British clinical trials for the AstraZeneca and Oxford University coronavirus vaccine have resumed following confirmation by the Medicines Health Regulatory Authority (MHRA) that it was safe to do so, the company said.

The late-stage trials of the experimental vaccine, one of the most advanced in development, were suspended this week after an illness in a study subject in Britain.

“The standard review process triggered a voluntary pause to vaccination across all global trials to allow review of safety data by independent committees, and international regulators,” AstraZeneca said.

“The UK committee has concluded its investigations and recommended to the MHRA that trials in the UK are safe to resume.”
