New York State Immunization Information System (NYSIIS)

The New York State Immunization Information System (NYSIIS) participates with Eligible Professionals (EPs), Eligible Hospitals (EHs), and Critical Access Hospitals (CAHs) outside the five boroughs of New York City.

NYSIIS collects data from any EP, EH, or CAH that administers immunizations to patients. All EPs, EHs, and CAHs, are required to report immunizations administered to patients 18 years of age or younger. In order to report immunizations administered to patients age 19 or older, verbal or written consent is needed.

Note: For additional information on determining if you are required to report to an immunization registry please see Public Health FAQ #3.2 and Public Health FAQ #3.3.
