What Is a Vaccine Certificate?

A vaccine certificate is an official document that provides proof of vaccination against specific diseases. In today's interconnected world, these certificates have become increasingly important for international travel, employment, and public health management. The document typically includes details such as the recipient's personal information, the type of vaccine administered, dates of vaccination, and the issuing authority.

The Historical Evolution of Vaccine Certificates

The concept of vaccine certificates isn't new. The practice dates back to the early 19th century when countries began requiring proof of smallpox vaccination for travelers. This system laid the groundwork for modern vaccination documentation and international health regulations.
