Vaccination against influenza and COVID-19

The risk of becoming seriously ill with influenza and COVID-19 increases with age. Therefore, everyone aged 65 and older are offered vaccination against both diseases from 1 October to 20 December.

The vast majority of people under the age of 65 are not at risk of serious illness. However, certain medical conditions increase the risk of developing serious illness from influenza and COVID-19, for example chronic heart or lung disease or a severely compromised immune system.

The Danish Health Authority therefore recommends that you also get vaccinated if you are under 65 and at increased risk of serious illness.

Influenza vaccination for children under 18 years of age with a chronic condition is offered following an individual medical assessment and consultation. For COVID-19 vaccination, the assessment is always carried out by a paediatrician. Only a small number of children need seasonal vaccination against COVID-19 and/or influenza.

The vaccination season begins on 1 October and ends on 20 December.

Seasonal vaccination against influenza and COVID-19 is offered at regional vaccination centres and by Danske Lægers Vaccinations Service from 1 October to 20 December.

If you are 65 years of age or older, you will receive an invitation from the Danish Health Authority and Statens Serum Institut via Digital Post during September 2026. You can then book an appointment at vacciner.dk.

You can access Digital Post through borger.dk, e-Boks.dk and mit.dk and via the Digital Post app. If you are exempt from Digital Post, you will receive an invitation letter by regular mail.

You will not receive an invitation via Digital Post if you are under 65 years of age.

From the end of September 2026, you can visit www.vacciner.dk to book an appointment if you have a disease or condition that makes you eligible for vaccination.

From the beginning of September, a research group will send letters to a large group of people inviting them to participate in the DAN-COMBO research trial. The trial is not part of the national vaccination programme.

If you choose to participate in the DAN-COMBO trial, you must follow the information and guidance you have received from the research group. Please note that you cannot also be vaccinated through the public vaccination programme if you participate in the research trial.

If you have questions about the trial or the invitation, please contact the research group behind DAN-COMBO. The research group’s contact details are provided in the invitation.

Yes, it is safe to be vaccinated against influenza and COVID-19 at the same time.

However, the vaccines must not be mixed in the same syringe, so you will need two separate injections.

All vaccines can cause side effects, including the influenza and COVID-19 vaccines. Some people may experience fever, headache or soreness at the injection site. These are common side effects that go away on their own.

Severe allergic reactions following vaccination are very rare. If you have previously had a severe allergic reaction after a vaccination or an injection with other medicine, you should talk to a doctor before getting vaccinated.

When the Danish Health Authority assesses whether a vaccine should be offered to a specific target group, both the vaccine’s effectiveness and its potential side effects are taken into account.

It is well known and expected that COVID-19 vaccines, like all other vaccines and medicines, can cause side effects. Based on the available evidence, the Danish Health Authority assesses that the benefits of the vaccines in preventing severe disease outweigh the risk of side effects.

Some people have reported experiencing a variety of symptoms and medical conditions following COVID-19 vaccination, either as newly developed symptoms or as a worsening of existing symptoms. If you suspect that you are experiencing long-term side effects after COVID-19 vaccination, it may be a good idea to discuss this with a doctor.

If you believe that you have suffered an injury as a result of vaccination, you may be eligible to apply for compensation from the Danish Patient Compensation (Patienterstatningen).

If you have a fever of 38 °C or higher or are suffering from an acute serious infection such as pneumonia, you should postpone vaccination until you have recovered.

You can still be vaccinated if you have a slight temperature or a common cold.

Older age is the most significant risk factor for severe influenza and COVID-19.

Therefore, as a general rule, we do not offer vaccination to people under the age of 65 unless they suffer from a specific chronic disease or have a condition that increases their risk of serious illness.

The Danish Health Authority no longer recommends vaccination against COVID-19 for healthy pregnant women. COVID-19 is now a much milder disease in younger, healthy people.

In recent years, we have seen very few pregnant women in Denmark being admitted to hospital due to COVID-19, and none have been so ill that they have required treatment in an intensive care unit.

The Danish Health Authority recommends that pregnant women, regardless of trimester, who have one of the conditions or diseases that puts them at increased risk of serious illness from COVID-19, be vaccinated in line with other people under the age of 65.

If you have a special health insurance card and belong to a group for whom vaccination is recommended, you may be eligble for vaccination in Denmark.

If you have MitID and are under 65 years of age, you can, if you are in the target group for vaccination, book an appointment for vaccination at vacciner.dk by completing a declaration confirming that you belong to a recommended target group.

If you do not have MitID or are 65 years of age or older, you can check whether any vaccination centres near you offer vaccination without an appointment (drop-in). When the vaccination programme begins, you can use the map on the front page of vacciner.dk to find your nearest vaccination centre and get an overview of vaccination locations across Denmark.

You can also contact your region’s hotline to find out about appointment options.

This year, an updated COVID-19 vaccine targeting the variants currently in circulation is being offered. The vaccine has been assessed and recommended by the European Medicines Agency (EMA).

Updating the vaccine to match the variants currently circulating is intended to provide the best possible protection against COVID-19.

People aged 69 or over are being offered an enhanced (adjuvanted) flu vaccine this year. The vaccine contains an adjuvant, which helps strengthen the immune response. It is therefore expected to provide slightly better protection against severe flu and hospitalisation in older people.

People aged 65 to 68, as well as other groups eligible for flu vaccination, are being offered a standard flu vaccine, as in the previous season.
