The New York State Immunization Information System
The New York State Immunization Information System (NYSIIS) is a registry of immunization information for children and youth 19 years old and younger. The system aims to establish a complete, accurate, secure, real-time immunization medical record that is easily accessible and promotes public health by fully immunizing all individuals appropriate to age and risk. Health care providers have access to the immunization information system. In addition, schools may access the immunization information system for verifying eligibility for admission.
