About USIIS

The Utah Statewide Immunization Information System (USIIS) is a free, confidential, web-based information system that contains immunization histories for Utah residents of all ages. USIIS consolidates immunizations from multiple providers into one centralized record.

Only authorized users, such as health care providers, pharmacies, schools, licensed childcare programs, and public programs have access to USIIS. USIIS complies with HIPAA and state law to protect patient privacy. All providers and users must sign confidentiality agreements before they are given access to USIIS.

USIIS is populated with birth records of infants (through a link with electronic birth records) and immunization records from public and private healthcare providers
