A vaccination certificate is an official document that confirms an individual has received a specific vaccine. It typically includes details such as the person's name, the type of vaccine administered, the date of vaccination, and the issuing authority. This certificate serves as proof of immunization against certain diseases, such as COVID-19 or measles. Vaccination certificates are often required for travel, entry into certain venues, or participation in events. They help public health officials track vaccination rates and ensure community safety. Many countries have adopted digital versions of these certificates for easier access and verification.
