Washington State Immunization Information System

The Washington State Immunization Information System (IIS) (PDF) is a lifetime registry that keeps track of immunization records for people of all ages. The system is a secure, web-based tool for healthcare providers and schools. The IIS connects people who receive, administer, record, and order vaccines in Washington.
