Transport Secretary Grant Shapps has told the House of Commons that the government's Global Travel Taskforce will introduce a travel certification to allow people to travel abroad, APA reports citing BBC.
He says this could be done by using schemes like the International Air Transport Association's travel pass or the World Economic Forum's common pass.
He says he has been having conversations with his US counterparts and "many others around the world" in order to get "travel going again".
The transport secretary says the Global Travel Taskforce report will be made public on 12 April.
Shapps said on Wednesday that it was still too early to book a holiday.
Here is an explanation of how such certificates or vaccine passports could work.
