AstraZeneca CEO says coronavirus vaccine trial participant had neurological symptoms

What's new: The participant was a woman from the United Kingdom who will likely be able to leave the hospital by Wednesday, Soriot reportedly told investors on a private conference call.

• He added that her condition is improving, though no diagnosis has yet been confirmed.
• He said that the board overseeing the clinical trial confirmed that the participant received a coronavirus vaccine and not a placebo.

Worth noting: Stat also reported that Soriot told investors the company's trial had briefly been halted in July after another patient experienced neurological symptoms, though that participant was later diagnosed with multiple sclerosis that was deemed unrelated to the trial.
