Pennsylvania Statewide Immunization Information System

Managed by the Pennsylvania Department of Health, the Pennsylvania Statewide Immunization Information System (PA-SIIS) is a statewide immunization registry that collects vaccination history information. It was developed to achieve complete and timely immunization for all people, particularly in the age group most at risk, birth through two years of age.

The PA-SIIS helps to serve the public health goal of preventing the spread of vaccine preventable diseases. A major barrier to reaching this goal is the continuing difficulty of keeping immunization records accurate and up to date. The PA-SIIS addresses this problem by capturing immunization information from health care providers and storing this information in one central location. If a patient receives immunizations from more than one health care provider, the PA-SIIS consolidates the immunization information from all providers to create a complete and current record. This assists health care providers to age-appropriately immunize all patients in their care.
