Denmark  reported on Saturday two cases of hospital staff with blood clots and cerebral haemorrhage after receiving the AstraZeneca coronavirus vaccine.

The Capital Region of Denmark, the authority that runs public hospitals in Copenhagen, noted that one of the hospital staff had died and both had received the AstraZeneca vaccine less than 14 days before getting ill.

The Danish medicines agency confirmed having received two ‘serious reports’, without elaborating.

There were no details of when the hospital staff got ill.

This week, some countries including France and Germany reversed their decision to temporarily pause use of the AstraZeneca vaccine after reports of cases of rare brain blood clots sent scientists and cabinets scrambling to determine any link.

Denmark, which put use of the vaccine on hold on March 11, has not yet resumed its use.

On Thursday, the European Union’s drug watchdog said it is still convinced the benefits of the AstraZeneca vaccine outweigh the risks following an investigation into reports of blood clots that prompted more than a dozen nations to halt its use.

Emer Cooke, European Medicines Agency (EMA) director, said on Thursday the watchdog could not definitively rule out a link between blood clot incidents and the vaccine in its investigation into 30 cases of a rare blood clotting condition.

However, she added that the “clear” conclusion of the review was that the benefits in protecting people from the risk of death or hospitalization outweighs the potential risks. The issue deserves further analysis, the EMA said.

AstraZeneca, which developed the shot with Oxford University, has said a review covering more than 17 million people who had received its doses in Britain and the EU had found no evidence of an increased risk of blood clots.
