Two people have fallen ill during the trials of AstraZeneca’s coronavirus vaccine in the UK, the company’s internal papers revealed, and a source said they had both suffered from the same serious neurological disorder.
The company published details of the trials on Saturday, after facing criticism over the lack of transparency surrounding the testing of the much-anticipated vaccine against the virus, which has so far infected more than 30.8 million people and caused over 958,000 fatalities worldwide.
The first participant of the British trials – which are being conducted in conjunction with Oxford University – fell ill after receiving one dose of the experimental vaccine in July.
The female volunteer was later diagnosed with transverse myelitis, a rare inflammatory disease that affects the spinal cord, causing weakness, sensory alterations, and autonomic nervous-system dysfunction. The company’s spokeswoman later told the media the volunteer had undiagnosed multiple sclerosis, and the trials resumed.
