Up to 700,000 vaccine passports have been affected by NHS blunders, locking many people out of foreign travel, after the wrong data was recorded by health officials, the Telegraph can reveal.
Ministers have said Covid passes – already used for travel to dozens of countries – will become compulsory for entry to nightclubs and large venues by the end of next month.
But hundreds of thousands of vaccine records have now been found to contain errors, including those which have left double-jabbed people without the proof they need.
The blunders have left families unable to go on holiday, or visit loved ones abroad, with some even resorting to having a third jab after desperate calls failed to resolve the matter.
Freedom of Information disclosures revealed 677,331 cases in which NHS Covid vaccine records have had to be corrected. In addition, health officials admitted to 112,939 cases in which records had to be deleted because of corrections or where duplicate entries had been found.
Experts said the figures from NHS Digital were likely to be the tip of the iceberg, with many errors only coming to light when holidaymakers checked the NHS app and found their pass was missing.
The NHS is set to launch a Vaccination Data Resolution Service in order to deal with the growing crisis.
A job advertisement for call agents says the seven-day service will “support citizens resolving problems they encounter with their Covid-19 vaccination records” and be essential “in enabling citizens to to prove their Covid-19 vaccination status in line with UK Government guidance”.
