Arizona State Immunization Information System (ASIIS)


The Arizona State Immunization Information System (ASIIS) is an immunization registry designed to capture immunization data on individuals within the state. Providers are mandated under Arizona Revised Statute (ARS) §36-135 to report all immunizations administered to children from birth to 18 years of age to the state's health department. The registry serves as a receptacle for accommodating these reported data. In this capacity, the registry then provides a valuable tool for the management and reporting of immunization information to public health professionals, private and public healthcare providers, parents, guardians and other child care personnel.


To provide a system for the electronic capture, secure storage and confidential management of immunization data and information. To operate a system, which conforms to the minimum standards, established for registries, as recommended by the Center for Disease Control and Prevention (CDC). The data captured and stored will include all National Vaccine Advisory Committee (NVAC) approved core data elements and will enable authorized providers to retrieve and remit immunization data. The system will serve as a tool to assist public and private healthcare professionals, parents, guardians, schools and childcare personnel to effectively manage the immunization of children within the state.

Under Arizona Revised Statute (ARS) §36-135 and Arizona Administrative Code (AAC) R9-6-706 and 707, children "birth to 18" years of age are required to receive certain vaccines to enter childcare facilities and/or schools, and all healthcare professionals administering immunizations to children must report those immunization to the registry.
