Denmark has extended the suspension of COVID-19 vaccination with the AstraZeneca vaccine for another three weeks while it continues to assess the potential link between the vaccine and blood clots, AP reported.

Denmark's decision was based on the perceived side effects, Tanya Eriksen, a spokeswoman for the Danish Medicines Agency, told a press conference.

Denmark suspended the use of the AstraZeneca vaccine as a precaution on March 11 after reports that a 60-year-old woman died of blood clots a week after vaccination.

Another reported death in Denmark, who died after being vaccinated with AstraZeneca. Danish health authorities said they had no proof that the vaccine was the cause of death.

Several European countries that have suspended use of the vaccine have resumed use after the European Medicines Agency said it was safe.

Over 1 million doses of various vaccines have been administered in Denmark, with a population of almost 6 million, according to the European Center for Disease Prevention and Control. About 150,000 people in Denmark have been vaccinated with AstraZeneca.

The European Medicines Agency said the benefits of the vaccine still outweigh the risks, and the vaccine can continue to be administered while more careful evaluation of blood clots continues.
