WAIIS Newsletter - July 2025

Single Sign-On (SSO)

To prepare for the implementation of a Single Sign-On (SSO) process for accessing the WA IIS, ensure that your user account has an accurate email address. Once logged into the system, click ‘Personal’ from the ‘Settings’ menu on the left of the screen. 

A reference guide and video will be available soon on the IIS Training Materials Portal. We will also be scheduling a webinar about the Single Sign-On (SSO) process later this summer. 

Polio, Unspecified Corrections

Updates to the WA IIS forecasting tool took place on February 26, 2025. WA DOH has discovered and corrected doses of ‘Polio, unspecified’ in the WA Immunization Information System (WAIIS).

The following modifications were made:

• All recorded doses of ‘Polio, unspecified’ with an administered date of 4/1/16 or later have been changed to ‘OPV bivalent’.

This ensures that the doses are correctly evaluated by the WAIIS forecaster and could result in new patients being forecasted as needing additional polio vaccine. Please vaccinate these patients with additional doses of IPV if needed to complete the series according to the Immunization Schedules | Vaccines & Immunizations | CDC. We suggest running a Coverage Rate Report to see if new patients are forecasted for IPV.

For more information on how to enter doses when IPV or OPV is not specified, refer to Polio Vaccine Documentation in the WAIIS.

Questions about this change can be directed to ImmuneNurses@doh.wa.gov.

School and Child Care Immunization Module Onboarding Pause

Due to a decrease in staffing, DOH will pause onboarding new schools and childcares to the School and Child Care Immunization Module from August 15^th though the end of December. This will enable us to support existing users with the start of the new school year and annual immunization reporting. We anticipate reopening onboarding in January 2026. We will continue to accept new Information Sharing Agreements (ISA) until August 15^th. If you haven’t signed up, now is a great time to do so. You can find the ISAs on www.doh.wa.gov/SchoolModule. Any ISAs submitted after August 15 will be processed in the order they are received starting in January. We appreciate your patience.

WA IIS Email Addresses for User Accounts

We have reached out to all users designated as a 'System Administrator' for help with updating all IIS user accounts without an email address. This is important as a 'Single Sign-On (SSO)' login process for the IIS will be implemented soon and having a valid email address for every WA IIS user account will help prevent potential issues with logins and password resets.

If you have an active WA IIS user account, check your email address by logging in and clicking 'Personal' in the 'Settings' menu on the left side of the screen. 

Please reach out to IIS.Training@doh.wa.gov if you have any questions or need further assistance.

Improving HPV Vaccination Rates

Are you looking for strategies to improve HPV vaccination rates in your clinics? We have some exciting information to share with you!

In collaboration with the Washington Chapter of American Academy of Pediatrics, the Washington State Department of Health offers the Washington Immunization Quality Improvement for Providers (WA IQIP) program. This program provides tailored support to help improve HPV vaccination rates at your clinic. Additionally, your entire team can earn 3.5 to 4 hours of FREE HPV vaccine continuing education credits (CME/CNE/CE).  This is a great way to train your team and increase vaccination rates!

To sign up, please send an email to immunizewa@doh.wa.gov. For more information about the WA IQIP program and HPV CME modules, please refer to flyer attached.

IIS Data Quality Tip of the Month

“Bad merges” occur when the system incorrectly matches two or more different individuals and merges the records. This is commonly seen with twins, siblings, and refugees.

Here are the indicators a record might be badly merged:

• A vaccine record with excessive records of the same vaccine or invalid doses.
• A record is missing in the IIS, especially if a patient has a sibling or twin with similar demographic information.
• A patient reports they did not get a vaccine that is on their record.
• A patient status is “deceased” even though they are not.

What can you do to report a bad merge? Send the IIS Data Quality team an email to iisdataquality@doh.wa.gov. We will investigate the record and let you know our findings.
