Abstract: A vaccination record is provided. Initially, when a patient gets a vaccine, such as a COVID-19 vaccine, an indication of the vaccine is stored in an electronic file or data structure associated with the patient called a vaccination record. The record may include information such as the type of vaccine that was administered, the date that the vaccine was administered, and an indication of the entity (e.g., clinician or healthcare practitioner that performed the vaccine). The record of the vaccine may be created in response to a billing submission by the entity. Later, the patient may use the vaccination record to provide proof to third-party verifiers that the patient in fact received the vaccine.
