Michael Kelly, 70, from Blaydon, Gateshead, who had his second jab almost seven months ago on April 23, said the booster rollout had been a “shambles”.
Mr Kelly, a retired taxi driver, has a chronic lung condition, making him clinically vulnerable. “It’s so frustrating, the amount of times I’ve had to phone 119,” he told The Telegraph.
Call handlers were unable to help Mr Kelly and told him to try his GP, who discovered his second jab had been recorded as taking place on June 18 – two months later than his actual vaccination.
Mr Kelly, who has spent weeks trying to book his booster, said he was concerned about his level of protection against Covid-19.
“There’s some people who are saying you’ve got very little protection [left after six months] and my GP is saying I should be alright, so then why are they telling me to get the booster if I’m going to be ‘alright’?” Mr Kelly said.
His case has been referred to a resolution team, but was told it could take “up to three weeks” before they contacted him, he claimed.
Healthwatch England, the patients’ watchdog, has also been notified by patients that errors on their vaccination records were blocking them from getting their booster.
One patient in Cheshire, who asked to remain anonymous, told the watchdog he was “struggling to book a booster dose online” and kept being rejected from the system.
Healthwatch England said: “It [the error] is preventing [them] from getting the booster vaccination as [they] believe the second vaccination has not been entered into the system correctly despite [them] having a card vaccination record that records both vaccinations.”
Charities have expressed concern that older patients are being prevented from getting their boosters at a time when their immunity is waning.
Caroline Abrahams, of Age UK said: “No older person should have to worry that they can’t get their booster because someone filled a form in wrongly or a data entry has gone astray.”
The Telegraph previously revealed there were 677,331 cases where NHS Covid vaccine records have had to be corrected.
The VDRS was launched to tackle the hundreds of thousands of errors found in people’s records.
An NHS spokesman said the service “supports people with missing or incorrect vaccination records” and anyone experiencing problems should contact 119.
