    For Providers

    What is an Immunization Information System?

    ImmuNet is Maryland's immunization information system (IIS). An IIS is a confidential and secure computer database designed to collect and maintain vaccination records of children and adults. Utilization of the IIS promotes cost-effective and efficient disease prevention, which leads to better health for Maryland's citizens.

    IIS have proved successful in meeting social and fiscal goals. An IIS can identify pockets of at-risk children and target resources in these areas to protect at-risk children. Moreover, IIS continue to prove their cost-effectiveness. For example, the cost of manually retrieving data for school forms without an IIS is $14.50 compared to just $3.91 to maintain a child in an IIS.

    Reasons Why ImmuNet is Necessary

    • Physicians overestimate how many of their patients are fully immunized.
    • Parents often are not aware of their child’s immunization status.
    • Due to poor record-keeping, a child may receive too many vaccinations.
    • Duplicate vaccination costs are estimated at $15 million annually.
    • Most providers don't have immunization reminder systems.
    • High risk and under-immunized populations are easily identifiable with an IIS.

    Benefits to Providers

    • Save staff time to search or replace patient vaccination records.
    • Improve healthcare delivery to your patients (capability to print reminders).
    • Access a patient’s consolidated history of immunizations received from multiple healthcare providers.
    • Assists in vaccine management and prevent costly vaccine waste by avoiding unnecessary doses.
    • Achieve reporting requirements or quality improvement measures.
    • Electronically submit vaccination data and avoid manual data entry.
