The FDA will add a new warning on the Johnson & Johnson Covid vaccines related to an autoimmune nerve disorder, according to the Washington Post.
According to WaPo, the Food and Drug Administration will say the J&J Covid jab has been linked to “serious but rare side effects called Guillain-Barré syndrome.”
Guillain-Barré is a disorder in which the immune system attacks the nerves.
The Food and Drug Administration is preparing to announce a new warning for the Johnson & Johnson coronavirus vaccine 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, according to four individuals familiar with the situation.
About 100 Preliminary reports of Guillain-Barré have been detected after the administration of 12.8 million doses of Johnson & Johnson vaccine in the United States, the Centers for Disease Control and Prevention said in a statement Monday. The cases have largely been reported about two weeks after vaccination and mostly in men, many aged 50 or older.
The Guillain-Barré cases are expected to be discussed as part of an upcoming meeting of the CDC’s Advisory Committee on Immunization Practices, the CDC said.
Guillain-Barré syndrome usually occurs at a rate of about 60 to 120 cases each week, according to CDC data. While the cause of the syndrome is not fully understood, it often follows infection with a virus, including influenza, or bacteria. Each year in the United States, an estimated 3,000 to 6,000 people develop the illness.
