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. Immunization information is entered into the system by health care providers who agree to participate for the benefit of their patients. The PA-SIIS is a web-based registry that is currently available at no cost to health care providers and their staff for both data entry and inquiry.

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 record assists health care providers in age-appropriately immunizing all patients in their care.

If you are interested in participating in the PA-SIIS, you only need to complete the Provider Interest Form available on the PA-SIIS web site or by clicking on the attachment below. After you have completed the Provider Interest Form, a PA-SIIS staff member will contact you to schedule a meeting and establish an implementation date.
