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.
