Washington State Immunization Information System

The Washington State Immunization Information System (IIS) (PDF) is a lifetime registry that keeps track of immunization records for people of all ages. The system is a secure, web-based tool for healthcare providers and schools. The IIS connects people who receive, administer, record, and order vaccines in Washington.

NEW! The IIS is now integrated with Secure Access Washington

General IIS Information

DOH works closely with our IIS third-party technology vendor to address and fix any technical problems that arise within the registry. We do our best to monitor these issues closely and communicate temporary problems to our stakeholders and IIS users. To drive down program costs, WA participates in a consortium with other states that use the same system. As a result, some upgrades and project priorities are subject to approval from the entire consortium. For comments, questions or concerns about the forecasting, functionality, or the user experience of the WAIIS, please contact the IIS Help Desk at 1-800-325-5599 or WAIISHelpDesk@doh.wa.gov.
