Guernsey vaccination barcodes will automatically update

Digital vaccination codes on Covid certificates will automatically update, the States of Guernsey told the BBC.

The codes link directly into the UK's NHS Covid Pass system and are integrated into Guernsey's own Travel Tracker programme, in which residents can access online versions of their vaccine certification.

When the 30 days has expired, the code will update the next time the user logs on to use their coronavirus vaccination passport.
