scientists could look at samples from other vaccinated patients to see whether any of the antibodies they generated in response to the coronavirus also attack brain or spinal cord tissue. The NIH has yet to get tissue or blood samples from the British patient, and its investigation is “in the planning stages,” Nath said. The last thing you want to do is hurt healthy people.” “So many factors go into these decisions,” Nath said. “We would like to see how we can help, but the lack of information makes it difficult to do so.”Īny decision about whether to continue the trial is complex because it’s difficult to assess the cause of a rare injury that occurs during a vaccine trial - and because scientists and authorities have to weigh the risk of uncommon side effects against a vaccine that might curb the pandemic.ĪstraZeneca's Oxford vaccine trial to resume, the university says Britain’s regulatory body, the Medicines and Healthcare Products Regulatory Agency, reviewed the case and has allowed the trial to resume in the United Kingdom.ĪstraZeneca “need to be more forthcoming with a potential complication of a vaccine which will eventually be given to millions of people,” said Nath. ![]() Transverse myelitis produces a set of symptoms involving inflammation along the spinal cord that can cause pain, muscle weakness and paralysis. AstraZeneca, which is running the global trial of the vaccine it produced with Oxford University, said the trial volunteer recovered from a severe inflammation of the spinal cord and is no longer hospitalized.ĪstraZeneca has not confirmed that the patient was afflicted with transverse myelitis, but Nath and another neurologist said they understood this to be the case. ![]() Here's why a vaccine will not stop the Covid-19 pandemic right awayĪ great deal of uncertainty remains about what happened to the unnamed patient, to the frustration of those avidly following the progress of vaccine testing. A man receives an injection as UCLA and AstraZeneca begin phase three trials in a potential COVID-19 vaccine.
