Statistics and Reports

The National Immunization Program monitors and reports immunization coverage among IHS American Indian and Alaska Native (AI/AN) patient populations through various tracking and reporting systems. Statistical data and reports are compiled either quarterly, annually or seasonally and for various patient and target populations (e.g., early childhood, adolescents, adults and health care workers).

Vaccine Coverage Reports

National Immunization Reporting System (NIRS)

The National Immunization Reporting System (NIRS) is a web-based reporting tool used to collect quarterly immunization data from IHS/Tribal/Urban health facilities throughout the Indian health system. NIRS was developed in partnership with the IHS Public Health Nursing Program to improve the quality and timeliness of immunization coverage data. Please see our Resources for Providers page for NIRS training materials.

Visit the National Immunization Reporting System for more information.

Quarterly Immunization Coverage Reports

Data Source: National Immunization Reporting System (NIRS)

The Indian Health Service, Tribal, and Urban Indian immunization programs report on the immunization status of American Indian and Alaska Native (AI/AN) children 3–27 months of age, 19–35 months of age and adolescents 13–17 years and adults. They also report on influenza vaccine coverage for all age groups. These reports are posted on a quarterly basis and the immunization data within the reports could vary due to delayed data entry performed after the reports are posted. For the most up-to-date and accurate immunization data, please access the Reports section in the National Reporting System (NIRS).

National Immunization Performance Measures

Government Performance and Results Act (GPRA)

The IHS immunization program tracks four GPRA immunization performance measures annually. Two measures target children: annual influenza vaccination for children six months to 17 years and a combined (4:3:1:3:3:1:4) childhood series for children 19–35 months. Two adult vaccination measures are also included: annual influenza vaccination for adults 18 years and older and an adult immunization, age-appropriate “composite” or combination measure for adults 18 years and older, which tracks age-appropriate combinations of Tdap/Td, Zoster and pneumococcal vaccines.
