The Oxford-AstraZeneca vaccine has been claimed to be “defective” according to a landmark legal case.

The Covid jab which was given to thousands in the UK is facing claims that its efficacy was “vastly overstated”.

The test case has been brought forward by Jamie Scott who was left with a permanent brain injury as a result of a blood clot after he received the jab in April 2021.

A second claim is being brought forward by the widower of Alpa Tailor, who died after receiving the vaccine.

AstraZeneca told the Telegraph that patient safety was its “highest priority”.

It added that its vaccine had “continuously been shown to have an acceptable safety profile” and that regulators around the world “consistently state that the benefits of vaccination outweigh the risks of extremely rare potential side effects”.
