The BioNTech/Pfizer and Oxford/AstraZeneca coronavirus vaccines are associated with seven rare neurological complications, according to the most comprehensive study of the side effects from the two jabs.
Using data from 32m vaccinated adults in England, researchers estimated that an extra 38 people per 10m who received their first Oxford/AstraZeneca shot suffered from Guillain-Barré syndrome, which causes pain and weakness in the limbs and is usually temporary, than would do in the general population.
They found an increased risk of haemorrhagic stroke, a brain bleed, in the 28 days after vaccination with the BioNTech/Pfizer shot, at an estimated 60 extra cases per 10m people. The increased risk was significantly higher in female patients.
