New York State Immunization Information System (NYSIIS)

The New York State Department of Health's (NYSDOH) Bureau of Immunization is committed to promoting the health of New York State children by reducing and/or eliminating the number of vaccine preventable diseases that affect the State's children.

As part of this effort, the New York State legislature passed the Immunization Registry Law which, as of January 1, 2008, requires health care providers to report all immunizations administered to persons less than 19 years of age, along with the person's immunization histories, to the New York State Department of Health using the New York State Immunization Information System (NYSIIS).

The goal of the new immunization information system is 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.

An immunization information system provides numerous benefits to all those involved in the health care of children, contributing to a higher immunization rate and a healthier population.

  • Providers have access to consolidated and accurate immunization records of their patients, receive clinical decision support in complying with an increasingly complex vaccination schedule and can use an efficient tool to manage their vaccine inventory.
  • Parents and caregivers get reminders when an immunization has been missed. Up-to-date information on a child's vaccination history helps to prevent over-immunization.
  • Schools will be able to save time in complying with safety and health regulations.
  • Public health systems use the information to control vaccine preventable diseases.

NYSIIS, in conjunction with the legislative mandate, strongly supports the NYSDOH Bureau of Immunization's objective to meet the Center for Disease Control's (CDC) Healthy People goal of 95% of children less than six years of age enrolled in an IIS with two or more shots.
