Immunization Information Systems

Envision WebIZ™

Now part of InductiveHealth’s unified public health platform, WebIZ™ brings together 20+ years of immunization registry excellence with leading disease and syndromic surveillance capabilities.

As the nation’s most widely deployed immunization information system provider for state and local government public health agencies, and largest contributor to CDC’s IZGateway, WebIZ™ is designed to meet CDC standards for effective tracking and administration of immunizations across any jurisdiction.

Designed for Every Level of Immunization Management

Vaccine Program Operations

Keep vaccines safe, available, and properly managed with real-time inventory tracking, VTrckS automated federal ordering, and temperature monitoring with configurable alerts.

Immunization Registry

Document, track, and share lifetime immunization records via CDC clinical decision support, bidirectional HL7 integration with EHRs, and IZ Gateway for nationwide data exchange.

Coverage Assessment & Compliance

Measure population immunity and ensure regulatory compliance with embedded analytics dashboards, school certificate compliance, and automated federal reporting.

One Platform For All Immunization Programs

Infrastructure that scales from routine clinics to mass vaccinations

Built on Microsoft .NET and SQL Server with flexible deployment options on Azure Government Cloud for scalable managed hosting. Browser-based access from anywhere, whether it’s a clinic, mobile van, or school nurse laptop.

Highly configurable to meet jurisdiction-specific immunization requirements

Commercial off-the-shelf (COTS) platform with configurable modules for standard and special programs management, including perinatal Hepatitis B, VFC/317 coordination, and state-specific requirements.

WebIZ provides admin tools that put control in public health hands, allowing users to toggle system parameters such as adding new vaccine products through code tables when CDC approves them, or updating school certificate rules when state law changes.

Robust Analytics that can identify under-vaccinated populations before outbreaks happen

Embedded Power BI dashboards show coverage rates by ZIP code, vaccine type, age group, and provider, with no custom development required. Public health officials target interventions to specific geographic and demographic gaps, while clinic managers identify patients due this week.

Near real-time visibility with rapid dashboard updates. Vaccines administered through HL7-integrated providers appear in analytics quickly, minimizing delays for coverage assessment and outbreak response.

Live operational data and preset filters to quickly access trends and patient records. Find age groups due for particular vaccines in just a few clicks.

Community Development Model That Accelerates Immunization Program Improvements

Over 20 years serving 20+ jurisdictions means proven implementation patterns for VFC workflows, perinatal Hepatitis B tracking, and complex state school requirements.

Community development models enable one jurisdiction’s funded enhancement to become everyone’s feature in the next monthly release.

Join weekly community meetings where all jurisdictions share operational insights and vote on improvements to advance immunization systems together
