Organizations must sign an information sharing agreement to access the Washington State Immunization Information System (IIS). This helps assure the confidentiality, privacy, and security of the system.
Technology Requirements
- A computer with Internet access is required. The system is most compatible with Microsoft Internet Explorer 11 or higher.
- Printer connection to print immunization history and reports.
Ways to Share Data with the IIS
Direct Data Entry into the IIS
Entering immunizations in the IIS can be done manually by logging into waiis.doh.wa.gov/iweb for participating providers without an active interface connection. For assistance with this process please view our IIS Training Materials Portal.
