The U.S. Food and Drug Administration is expected to announce a new warning on Johnson & Johnson's coronavirus vaccine related to a rare autoimmune disorder, the Washington Post reported on Monday, citing four people familiar with the matter.

According to the Post, about 100 preliminary reports of Guillain-Barré syndrome (GBS) have been detected in the United States after vaccination with J&J shot, mostly in men, many of whom were 50 or older. Around 12.8 million people have received the one-dose vaccine in the United States. J&J and the FDA were not immediately available for comment.

GBS is a rare neurological condition in which the body's immune system attacks the protective coating on nerve fibers. Most cases follow a bacterial or viral infection. The condition has been linked in the past to vaccinations - most notably to a vaccination campaign during a swine flu outbreak in the United States in 1976, and decades later to the vaccine used during the 2009 H1N1 flu pandemic.
