The European Medicines Agency (EMA) said on Friday it has started a review to assess blood clots in people who received Johnson & Johnson’s (J&J) Covid-19 vaccine.

The EU medicine’s regulator said its safety committee "has started a review of a safety signal to assess reports of thromboembolic events" after reports of four cases, one of them fatal.
