Guillain-Barre syndrome: FDA flags ‘small’ risk with J&J jab

US health officials issue new warning over rare neurological reaction for people getting the one-shot Johnson & Johnson vaccine.

United States regulators have added a new warning to Johnson & Johnson’s COVID-19 vaccine about links to a rare and potentially dangerous neurological reaction. The Food and Drug Administration (FDA) announced the new warning on Monday, flagging reports of Guillain-Barre syndrome, an immune system disorder that can cause muscle weakness and occasionally paralysis. Health officials described the side effect as a “small possible risk” for those getting the shot. The new warning will be included in pamphlets given to people getting the Johnson & Johnson shot. They should seek medical attention if they experience any symptoms, which include tingling sensations, trouble walking and double vision, the regulators said.
