Denmark has temporarily suspended the use of AstraZeneca’s Covid-19 vaccine as a precaution after some patients developed blood clots after receiving the jab.
It comes after five countries halted use of one batch of the AstraZeneca jab after concerns over fatal blood clots.
In a tweet, Denmark’s Minister for Health Magnus Heunicke said the measure was a precaution and it was not possible to say whether there was definitely a connection between the vaccine and fatal blood clots.
“The health authorities have, due to precautionary measures, suspended vaccination with AstraZeneca following a signal of a possible serious side effect in the form of fatal blood clots.
“It is currently not possible to conclude whether there is a connection. We act early, it needs to be thoroughly investigated,” he wrote.
On Thursday Austria national medicines regulator suspended use of a batch of the AstraZeneca vaccine after four patients were diagnosed with dangerous blood clotting conditions after receiving their jab.
According to the European Medicines Agency (EMA), one person died of multiple thrombosis – formation of blood clots within blood vessels – 10 days after their vaccine.
The EMA said there is currently no evidence that the vaccine caused the conditions, and that thrombosis is not listed as a potential side effect of the vaccine.
