We can’t unfortunately help at this point with anything relating to Covid vaccine passports or status certificates. International certification standards have not yet been agreed.
The Scottish Government is working to support the re-opening of international travel once it is safe to do so. They are working with the other UK Nations and with the World Health Organization to agree on potential future COVID certification requirements for international travel.
As part of this, they are developing a technical solution that could allow people to access their COVID vaccination status directly.
