The COVID-19 Certificate, also known as a vaccine passport, is a document that verifies an individual's vaccination status against the COVID-19 virus. It may also include information about recent negative test results or recovery from the virus. This certificate is used to facilitate travel and access to certain venues or events, ensuring that individuals meet health and safety requirements. Many countries and organizations have adopted digital versions of the COVID-19 Certificate, making it easier to store and present. The certificate aims to help reduce the spread of the virus while allowing people to return to normal activities safely.
