Guidance for people who are vaccinated against COVID-19

Once you are vaccinated you will have achieved an excellent level of protection against COVID-19. For this reason, we are able to gradually lift some of the infection prevention measures for those who are now fully vaccinated. This also applies if you are at higher risk of severe illness from COVID-19.



COVID-19 surveillance

Vaccination plays a key role in getting us back to normalcy

As more and more people are fully vaccinated, life will gradually and slowly return to normal. 

We know that the vaccines protect people from COVID-19 – including those at higher risk of severe illness from COVID-19.

Current knowledge also suggests that the approved vaccines against COVID-19 are instrumental in preventing the spread of infection. On this basis, we can now begin cautiously and gradually to lift some of our infection prevention measures for those who have been fully vaccinated. However, we do not yet know how long protection lasts. We continue to monitor scientific research closely and adapt our recommendations to the development. Still, for now, we recommend that even people who are vaccinated continue to comply with our general guidance in public spaces. 

Please continue to follow our top six recommendations

  1. Keep a distance of 2 metres whenever possible and always at least 1 metre. Avoid handshakes, hugs, and kisses on the cheek.
  2. Self-isolate and take a PCR test if you have symptoms of COVID-19.
  3. Open windows and doors and ventilate your home. Avoid being too many people together indoors.
  4. Cough or sneeze into your sleeve.
  5. Remember to wash your hands often or use hand sanitiser.
  6. Clean thoroughly and regularly, especially surfaces that are touched by many people.

What does it mean to be fully vaccinated?

You are considered fully vaccinated 14 days after your last injection, regardless of which vaccine you received.

For those who have been vaccinated or have recovered from COVID-19, immunity to the virus can last at least 8 months. 

The Danish Health Authority continuously updates its assessment of how long you can expect to be immune after vaccination or after recovering from COVID-19.

Please bear in mind that even though you have completed vaccination, you should always self-isolate and get tested if you experience symptoms of COVID-19. No vaccine is 100% effective, and therefore there is a slight risk that you may still become infected and ill from COVID-19.

Recommendations for fully vaccinated people

1. Recommendations for EVERYONE who has been vaccinated 

The added protection that vaccination gives you:

  • allows you to socialise with other fully vaccinated people without keeping your distance or wearing a face mask
  • allows you to socialise with family or close friends who are not vaccinated without keeping your distance or wearing a face mask. However, this does not apply if the person you are with has not been fully vaccinated and is at higher risk of severe illness from COVID-19
  • renders self-isolation unnecessary if you are a close contact of someone who is infected. However, you must still follow the guidance on self-isolation and testing if at any time you develop symptoms of COVID-19 
  • Furthermore, you do not need to go for regular testing.

2. Recommendations for people at particularly high risk

Vaccination provides added protection and reduces the risk of severe illness from COVID-19. Therefore, you do not need to follow the special precautions usually recommended for people at higher risk:

People at higher risk

The additional protection of vaccination allows you to:

  • behave like other fully vaccinated people, and you do not need to take special precautions, for example wear a face mask in private contexts
  • participate in activities where several other people are present, for example attend leisure activities
  • use public transport and go shopping at any time of day
  • return to your usual duties. You no longer have to be reassigned to other tasks. However, you should still not participate in the care or treatment of suspected or confirmed COVID-19-cases, for example in an A&E department or on a COVID-19 ward
  • Furthermore, relatives of someone at higher risk do not have to be reassigned to other tasks – if either the person at higher risk or the relative has been fully vaccinated.

Efficacy of vaccination in people with impaired immune systems

1. Should I be concerned that the vaccine is not efficacious?

The majority of fully vaccinated people with impaired immune systems – including cancer patients – will be protected from severe illness from COVID-19.


2. I have a weakened immune system. Will vaccination profect me?

The majority of fully vaccinated people with weakened immune systems, e.g. cancer patients, will be protected from severe illness from COVID-19.

Some people with a severely impaired immune system experience reduced vaccine effectiveness in general, and thus also from the vaccine against COVID-19. This may be true for:

  • transplant recipients and patients
  • people with haematological diseases (e.g. CLL, some types of lymphoma, etc.)
  • some people with primary immune defects.

The Danish Health Authority recommends that you follow our general guidance on infection prevention, even after being fully vaccinated against COVID-19.

General guidance


3. Should I take an antibody test after I have been vaccinated?

Vaccines activate the immune system, and antibodies and cellular immunity are formed - including memory cells that protect against viruses. Most vaccinated individuals will form antibodies, which can be measured, for example, through an antibody test. However, such a test does not measure the entire immune system’s response to the vaccine and cannot detect cellular immunity. But although antibodies cannot be detected in the blood, it does not mean that the vaccine has not been effective.  

The Danish Health Authority does not recommend routine tests for antibodies in the blood after vaccination against COVID-19.
