The Food and Drug Administration (FDA) is reportedly set to announce a warning for the Johnson & Johnson coronavirus vaccine saying it has been linked to a serious, although rare, side effect.
The side effect is known as Guillain-Barré syndrome (GBS), the Washington Post reportedMonday:
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 and older.
Available data do not show a pattern suggesting a similar increased risk with the Pfizer-BioNTech and Moderna vaccines, after more than 321 million doses of those vaccines have been administered in the United States.
According to the Centers for Disease Control and Prevention (CDC) website, GBS is a rare disorder whereby a person’s immune system damages nerves which causes muscle weakness and sometimes paralysis.
“While its cause is not fully understood, the syndrome often follows infection with a virus or bacteria. Each year in the United States, an estimated 3,000 to 6,000 people develop GBS. Most people fully recover from GBS, but some have permanent nerve damage,” the agency noted.
