Children & Hoosiers Immunization Registry Program (CHIRP)

CHIRP

The Children and Hoosier Immunization Registry Program (CHIRP) is a secure web-based application that is administered by the Indiana Department of Health, designed to permanently store a person’s immunization records in an electronic format. Healthcare providers can use the registry to review vaccination records for their patients and record all newly administered vaccinations.

Access CHIRP
MyVaxIndiana

MyVaxIndiana allows Hoosiers to directly access immunization records from any computer through the use of a personal identification number (PIN). Local health departments and healthcare providers will be the primary access point to obtain PINs. The PINs can be used by individuals to log in to a secure website and check immunization history for themselves and their children as it is recorded in the Indiana Children and Hoosiers Immunization Registry Program (CHIRP). Only registered CHIRP providers will be able to generate PINs.

Immunization Registry Requirements

The state of Indiana mandates the use of the registry for certain providers. For more information about the CHIRP requirements, please contact the CHIRP Help Desk at 888-227-4439 or chirp@isdh.in.gov.

  • Medical Providers

    Indiana Code 16-38-5-2 went into effect on July 1, 2015. This provision mandates all medical providers in the state of Indiana to submit complete vaccination records to the state CHIRP registry system within seven business days. This new legislation covers all vaccines that are administered to individuals under 19 years of age.

    CHIRP can accept an import with an HL7-type message from an Electronic Health Record (EHR). Providers have the option to send this information electronically; however, the message must comply with the national standards for HL7 messaging. The current adopted version types for an HL7 message are 2.3.1 or 2.5.1.

  • Medical Providers Enrolled in a Publicly Funded Vaccination Program

    Medical providers enrolled in the Vaccines for Children (VFC) and Adult Immunization Programs are required to follow Policy 15: Immunization Information System Requirements. This policy requires providers to meet the requirements of IC 16-38-5 and to use the Vaccine Ordering Management System (VOMS) component of CHIRP.

  • Pharmacies

    Pharmacies that administer immunizations for patients of any age are required by IC 25-26-13-31.2 to record vaccine administration information in the CHIRP registry within seven business days.

  • Schools

    All schools that are accredited under the Indiana Department of Education use CHIRP to review and update student immunization records. The schools must also use the registry to report vaccination coverage levels among students attending each individual school. Schools must have parent permission under the Family Educational Rights & Privacy Act (FERPA) prior to entering any immunization records into the registry.

  • Data Exclusion Request

    An individual, parent or guardian may request that immunization data be excluded from the registry at any time. An individual, parent or guardian may also request to permanently opt-out or be excluded from Indiana’s state immunization registry. To submit for one or more exclusions, please complete and submit.
