Abstract: An immunization web portal may identify whether a patient is eligible to receive vaccines for a specified vaccine-preventable disease. The patient's eligibility may be identified by comparing biographical data and medical characteristics for the patient to a set of eligibility requirements according to state and federal law. If the patient is eligible, the immunization web portal may display indications of several vaccines corresponding to the vaccine-preventable disease, and a user such as a pharmacist or technician may select one of the vaccines so that the selected vaccine may be administered to the patient.
