Systems, methods, and devices for verification of an immunization status of an individual and for secure data portability are provided. A system for verifying an immunization status of an individual includes a verification device, a vault computing device, and an immunization record database server. The verification device includes a web terminal configured to send an immunization status request including identifying data about the individual. The vault computing device receives the immunization status request and generates and sends an immunization record request including an insurance plan number corresponding to the individual. The immunization record database server has access to an immunization record database and retrieves immunization record data from the immunization record database using the insurance plan number and sends the immunization record data to the vault computing device. The vault computing device generates immunization status data representing the immunization status of the individual from the immunization record data and sends the immunization status data to the verification device. The verification device receives the immunization status data via the web terminal and displays the immunization status data in a user interface.
