People with chronic disease are offered vaccination against influenza and COVID-19

If you have a chronic illness or a specific medical condition that increases your risk of severe illness from influenza or COVID-19, the Danish Health Authority recommends that you get vaccinated, regardless of your age. Vaccination is offered free of charge from 1 October to 20 December.

Advanced age is the most significant risk factor for severe influenza and COVID-19. However, some people under the age of 65 have diseases or conditions that increase their risk of becoming seriously ill from these infections.

Certain chronic diseases and conditions can weaken the immune system and the body's ability to fight infections. This may make it easier to develop severe illness and increase the risk of complications such as pneumonia. Many people living with a medical condition are aware that they are at increased risk of a severe course of influenza or COVID-19 and are therefore recommended vaccination. If you are unsure whether this applies to you, the list below may help.

The Danish Health Authority recommends that the following people under the age of 65 be offered vaccination against influenza and COVID-19:

People with chronic disease, including:
- People with chronic lung diseases.
- People with cardiovascular diseases (except isolated, well-controlled high blood pressure).
- People with type 1 or 2 diabetes.
- People with congenital or acquired immunodeficiency, for example people with immunoglobulin defects, organ or stem cell transplants, people with cancer undergoing chemotherapy or people undergoing other immunosuppressive treatment.
- People with respiratory impairment due to muscle weakness.
- People with chronic liver or kidney disease.
- People with other chronic diseases where the condition means that influenza or COVID-19 poses a serious health risk, for example people with severe rheumatological disease, severe neurological disease or short bowel syndrome.
People who are severely overweight (BMI>35).
People with other serious diseases or conditions that mean that influenza or COVID-19 poses a serious health risk, for example people with severe mental illness, Down’s syndrome or severe substance abuse disorder.
Pregnant women in their second or third trimester are offered vaccination against influenza.
People in the same household as people with congenital or acquired immunodeficiency or people in the same household as children at increased risk of severe influenza or COVID-19.

People receiving a disability pension are also offered free vaccination against influenza.

Vaccination of children under 18 years of age with chronic disease is done after medical assessment and advice. For COVID-19, 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 Danish Health Authority recommends COVID-19 vaccination for pregnant women, regardless of trimester, if they have one of the above-mentioned conditions or diseases. COVID-19 vaccination is not offered to healthy pregnant women.

Even if you have previously been vaccinated, it is important that you get vaccinated again. Protection from vaccination decreases over time and influenza viruses and coronavirus continue to evolve. When you get vaccinated again, you will be better protected against these diseases during the winter season.

Vaccination is free of charge and voluntary.

Questions and answers

1. How do I book an appointment for vaccination against influenza and COVID-19?

If you are aged 18-64 and are recommended vaccination due to an increased risk of serious illness, for example due to a chronic disease or condition that increases the risk of serious illness, you will not receive an invitation. You must book an appointment yourself.

From 29 September 2025, you can go directly to vacciner.dk, where you can book an appointment after completing a solemn declaration.

2. When can I get vaccinated against influenza and COVID-19?

You can be vaccinated against influenza and COVID-19 from 1 October 2025 to 20 December 2025.

3. Can I get both vaccinations at the same time?

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 injections.

4. Are there any side effects from the vaccines?

All vaccines have side effects, and this also applies to the vaccines against influenza and COVID-19.

Some people experience fever, headache or tenderness at the injection site. These are completely normal side effects that go away on their own.

It is very rare for someone to have a severe allergic reaction after vaccination.

If you have previously had a severe allergic reaction after a vaccination or after an injection with another medicine, you should talk to a doctor before getting vaccinated.
