The Danish Health Authority on Thursday halted the use of the AstraZeneca coronavirus vaccine for 14 days. It follows reports of “serious cases of blood clots among vaccinated people,” a statement read. However, the authority stopped short of saying there was a direct link between the vaccine and the blood clots, “at the time being.” “It is currently not possible to conclude whether there is a link. We are acting early, it needs to be thoroughly investigated,” Danish Health Minister Magnus Heunicke said on Twitter. Shortly after the announcement, Iceland and Norway both halted the rollout of the vaccine.
