A method for providing secure medical alerts includes executing, using a mobile healthcare worker application executing on a mobile healthcare worker device, a Health Level 7 (HL7) compliant protocol to retrieve medical profiles from a cloud computing server. Using the mobile healthcare worker application, a medical profile of a person (e.g., child or child's mother) is identified from the medical profiles when the mobile healthcare worker device is disconnected from the cloud computing server. The identifying includes reading, using a quick response (QR) code scanner, a QR code of an immunization document of the person, or capturing, using a biometric sensor, biometric data of the person. Using the medical profile of the person, an alert is generated indicating a medical deadline for the person on a graphical user interface of the mobile healthcare worker device when the mobile healthcare worker device is disconnected from the cloud computing server.
