How many double-vaccinated people in Denmark have been infected with Covid-19?

Denmark’s national infectious disease agency State Serum Institute (SSI) says that Covid-19 vaccines used by the country give good protection against the virus, but the impact of the Delta variant is yet to become apparent.

A total of 1,233 fully vaccinated people in Denmark have subsequently tested positive for the coronavirus, according to the agency.

The 1,233 infections occurred amongst 1.6 million people who completed vaccination between December 27th, 2020 and June 30th, 2021. That corresponds to an infection rate of 0.08 percent for fully vaccinated persons.

Those numbers indicate good protection against the virus is provided by the vaccines, according to SSI’s professor and head of department Troels Lillebæk, who provided comment to broadcaster DR.

“This is a very small number and it shows how effective the vaccines are,” Lillebæk said.

Fully vaccinated people are also more likely to experience more mild illness with the virus should they become infected, the senior SSI official said.

“Typically, if you are fully vaccinated, you will have a mild illness and rarely be admitted to hospital. The people we are seeing at hospitals now are the ones who are unvaccinated or those who have just received one dose,” Lillebæk told DR.

University of Copenhagen vaccine researcher Camilla Foged said the numbers were “very good” and added that it should be expected that a number of vaccinated people may still catch the virus.

Foged urged vaccinated people to remain cautious give full protection from vaccines is gained around two weeks after the second dose is given.

“My message to young people is that they should take care until they are fully vaccinated. You are not very well protected by a single dose, so you can still get Covid (after receiving the first dose),” she told DR.

The figures released by SSI cover the period up to the end of June. As such, the effect of the Delta variant on infections is not yet apparent, Lillebæk noted.

Vaccine effectiveness is “reduced a little” against the Delta variant, Foged said, meaning that more double-vaccinated people are likely to be infected with the variant.

After accounting for under one percent of new cases at the beginning of June, Delta recently took over as the country’s dominant variant of Covid-19 and now makes up almost 80 percent of new cases.

IN NUMBERS: Has the Omicron Covid-19 wave peaked in Denmark?

The number of new Covid-19 infections fell on Saturday for the second day in a row, following a three-day plateau at the start of last week. Has the omicron wave peaked?

How many cases, hospitalisations and deaths are there in Denmark? 

Denmark registered 12,588 new cases in the 24 hours leading up to 2pm on Saturday, down from the 18,261 registered on in the day leading up to Friday at 2pm, which was itself a decline from the record 28,283 cases recorded on Wednesday. 

The cases were identified by a total of 174,517 PCR tests, bringing the positive percentage to 7.21 percent, down from the sky high rates of close to 12 percent seen in the first few days of January. 

The number of cases over the past seven days is lower than the week before in almost every municipality in Denmark, with only Vallensbæk, Aarhus, Holseterbro, Skanderborg, Hjørring, Vordingborg,  Ringkøbing, Kolding, Assens, Horsens, Thisted, and Langeland reporting rises. 

Hospitalisations have also started to fall, with some 730 patients being treated for Covid-10 on Saturday, down from 755 on Friday. On Tuesday, 794 were being treated for Covid-19 in Danish hospitals, the highest number since the peak of the 2020-21 winter wave.

The only marker which has not yet started to fall is the number of deaths, which tends to trail infections and hospitalisations. 

In the 24 hours leading up to 2pm on Saturday, Denmark registered 28 deaths with Covid-19, the highest daily number recorded since 20 January 2021, when 29 people died with Covid-19 (although Denmark’s deadliest day was the 19 January 2021, when 39 people died). 

How does Denmark compare to other countries in Europe? 

Over the last seven days, Denmark has had the highest Covid-19 case rate of any country in Europe bar Ireland. The number of new infections in the country has climbed steadily since the start of December, apart from a brief fall over Christmas. 

So does this mean the omicron wave has peaked? 

Maybe, although experts are not sure. 

“Of course, you can hope for that, but I’m not sure that is the case,” said Christian Wejse, head of the Department for Infectious Diseases at Aarhus University Hospital. “I think it is too early to conclude that the epidemic has peaked.”

He said that patients with the Omicron variant were being discharged more rapidly on average than had been the case with those who had the more dangerous Delta variant. 

“Many admissions are relatively short-lived, thankfully. This is because many do not become that il, and are largely hospitalized because they are suffering with something else. And if they are stable and do not need oxygen, then they are quickly discharged again.” 

Denmark’s Prime Minister Mette Frederiksen said during a visit to an event held by the Social Liberal party that the latest numbers made her even more optimistic about the coming month. 

“We have lower infection numbers and the number of hospitalisations is also plateauing,” she said. “I think we’re going to get through this winter pretty well, even if it will be a difficult time for a lot of people, and we are beginning to see the spring ahead of us, so I’m actually very optimistic.” 

She said that she had been encouraged by the fact that Omicron was a “visibly less dangerous variant if it is not allowed to explode.”
