Danish health officials said they have temporarily halted the use of the Covid-19 vaccine made by AstraZeneca, as they and other European regulators investigate reports of severe blood clots in people who’ve received doses.
Denmark’s national health authority said it will pause use of the AstraZeneca vaccine, jointly developed with the University of Oxford, for at least two weeks. That includes a halt for people who have already had their first dose of the two-dose vaccine.
The U.K.'s medicines regulator urged people to continue receiving the AstraZeneca vaccine, calling the Danish decision to suspend use of the shot a "precautionary measure." The U.K. regulator said there was no confirmation of a link between blood clotting and the vaccine.
