People who receive the Johnson & Johnson COVID-19 vaccine are at elevated risk of getting a severe autoimmune disorder that can cause paralysis, according to a new study.
Researchers used data from the Vaccine Safety Datalink, which is run by the Centers for Disease Control and Prevention (CDC). They found (pdf) 21 potential cases, 11 of which were confirmed, of Guillain-Barré syndrome (GBS) in people who got the shot. Most happened with 13 days of vaccination.
