Oxford vaccine trial on hold because of safety issue

“Our standard review process was triggered and we voluntarily paused vaccination to allow review of safety data by an independent committee,” the company said in a statement. “This is a routine action which has to happen whenever there is a potentially unexplained illness in one of the trials, while it is investigated, ensuring we maintain the integrity of the trials.”

The statement continued: “In large trials illnesses will happen by chance but must be independently reviewed to check this carefully. We are working to expedite the review of the single event to minimize any potential impact on the trial timeline. We are committed to the safety of our participants and the highest standards of conduct in our trials.”
