AN investigation into a blunder at a Tyne Valley medical practice has been completed.

The investigation was launched by Northumbria Primary Care after hundreds of patients at Haydon Bridge and Allendale Medical Practice were told vaccinations they received at the practice may not have been effective due to a refrigeration error.

The findings are now being reviewed by several bodies to ensure that the situation does not occur again.

The practice came under fire after the issue was not picked up between November 2017 and September 2018, with 333 people affected as a result.

Vaccines affected included childhood immunisations, shingles and pneumonia for the elderly, as well as travel-related jabs, and some people may need to be re-vaccinated as a result of the error.

The management at the practice, which has surgeries in both villages, stated that the risk of harm to patients had been minimal, and that there had been a full investigation carried out into the issue.

A spokeswoman for Northumbria Primary Care, which manages Haydon Bridge and Allendale Medical Practice, said: “We have carried out a thorough investigation into this issue and are working with NHS England, NHS Northumberland Clinical Commissioning Group and Public Health England to review our findings and ensure any wider lessons are shared.”
