Welcome to the Tennessee Immunization Information System (TennIIS)

About TennIIS

TennIIS is a statewide immunization information system (IIS) managed by the Tennessee Department of Health. TennIIS is a free, secure, and easy-to-use online registry of vaccinations received by Tennessee residents.

TennIIS can be utilized by healthcare providers, pharmacists, schools, and childcare administration to access and update vaccination records. Through TennIIS, authorized users can access the Immunization Certificate Validation Tool (ICVT) to print validated Official Immunization Certificates for children in Tennessee.

TennIIS can also be used to retrieve Patient Immunization Record Reports, Reminder/Recall Reports, Coverage Rate Reports, and Immunization Forecasting Reports.

For eligible professionals and hospitals, participation in Electronic Data Exchange with TennIIS is a valid public health reporting measure under the federal Centers for Medicare and Medicaid Services (CMS) electronic health record incentive programs. These programs include Meaningful Use (MU) and Merit Based Incentive Payment System (MIPS).

TennIIS also hosts the online Vaccine Ordering Management System (VOMS) for the federal Vaccines for Children (VFC) Program.

Electronic Data Exchange and Meaningful Use/MIPS Registration

What is Electronic Data Exchange?

Any practice that administers vaccinations can exchange data electronically between its Electronic Health Record (EHR) system and TennIIS. Electronic data exchange is an efficient way to add or retrieve vaccination records in TennIIS, and can eliminate the need for entering data separately into both TennIIS and the EHR.

If you have any questions about electronic data exchange, contact

Meaningful Use (MU), Merit Based Incentive Payment System (MIPS) and Public Health Reporting in Accordance with CMS Incentive Programs
