Immunization Records Information System (IRIS)

Description: The Immunization Records Information System (IRIS) was developed for public health departments in 1993 to maintain the immunization and tuberculin testing records of all school-aged children within their jurisdictions. Immunization levels are calculated for each of the six diseases (diphtheria, tetanus, polio, measles, mumps and rubella) for which immunization is required under the Immunization of School Pupils Act (1982). In addition to mandatory vaccines, IRIS typically records all childhood vaccines, especially those that are publicly funded, including Hepatitis B, Varicella, Haemophilus, Pneumococcal and Meningococcal Conjugate C. Starting in 2004 chickenpox and meningitis is included.
