Immunization records

Identifies individual immunisation / vaccination records - immunisation history statements, vaccination records and certificates, register extracts and vaccine administration entries - when the phrase sits with populated patient identifiers and vaccine administration fields. Health information under applicable data protection regulations.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium: enforce tiers need a populated patient identifier; 85 also needs a vaccine administration field and a named vaccine. Immunisation schedules, clinic flyers and public health campaigns carry the phrases but no patient field, so they stay at 65.

Known false positives

Medical terminology in health education materials, research publications, clinical guidelines, or public health documents without patient-specific data. Mitigation: Require corroborative evidence keywords confirming patient context. Look for co-occurrence with patient identifiers such as medical record numbers or dates of birth.
General wellness and fitness content using medical vocabulary without constituting protected health information. Mitigation: Layer with patient identifier patterns or healthcare-specific document structure detection to distinguish clinical records from general health content.
