Johnson & Johnson's COVID-19 Vaccine Is Linked To A Rare Neurological Disorder

Last week, European regulators recommended a similar warning for AstraZeneca's COVID-19 vaccine, which is based on a similar technology as Johnson & Johnson's one-dose shot.

The warning is another setback for the J&J vaccine, which was supposed to be an important tool for vaccinating in hard-to-reach areas and among those hesitant to be vaccinated because it requires only one shot and has less stringent storage requirements than the Pfizer or Moderna vaccines.
