Immunization Tracking

Recording, monitoring and enforcing the vaccinations required for an employee or student population.

Reviewed June 2026 by Enterprise Health

Key facts

  • Tracks history, due/overdue status and compliance holds
  • Schedules follow CDC/ACIP and state mandates
  • Exchanges with state registries (IIS) via HL7
  • Supports titers as proof of immunity where allowed

What it means

Immunization tracking maintains each person's vaccine history, flags what is due or overdue against the right schedule, and enforces holds or restrictions until requirements are met. For health systems it covers HepB, influenza, MMR and TB; for universities it covers state-mandated student vaccines. Bidirectional exchange with state immunization registries (IIS) keeps records authoritative.

Frequently asked

What does immunization tracking do?

It maintains each person's vaccine history, flags what's due or overdue against the right schedule, and can hold or restrict status until requirements are met. It covers staff (HepB, flu, MMR, TB) and students (state-mandated vaccines).

How does it stay accurate across systems?

Through bidirectional HL7 exchange with state immunization information systems (IIS), so records reconcile with the authoritative registry and reduce the records-chasing that slows onboarding.
