The number was confirmed in a Danish Medicines Agency statement on Thursday.

The agency stressed that it has not yet established a connection between the vaccine and blood clots.

“The Danish Medicines Agency is processing 10 reports filed in which blood clots or symptoms of blood clots occurring after vaccination are described in the reports,” the agency wrote in the statement.

“It cannot be concluded at the current time whether there may be a connection with the vaccine, because the cases have not been fully processed,” it added.

A total of 140,000 people in Denmark have received at least one dose of the AstraZeneca vaccine.

One person in Denmark, a 60-year-old woman has been reported to have died after receiving the vaccine. The woman was reported to have had an unusual medical history with a low number of platelets, blood clots in large and small blood vessels and bleedings.

It is not known whether her death is connected to the vaccine.

Other countries in Europe, including Denmark’s neighbour Norway, have also reported deaths in people who have recently received the AstraZeneca vaccine.

A group of medical experts at Oslo University Hospital said on Thursday that blood clots in three health workers who took the AstraZeneca vaccine were triggered by an immune system response.

The European Medicines Agency concluded on Thursday that the AstraZeneca vaccine was a “safe and effective” tool in the battle against Covid-19 but its investigation could not rule out whether the jab had caused rare cases of blood clotting.

New Covid-19 wave in Sweden ‘to peak at end of September’

Sweden's Public Health Agency has warned of a new autumn wave of Covid-19 which it expects to peak at the end of September.

New Covid-19 wave in Sweden 'to peak at end of September'

According to both of the two new scenarios published by the agency on Monday, infection rates are set to rise steadily over the next month, something the agency said was due to a falling immunity in the population and greater contact between people as they return to schools and workplaces after the summer. 

“It is difficult to say how high the peak will be, but it is unlikely that it will reach the same levels as in January and February,” the agency’s unit chief Sara Byfors said in a press release. “The most important thing is that people in risk groups and those who are 65 years old and above get vaccinated with a booster dose in the autumn to reduce the risk of serious illness and death.” 

Under Scenario 0, the amount of contact between people stays at current levels, leading to a peak in reported Covid-19 cases at around 5,000 a day. In Scenario 1, contact between people increases by about 10 percent from the middle of August, leading to a higher peak of about 7,000 reported cases a day. 

The agency said that employers should be prepared for many staff to be off sick simultaneously at points over the next month, but said in its release that it did not judge the situation to be sufficiently serious to require either it or the government to impose additional infection control measures. 

It was important, however, it said, that those managing health and elderly care continued to test those with symptoms and to track the chain of infections, that people go and get the booster doses when they are supposed to have under the vaccination programme, and that those who have symptoms of Covid-19 stay home.
