U.S. health officials say Johnson & Johnson’s COVID-19 vaccine may pose a “small possible risk” of a rare but potentially dangerous neurological reaction
WASHINGTON -- Johnson & Johnson’s COVID-19 vaccine may pose a “small possible risk” of a rare but potentially dangerous neurological reaction, U.S. health officials said Monday. The Centers for Disease Control and Prevention said in a statement it has received reports of 100 people who got the shot developing Guillain-Barré syndrome, an immune system disorder that can cause muscle weakness and occasionally paralysis. That number represents a tiny fraction of the nearly 13 million Americans who have received the one-dose vaccine. Most cases of the side effect were reported in men — many 50 years old and up — and usually about two weeks after vaccination. The CDC said it would ask its panel of outside vaccine experts to review the issue at an upcoming meeting. J&J didn’t immediately respond to a request for comment.More Related News
