Covid-19 vaccine.Four serious cases of unusual clots accompanied by low blood platelets, one of which was fatal, have emerged after vaccination with the J&J shot, the European Medicines Agency said Friday.
One happened during a clinical trial -- at the time, J&J said it had found no evidence the vaccine was at fault -- and three others occurred in the U.S., where the shot is being widely used.Though J&J’s shot is approved in the EU, its rollout in the bloc isn’t expected to start until later this month.
Still, the EU is relying on the one-shot vaccine to boost its immunization drive amid restrictions in some countries on use of the AstraZeneca Plc shot.
