calculations for immunization programs.

The defined time interval associated with a vaccination program, coverage window, or dose schedule. Used to track immunization eligibility windows, vaccine series intervals, reporting periods for immunization compliance, and public health program timeframes.

The telephone contact number associated with the facility, provider, or patient record linked to a vaccination event. Used for follow-up communications, adverse event reporting, immunization reminder outreach, and coordination with immunization registries or public health agencies.

The documented immunization schedule or clinical plan outlining which vaccines are recommended or planned for a patient. Used in preventive care workflows to guide administration timing, track completion of multi-dose series, and align with CDC or ACIP immunization guidelines.

The insurance policy identifier associated with coverage for a vaccination service. Used in claims billing and adjudication workflows to link immunization records to the correct health plan, enabling proper reimbursement and coverage verification for administered vaccines.

The preferred or standardized display name for a vaccine, used when multiple naming conventions exist. Ensures consistent presentation of vaccine names across patient-facing materials, clinical summaries, immunization registries, and interoperability exchanges such as HL7 or FHIR interfaces.
