Infection-free

Have you been infected with covid-19? This affects when you can be vaccinated, when testing is recommended, and when your corona passport is valid again.

Updated: 8 December 2022

You can find important information regarding being infection-free after having covid-19 below.

Vaccination after infection

Most people become immune in the period after they have been ill with covid-19. Current research indicates the immunity lasts for at least six months.

However, there is no certainty that the immunity an individual receives after having been infected with covid-19 is the same as the immunity you receive when you are vaccinated.

The Danish Health Authority continues to recommend vaccination to some groups to protect against serious illness, hospitalization and death.

Testing after infection

For up to 60 days after you or your child has had a positive PCR test, it is not recommended that you be tested. This is because you can still test positive in this period, even if you have recovered and are no longer contagious.
