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.

Looking for Your Patient's Vaccination Records?
Maryland providers who are authorized ImmuNet users but do not have access to ImmuNet are encouraged to sign up for access to ImmuNet here. Out-of-State providers may request records with this Record Request form. Note that requestors must self-identify by checking the acknowledgement statement (under penalty of perjury) before submitting the form.
Patients can access their own vaccination records directly via the MyIR portal here. MDH provides these MyIR brochures for printing and distribution, or complete the Brochure Request form (here) to have brochures mailed to you.
Maryland is an Opt-Out state. Per §18-109(d), patients may refuse to permit authorized users of ImmuNet access to their records.
If your patients do not wish to share their or their child’s vaccination record with all providers, including yourself, in ImmuNet, they must complete an Opt-Out form here. Hard copies (here) can be downloaded for printing and distribution.
If they change their minds and wish to allow their/their child’s records made available to their/their child’s provider(s) again, they must complete a Rescind Opt-Out from here. Hard copies (here) can be downloaded for printing and distribution.
Clients who have opted out in ImmuNet do not wish their records to be made available to authorized Immunet users. Providers may request those immunization records with a Release of Opted-Out Record form here.
Note: If you or your patients complete a hard copy of any form, please mail or fax the hard copy form. Do not email the completed form as it places you or your patients at risk for exposing sensitive information. Emailed forms will not be accepted unless you or your patients are able to use a secure email service.
