UK 'urgently reviewing' halted vaccine trial after volunteer falls ill
The U.K. Medicines and Healthcare products Regulatory Agency (MHRA) said it is "urgently reviewing all the information and actively engaging with the researchers to determine whether the trial should restart as quickly as possible," following news that AstraZeneca had paused its COVID-19 vaccine study being conducted with England's University of Oxford due to what the pharmaceutical company described as a "potentially unexplained illness in one of the trials."
The government body is responsible for deciding when the trial can resume.
"Participant safety in any clinical trial is our top priority," said Dr. Siu Ping Lam, the MHRA's director of licensing division, said in a statement Wednesday. "We are working with the Oxford Vaccine Centre following the temporary pause of their COVID-19 vaccine trial to allow for the review of safety data. This is in line with the authorized protocol for the trial."
The University of Oxford wouldn't give details on the participant's condition or whereabouts, citing patient confidentiality.
"Whilst it has been reported that one trial volunteer has become ill, this may be due to an issue related to the vaccine. It also may not," a university spokesperson told ABC News Wednesday morning.
During an interview with Sky News on Wednesday, British Secretary of State for Health and Social Care Matt Hancock revealed that it's not the first time the trial has been halted.
"It's not actually the first time it has happened to the Oxford vaccine and it's a standard process in clinical trials," Hancock said. "There was a pause earlier in the summer and that was resolved without a problem."
