Drugmaker AstraZeneca will resume the trial of its experimental coronavirus vaccine in the United States, which has been on hold since September.
The company said the US Food and Drug Administration authorized the restart Thursday after reviewing all of the global safety data and concluding it was safe to resume. The trial had already resumed in other countries.
The trial was paused after a volunteer in Britain developed a neurological condition suffered by one of the participants in its coronavirus vaccine clinical trials around the world.
