Questions about vaccines

Updated: 11 May 2022

You are entitled to free vaccination in Denmark, if:

  • You are registered as residing in Denmark.
  • You live abroad but are covered by health insurance in Denmark (you have a special Health Insurance Card).
  • You are temporarily resident in Denmark, but are not covered by health insurance in Denmark.

However, health authorities do not offer vaccination to children under the age of 5, as the vaccines have not been approved for this age group.

Yes, if you are yet to start your vaccination you can chose between Pfizer/BioNTech (Comirnaty) or Moderna (Spikevax), which are the two vaccines offered in the danish vaccination programme.

Once you have had both of your vaccinations, you should expect to have the maximum protection of Pfizer/BioNTech’s Comirnaty after 7 days. Spikevax from Moderna provides maximum protection after 14 days. Vaxzevria from AstraZeneca® provides maximum protection 15 days after the second dose.

It is important that you follow the recommended intervals between the two vaccinations to get the maximum protection.

Vaccination using the vaccine from Johnson & Johnson is given in a single dose and provides maximum protection after two weeks.

You cannot be vaccinated while you have COVID-19, but you can be vaccinated if you have had COVID-19. However, we recommend that you wait to be vaccinated until one month after you are no longer ill.

If you are waiting for a test result about suspected COVID-19, or because you are a close contact of someone infected, we recommend that you postpone the vaccination until you have received a negative test result. If you are waiting for a test result for other reasons, you may be vaccinated.

In general, we do not recommend that people are routinely tested for COVID-19 before vaccination.

All vaccines, including the COVID-19 vaccines, can have side effects. In general, these are mild and short-lasting side effects, and the authorities consider the vaccines to be very safe and well-documented.

Most people experience some pain where they are injected. Other common side effects include fatigue, headaches, muscle and joint pain, chills, a slight fever, and redness and swelling at the injection site. These are generally signs that your body’s immune system is reacting as it should to the vaccine. You do not need to call your doctor if you experience these known and short-term side effects.

In rare cases, severe allergic reactions (anaphylaxis) may occur, caused by e.g. allergy to something in the vaccine.

If you have previously had a severe allergic reaction after receiving a vaccine or injection, you should contact your doctor before you are vaccinated against COVID-19. If you have a known allergy to macrogols/PEG/polyethylene glycol, you should not be vaccinated with Comirnaty from Pfizer/BioNTech, Spikevax from Moderna or Vaxzevria from AstraZeneca. Emergency staff will always be on hand to deal with rare allergic reactions at the COVID-19 vaccination centres.

From other vaccines, we know that almost all vaccination side effects occur within the first six weeks of being vaccinated. It is very rare for them to occur later. Both the Danish and European medicines agencies monitor vaccines closely after they have been approved, both in terms of how well they work and how many side effects they cause.

Right now, it appears that the approved vaccines are helping to reduce the spread of infection. Therefore, some infection prevention measures will gradually be phased out for those who have been fully vaccinated.

It is not yet known how long the vaccines provide immunity for. The health authorities are following developments and research closely, and adapting the recommendations as we learn more about the vaccines and how effective they are. 

The recommendation is that you follow the guidelines in public spaces, even if you are fully vaccinated.

The Danish Health Authority expects the vaccination program to return in the fall because, based on previous experience, we expect COVID-19 to be a seasonal disease. This means that the disease most likely flares up in fall and winter, just as we know it from, for example, influenza. Therefore, a new vaccination program against COVID-19 may be necessary at a later stage.

The Danish Health Authority recommends that you complete your started vaccination series. That is, if you are missing your 2nd dose, you are recommended to take it, and if you are invited to your 3rd dose, you are also recommended to take it. This applies regardless of whether you have been infected with COVID-19 between doses.

If you have had COVID-19 between your vaccinations, we recommend that you wait until 1 month after you have recovered.

It is expected that the general population over the age of 18 is well protected against a serious course of illness and hospitalization with COVID-19 after the 3rd dose, and that people under the age of 18 are well protected after the 2nd dose. This does not mean that you cannot become infected with COVID-19, as vaccination has a lower effect on the spread of infection with the omicron variant, but as vaccinated you are well protected from a serious course of illness.
