The European Union’s medicines regulator said on Tuesday that there is a “possible link” between Johnson & Johnson’s COVID-19 vaccine and blood clots, but said its “overall benefit-risk remains positive.”

At a meeting on Tuesday, the safety committee of the European Medicines Agency (EMA) concluded that a warning about unusual blood clots should be added to the product information for COVID-19 Vaccine Janssen, which was developed by Janssen, a subsidiary of Johnson & Johnson.
