The Indiana State Department of Health (ISDH) maintains an Immunization Information
System known as CHIRP (Children and Hoosier’s Immunization Registry Program). The
purpose of CHIRP is to collect, forecast, manage, and share vaccine data to registered medical
providers in Indiana. A provider may include private medical facilities, local health
departments, hospitals, schools, and pharmacies. The program is run under the Indiana Code
16-38-5 which allows for providers and their designees to access data from CHIRP. In
addition an individual also may access their personal or their dependents vaccine record
from either the registered CHIRP provider or directly from the Indiana State Department of
Health.

As an update to the existing process, ISDH has created the MyVaxIndiana Immunization
Portal which enables a person to access a vaccine record from any computer. To begin this
process a registered CHIRP provider will create a patient ID number (PIN) which will grant a
person specific patient access to the record they have requested. A parent or guardian could
request a PIN to view their dependents immunization history, or any individual could do the
same for their own record. They then have a number of options as to how their data can be
viewed and saved. This includes an option to print and save the Official Immunization
Record, download the record into a file format that may be compatible with their Personal
Health Record system (PHR), or have it faxed or mailed to them.
