The European Medicines Agency (EMA) is to review the link between reports of blood clotting and the Johnson & Johnson Covid-19 vaccination.
The review follows four reports of blood clotting post-vaccination with one being fatal. Three of the cases occurred during a vaccine rollout while one case occurred during a clinical trial in the USA.
Although the Johnson & Johnson vaccine has been approved for use, the EU rollout will not commence until later this month. In addition to this, the EMA is currently reviewing the AstraZeneca vaccine due to reports of a rare blood vessel disorder.
The EMA has stated that a decision will be made on whether regulatory action will be taken after both vaccinations are investigated.
