The reduction in supply will be spread across deliveries until the end of June, Danish infectious disease agency State Serum Institute (SSI) confirmed in a statement.
Denmark will receive fewer doses because AstraZeneca has halved the number of vaccines it expects to supply to the EU over the coming months.
“That AstraZeneca is yet again reducing the number of doses that will be delivered to the EU and thereby Denmark is naturally both dissatisfying and seriously challenging,” SSI deputy director Ole Jensen said in the statement.
Another supplier, Moderna, will also deliver fewer doses to Denmark in April, May and June than expected, according to the most recently-updated Danish Health Authority vaccination calendar. The exact reduction is not stated.
Denmark will now receive 2.2 million fewer vaccine doses in the second quarter of 2021 than was originally planned for according to newspaper Ekstra Bladet, which compared the new vaccine calendar with the previous one. The country is currently set to receive 5.5 million doses in the second quarter of 2021.
On Thursday, Danish health authorities said 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, one of whom died.
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”.
