What is an Immunization Information System?
Immunization Information Systems (IIS) are confidential,
population-based, public health information systems that collect data on all
immunization given in a geographic area. Put simply, IIS securely store
comprehensive vaccination histories throughout a person’s lifetime- gone are
the days of carrying around that paper record!- but they do so much more than
that! See the “What are the benefits of using an IIS?” section below to
learn more. In Nevada, the IIS is known as Nevada WebIZ. Our
IIS connects people with comprehensive information, improving Nevada’s ability
to protect its communities from vaccine-preventable diseases.
What is Nevada WebIZ?
Nevada WebIZ (pronounced “web-eye-zee”) has been in use
since 2003, and reporting became mandatory in 2007 (for children) and 2009 (for
adults). As of January 2020, the system contained over 4.1 million
patient records, which include over 44 million vaccinations. Over 1,600
public and private authorized organizations in over 3,300 locations, including
medical practices, hospitals, local health authorities, school districts, and
child care facilities, have access to view, add, and/or update immunization
information for Nevada’s communities. The Nevada State Immunization
Program continuously works to advance and improve the quality of Nevada WebIZ’s
data and functionality.
What are the benefits of using an IIS?
IIS connect people with information they need to make
informed decisions about vaccination, including giving the right dose at the
right time, reminding patients to return when a dose is coming due, showing
public health authorities the populations most vulnerable to
vaccine-preventable disease, exchanging data electronically in real-time with
doctors’ medical record systems, and supporting the important activities of a
state’s immunization program. The Centers for Disease Control and
and the American Immunization Registry Association (AIRA) work together to provide
guidance and best practices to Immunization Programs nationwide to ensure IIS
continue to meet the needs of our communities.
Nevada WebIZ is a core piece of the Nevada State
Immunization Program and its various partners. It is used to support
vaccine ordering and accountability for the Vaccines For Children Program,
conduct vaccination quality improvement activities, provide to insurance
companies information for their Healthcare Effectiveness Data and Information
Set (HEDIS), and to identify and address disparities in vaccination coverage.
