The NHS App was today updated with 'domestic' and 'travel' options for Britons who have had both doses of the Covid-19 jab, who can also now add their vaccine certificate to their Apple Wallet. Developers also made a change so that people who received the Novavax jab as part of a formally-approved vaccine trial can now obtain the so-called 'NHS Covid Pass'. And those opening up the Covid section of the app can now go through to the 'get your NHS Covid Pass' – which presents two options of 'domestic' or 'travel'. Responding to news of the app's update, the Liberal Democrats argued that the Government had 'introduced Covid ID Cards by stealth onto the nation's phones'. It comes after the Government proposed making vaccine passports mandatory in nightclubs from September - and this could extend to students going to university. If it is at least 14 days since you have received a second jab, the 'domestic' section of the app will display your name, date of birth and a QR code confirming your jabs. The 'travel' section contains the same information along with nine extra details for each dose - including the date of vaccination, product, manufacturer, vaccine, bath number, disease, country of vaccination, issuer and the administrating centre.

The Lib Dems today called for a recall of Parliament over the updated app, with the party's home affairs spokesman Alistair Carmichael saying: 'The government has just committed to vaccine passports by stealth. 'This deceitful move is deeply shameful. We now have a new ID card snuck onto our phones without even as much as a whisper from the government. 'Just this morning, Ministers on TV and radio were flapping about when asked simple questions how this would actually work. Now it is on all our phones.' He added that getting to the vaccine passport means having to 'type and click through a bunch of options', adding: 'Just think of the faff getting into hospitality businesses, who don't want it and can't afford to pay staff to police it. The 'travel' section contains the same information as 'domestic' along with nine extra details for each dose - including the date of vaccination, product, manufacturer, vaccine, bath number, disease, country of vaccination, issuer and the administrating centre This is what appears in the Apple Wallet section of your phone once you've added the pass 'The Conservatives are no strangers to a U-turn. They should have no problem with doing the right thing and scrapping vaccine passports for good. 'At least when Tony Blair tried to introduce ID cards he put a bill to Parliament, this lot won't even open up Parliament to debate it. They must recall Parliament now if they are serious about this.' The NHS Covid Pass is available to adults over two weeks after having both jabs, or after having a negative PCR or rapid lateral flow test within 48 hours. The Pass can also provide proof of natural immunity from a positive PCR test up to 180 days from the date of the positive test after self-isolating. The text about the latest update on the Gov.uk website today said: 'Updated to reflect that proof of natural immunity shown by a positive PCR test can be used to demonstrate Covid-19 status when travelling abroad.' It added: 'The NHS Covid Pass can be stored in the AppleWallet when using an iPhone or iPad; and those who received the Novavax vaccine as part of a formally approved vaccine trial, can now obtain the NHS Covid Pass.' Boris Johnson suggested yesterday that vaccine passports could be needed across a range of mass events, as the prospect of their widescale use moved closer. The Prime Minister said that getting a jab would 'help, not hinder' when people were travelling abroad or attending large gatherings in future. The Government announced last week that proof of double vaccination will be a 'condition of entry' to clubs and other busy venues from September. But yesterday Mr Johnson appeared to give a clear hint at the future direction of policy, suggesting the documents could also be needed for a range of events. Mr Johnson has also confirmed that self-isolation rules are 'nailed on' to end on August 16 for the double jabbed, bringing hope of an end to the 'pingdemic' chaos. From this date, the fully vaccinated will not have to stay indoors even if someone in their household gets the virus. They will also not have to take a test. The Prime Minister said the jab rollout should allow for a 'very, very strong' economic recovery in the second half of this year. The developments came a day after a senior minister said the vaccine success story meant Covid's grip on the UK was 'all over bar the shouting'.
