The European Union’s drug regulator has started a review to assess blood clots in people who received Johnson & Johnson’s Covid-19 vaccine.

Four serious cases of unusual clots accompanied by low blood platelets, one of which was fatal, have emerged after immunization with the J&J shot, the European Medicines Agency said Friday. The regulator is now scrutinizing potential safety issues for two Covid vaccines, after AstraZeneca Plc’s shot was possibly linked to a rare blood-clotting disorder.
