The Food and Drug Administration announced a new warning for the Johnson & Johnson coronavirus vaccine on Monday, saying the shot has been linked to a serious but rare side effect called Guillain-Barré syndrome, in which the immune system attacks the nerves.
About 100 preliminary reports of Guillain-Barré have been detected in vaccine recipients of the Johnson & Johnson vaccine in the United States, according to a companion statement from the Centers for Disease Control and Prevention, which monitors vaccine safety systems with the FDA. Of these reports, 95 were serious and required hospitalization, the FDA statement said. There was one death.
The cases have largely been reported about two weeks after vaccination and mostly in men, many aged 50 and older, according to the CDC.
Earlier, a pause was recommended after reports of cases of a rare and severe type of blood clot in individuals following administration of COVID-19 Vaccine. During the pause, medical and scientific teams examined available data to assess the risk of thrombosis involving the cerebral venous sinuses, or CVST (large blood vessels in the brain), and other sites in the body (including but not limited to the large blood vessels of the abdomen and the veins of the legs) along with thrombocytopenia, or low blood platelet counts.
