Immunization Action Plan (IAP) Program

The Norwalk Health Department's Immunization Action Plan (IAP) Program works with medical clinics and physician offices to ensure that all area children receive age appropriate immunizations by their second birthday. The program also provides education and develops initiatives to promote recommended vaccinations for older children and adults.

In addition to providing immunization services, IAP nurses act as the state representatives for the Connecticut Immunization Registry Tracking System (CIRTS) - a state computer program that requires physicians to report all childhood vaccines.
