Scientists relieved as coronavirus vaccine trial restarts — but question lack of transparency

Oxford–AstraZeneca vaccine trial restarts

The trial of a leading vaccine candidate from the University of Oxford and pharmaceutical company AstraZeneca restarted in the United Kingdom on Saturday. Enrolment in global trials was paused on 6 September, after a person participating in the UK trial experienced an adverse reaction. Such pauses are not uncommon in large trials — this was the second time that this trial had been put on hold. But some scientists have criticised the trial sponsors for not being more transparent. The University of Oxford and AstraZeneca have not yet released details of the adverse reaction that led to the trial pause and how the decision to resume the UK study was made. It is also not known whether trials of the vaccine in South Africa, Brazil and the United States will resume.
