To review, AstraZeneca yesterday suspended its Phase 3 trial of Covid-19 vaccine candidate AZD1222 after one U.K. participant suffered a serious adverse reaction.
It was reported today that the reaction was a rare inflammatory condition affecting the spinal cord called transverse myelitis, that is caused by infections or immune system disorders.
The company a short time ago said those reports are incorrect, and that there’s been no final diagnosis of yet. The company also confirms that there was a short pause in the trial in July after one volunteer was confirmed to have an undiagnosed case of multiple sclerosis, unrelated to the vaccine.
