A vaccine passport is a document or digital certificate that verifies an individual's vaccination status against certain diseases, such as COVID-19. It is often used to facilitate travel, entry to events, or access to specific venues where proof of vaccination is required. These passports can be issued by governments, health organizations, or private companies and typically include information like the type of vaccine received, the date of vaccination, and personal identification details. The goal of a vaccine passport is to help ensure public safety while allowing individuals to participate in activities that may pose a higher risk of disease transmission.
