The boss of the world's busiest airport for international passengers has said Covid passports are the only way to restart mass foreign travel.
Dubai Airports chief executive Paul Griffiths told the BBC: "I don't think there is an alternative."
Critics of the digital systems argue they discriminate against those who cannot get vaccinated.
But Mr Griffiths says he is a complete supporter of the documents, which he says are "inevitable".
"I think the problem is not the vaccine passport and its discrimination. It's the need to roll things out and have a proper globally equitable vaccine programme," he said.
