About VIIS

Immunization Registries (IIS)

What is VIIS?

VIIS is the acronym for Virginia Immunization Information System, an immunization registry for the state that contains immunization data of persons of all ages
VIIS is a free, web-based computerized medical record system for immunization data that documents all immunizations a person has received from all medical sources into one definitive, accurate record.
VIIS is an opt-in registry, but parents/guardians may ask to opt-out of VIIS
The information about immunization history will be available to all participating heath care providers and school nurses

What is the purpose of VIIS?

The Centers for Disease Control and Prevention (CDC) have set a goal that at least 95% of children are adequately immunized against vaccine-preventable diseases.
An incomplete immunization record is one of the greatest obstacles to this goal.
A complete and accurate immunization record will eliminate the unnecessary duplication of immunizations that now occurs in 21% of children

What are the benefits of VIIS?

To consolidate all immunizations given to a patient by multi-providers
To improve the health of Virginia’s children against vaccine-preventable diseases
To prevent under/over immunization of children by providing access to a complete and accurate immunization record
To provide updated recommendations for immunization scheduling using an algorithm to review the client’s immunization history and recommend age-appropriate vaccines
To reduce staff time needed to obtain complete immunization history of clients
To produce an official immunization record that serves as ‘Certification of Immunization’ on the school entry form
To generate parental reminder notices for their child’s due vaccines
To recall children who received invalid vaccines due to spacing or age
To allow for recalls in the event of a manufacturing error
To allow for statewide analysis of immunization patterns to prevent vaccine-preventable diseases
To provide a mechanism for tracking the distribution of immunizations or prophylactic medications in the event of a public health emergency

What are the goals of VIIS?

To increase and sustain high immunization coverage rates in the state
To ensure that each child receives recommended and required immunizations
To ensure that immunization services are documented accurately
To eliminate missed opportunities by having parents/guardians recalled/reminded of due vaccinations
To assess accurately the immunization status of each child
To identify the geographic pockets-of-need within Virginia
