Danish health authorities said Thursday they were temporarily suspending the use of AstraZeneca's Covid-19 vaccine as a precaution after some patients developed blood clots since receiving the jab. The move comes "following reports of serious cases of blood clots among people vaccinated with AstraZeneca's Covid-19 vaccine", the Danish Health Authority said in a statement. But it cautiously added that "it has not been determined, at the time being, that there is a link between the vaccine and the blood clots". cbw/po/jv
