A Downing Street source told the paper: ‘We are just not in a place where we have set out what this is going to look like yet.’
It comes as Virgin Atlantic announced it would trial vaccine passports.
Customers on flights to Barbados from April 16 will be invited to use the Travel Pass app to verify they meet the Caribbean island’s entry requirements for pre-departure coronavirus testing.
Future versions of the app – developed by airline trade body the International Air Transport Association – will also include coronavirus vaccine records.
A number of other airlines are also using the app, including British Airways, Singapore Airlines, Emirates, Qantas and Qatar Airways.
Virgin Atlantic chief customer and operating officer Corneel Koster said: ‘In parallel to the UK’s successful vaccination programme and accompanied by a risk-based, phased easing of restrictions, we can see a flightpath to soon allow the safe restart of international travel at scale, in time for summer.
‘When the skies reopen, rapid affordable testing combined with digital health integration will be vital to streamline and simplify the customer experience, make border health checks manageable and build consumer confidence.
‘Governments, industry and technology companies need to work together to lead the adoption of digital solutions with global common standards that are accepted at borders.’
