UK (Reuters) – Europe’s medicines regulator has added an extremely rare nerve-damaging disorder, Guillain-Barré syndrome, as a possible side-effect of AstraZeneca’s (AZN.L) COVID-19 vaccine, regular safety updates from the watchdog showed last week. The European Medicines Agency said a causal relationship between GBS and the AstraZeneca shot, known as Vaxzevria, was a “at least a reasonable possibility” after 833 cases of GBS were reported out of 592 million doses of the vaccine given worldwide by July 31. The EMA categorised the side-effect as “very rare”, the lowest frequency of side-effect category it has, and has emphasised that the benefits of the shot outweigh the risks. The US Food and Drug Administration has added a warning over Guillain-Barré syndrome as a possible side-effect of Johnson & Johnson’s (JNJ.N) shot. Both vaccines use viral vector technology, and have also been associated with rare blood clots.
