Denmark has put use of AstraZeneca's COVID-19 vaccine shots on hold for two weeks after reports of cases of blood clots forming, including one death, Danish authorities said on Thursday.
They did not say how many reports of blood clots there had been, but Austria has stopped using a batch of AstraZeneca shots while investigating a death from coagulation disorders and an illness from a pulmonary embolism.
"Both we and the Danish Medicines Agency have to respond to reports of possible serious side-effects, both from Denmark and other European countries," the director of the Danish Health Authority, Soren Brostrom, said in a statement.
