Immunity certificates to last for six months and appear as a green badge on the NHS app under new trial

The Government has announced that up to 20 events will be part of the trial scheme, which will see Wembley filled to half capacity for the final four games of Euro 2020, while Wimbledon’s Centre Court will be filled to capacity for the men’s and women’s singles finals.
Silverstone will host larger crowds than allowed under the national regulations for the British GP on July 18, while Andrew Lloyd Webber’s new production, Cinderella, has been mooted by Boris Johnson as a possible theatre test for Covid passports.
Officials are using the trials to assess how to reopen events safely by measuring the impact of attendees being indoors or outdoors and seated or standing.
Although ministers have signed off the use of vaccine passports for international travel, their domestic use is controversial. Boris Johnson has ordered a review into the scheme, chaired by Michael Gove, which will report before the last stage of easing of lockdown, now due to take place on July 19.
It is understood any eventual passport is likely to function through the NHS app and could include information about a user’s vaccines and test status, although it could also include natural immunity for six months if the new trials are successful.
Private businesses are free to ask their customers to prove vaccine status, but any attempt to mandate vaccine passports in law is likely to meet opposition from MPs on both sides of the House of Commons.
On Tuesday, Mr Gove said that while the delay to stage four of the roadmap from June 21 to July 19 was “regrettable”, it did allow officials more time to test vaccine passports before their possible rollout.
“Ultimately, we want to be in a position where people can use the app for international travel and where domestically we can open up completely,” he said. “But these trials […] will help us understand what the risks and benefits are.”
