This past Monday the U.S. Food and Drug Administration added a new warning to the J&J COVID-19 vaccine fact sheet. This warning indicates an increased risk for an autoimmune disorder called Guillain-Barre syndrome. GBS causes a person’s immune system to attack its own peripheral nervous system.
The FDA suggests that J&J vaccine recipients should seek medical attention if they show symptoms such as weakness or tingling sensations in their legs or arms, have a hard time walking or hard time with facial expressions.
This warning is another setback for the J&J vaccine. It is also linked to a very rare but potentially life threatening blood clot condition. The CDC and FDA determined that the risk of blood clots was low and treatable.
