HealthTech NHS Children's Immunisation Digital Register — NHS Region

NHS NIIS Integration and Immunisation Records

NHS Immunisation Information System (NIIS): national immunisation record system replacing regional CHIS.

NIIS FHIR R4 API

Immunization resource (vaccine code, dose number, date administered, location, practitioner), Patient resource (NHS number via PDS), and Encounter resource (immunisation appointment).

UK Immunisation Schedule

• PHE/UKHSA immunisation schedule (8 weeks — 6-in-1, Men B, Rotavirus
• 12 weeks — 6-in-1 second dose
• 16 weeks — 6-in-1 third dose
• 1 year — MMR, Men B booster, Men C... through to 14 years — Td/IPV booster).

Platform

• age-appropriate immunisation status dashboard (what is due, what is overdue, what is complete) for each child on the register.
• Call-

Recall and Defaulter Management

• NHS childhood immunisation call-recall: invitation letter to parents when child due for immunisation.
• GOV.

UK Notify

automated invitation letters, SMS reminders (4 weeks after invitation if no appointment booked), and second reminder (8 weeks if still not booked).

Defaulter management

child who has missed an immunisation schedule point — automated alert to health visitor for follow-up.

Cohort management

annual birth cohort pulled from NHS PDS (all children born in the region) → immunisation schedule populated automatically.

Traveller and homeless families

enhanced follow-up workflow (health visitor personal contact).

Clinical safety hazard

child incorrectly recorded as up-to-date when immunisation is overdue — child not invited for missed vaccinations — preventable disease.

Mitigation

• 1NHS PDS synchronisation (weekly PDS pull — picks up moved children and new registrations),
• 2immunisation status calculated in real time from administered vaccine records (not a stored flag that can become stale),
• 3monthly data quality audit (random 200-record sample reviewed by clinical governance — administered vaccines reconciled against NIIS records).

NIIS data

• every vaccine administered at a GP practice or immunisation clinic submits to NIIS — platform reads NIIS as source of truth.
• ICO AADC and Children's

Health Data

ICO Age Appropriate Design Code (AADC): digital services likely to be accessed by children.

Parent portal

parents can view their child's immunisation record.

AADC compliance

• 1parent/guardian authentication via NHS Login (verified parental relationship),
• 2data minimisation — parent sees only their child's immunisation record (not siblings until all verified),
• 3health data is Article 9 special category — explicit consent basis for parent viewing own child's health record,
• 4child can access their own record from age 13 (Gillick competence — GDPR data subject rights).
