WA State Immunization Information System (WAIIS) Forecast Implementation

The WA State Immunization Information System (WAIIS) forecast was updated on February 26, 2025. This new and improved forecasting tool will allow our WAIIS technology vendor to efficiently make corrections and updates to forecasting recommendations. Please check out the Vaccination Summary & Forecast Quick Reference Guide and watch this short video for more details regarding this update.

Please send an email to immunenurses@doh.wa.gov if you have any questions or concerns. We appreciate all of you for letting us know of potential bugs so we can log a ticket with our WAIIS vendor.

Thank you for all your efforts to ensure that immunizations are complete and accurate in WAIIS! We really appreciate all you do to promote vaccinations in our state!

ISA Renewals

The DOH provider enrollment team is working to renew the Information Sharing Agreements (ISAs) for organizations participating in the WAIIS. Please check your records to ensure your ISAs are up to date as these agreements expire every 3 years.  You may lose connectivity to the IIS if no response is received during our review and cleanup of IIS data.

If you are not up to date, click here to renew your agreement or contact pchoiisa@doh.wa.gov for any additional questions.
