The Food and Drug Administration is warning about a possible link between Johnson and Johnson's COVID-19 vaccine and an increased risk of a rare and potentially dangerous neurological reaction.

U.S. health officials say 100 people who got the shot developed an immune system disorder called Guillain Barré syndrome.

Most people make a full recovery.

It causes occasional paralysis and muscle weakness.

There are no reports that anyone who got the Pfizer or Moderna shot have developed Guillain Barré syndrome.

Johnson and Johson released a statement on their website saying in part, "The safety and well-being of the people who use our products is our number one priority. Rare cases of the neurological disorder, Guillain-Barré syndrome have been reported following vaccination with the Janssen COVID-19 vaccine. Most occurred within 42 days after vaccination."

Johnson & Johnson adding the chance of having this is occur is very low.
