about the South Dakota Immunization Information System (SDIIS)

What is SDIIS?

The South Dakota Immunization Information System (SDIIS is a computer software system that will establish a network of public and private health care providers and allow them to share immunization records when needed.   Each Provider will create a local database of clients, which will be used to track immunization status and remind parents when shots are due.

Why is sharing immunization records so important to health care providers?

Immunization records are an important part of your child’s medical record.  Standard immunization practices recommend that health care providers have a written record of your child’s previous immunizations to continue the immunization series.  If the parent or guardian cannot produce a record, the whole series must be started over again.  Because many of us do remember to bring out immunization record to the physician for every visit, immunizations may be either unnecessarily administered or missed.  SDIIS will allow your physician to have access to your child’s existing immunization record, thus allowing your child to stay on schedule.

Who will have access to my child’s immunization record?

As written in South Dakota Codified Law, a patient’s immunization record may be shared among health care providers, schools, federal and state health agencies, licensed family day cares, and child welfare agencies.   (Many of these entities already have access to immunization records and require records for entry/participation.)  Anyone who fails to protect the confidentiality of the data in this system is guilty of a Class 1 misdemeanor.

What information will be shared among health care providers?

Your child’s name, sex, date of birth, social security number (if available), and immunization record will be shared.  Your address and phone number will not be shared.

What are the benefits of having my child’s record in this system?

If your child’s records are part of the system, your health care provider will be able to send you reminders of when your child’s next shots are due.  Also, if you go to a different provider and forget your child’s immunization record, that provider will be able to use the system to locate your child’s record.  This will help keep your child on schedule with the appropriate immunizations.  SDIIS will provide a complete immunization record for your child that will be readily available to you to give the agencies who require immunization status of their attendees, such as Head Start, licensed daycare’s, and schools.

If I choose to let my child’s immunization record be a part of the system, will I still have to bring a copy of my child’s immunization record when I visit my doctor?

Although not required, it is good practice to always bring a written copy of your child’s immunization record when you visit your health care provider.

How do I (opt out) of the system?

If you are not interested in allowing your child’s immunization record to be shared among health care providers, please fill out the waiver provided to you by your health care provider.  This waiver represents the “lock” that will be placed on your child’s record, making the immunization record inaccessible to other health care providers and the state Department of Health.

If I opt out of this system at this clinic, what will happen if I go to a different clinic next time?

If your child goes to a different provider for immunizations and you have previously opted out of SDIIS, that provider will not have access to your child’s immunization record through SDIIS.  You will be responsible for giving that provider a copy of your child’s immunization record.

I rarely hear about vaccine-preventable diseases occurring, so why does my child even need immunizations?

Because of vaccinations, the incidence of vaccine-preventable disease has been reduced significantly.  However, some are still quite prevalent, even epidemic, in other parts of the world.  Travelers can unknowingly bring these diseases into the United States where they can quickly spread through population.  At the same time, the relatively few cases we currently have in the United States could quickly become tens of hundreds of thousands of cases without the protection we get from vaccines.

We should still be vaccinated, then for two reasons.  The first is to protect ourselves.  Even if we think our chances of getting any of these diseases are small; the diseases still exist and can still infect anyone who is not protect.  The second reason to get vaccinated is to protect those around us.  A small number of people cannot be vaccinated (because of severe allergies to vaccine components, for example). And a small percentage of people don’t respond to vaccine.  These people are susceptible to disease, and their only hope of protection is that people around them are immune and cannot pass diseases along to them.


Instructions to the Provider on Locking a Patient’s Immunization Record


  • Start the ADIOS-IIS Clinic Module and open the patient record.
  • Select the General Information page by clicking on its tab.
  • Move to the Record Locking field; select Locked from the field’s drop-down list.
  • Save the patient record.

The patient record now has a ‘locked’ status.  The information for that patient will not be shared with the central database, or any other facility.
