Europe’s drug regulator on Thursday confirmed it is investigating reports of a blood condition in recipients of Moderna’s mRNA COVID-19 vaccine.

According to a bulletin posted by the European Medicines Agency (EMA), it is reviewing six cases of capillary leak syndrome, considered a “very rare disorder,” after they were reported in the EMA’s EudraVigilance database.
