A "Health Passport" is a digital or physical document that contains an individual's health information, including vaccination records, medical history, and test results. It is designed to facilitate safe travel and access to services by providing proof of health status, especially in the context of infectious diseases like COVID-19. Health Passports can be used by travelers to meet entry requirements for different countries or events. They may also help healthcare providers quickly access important medical information in emergencies. Various organizations and governments are developing their own versions of Health Passports to standardize health data sharing.
