Protection against COVID-19 after vaccination or having had COVID-19

Although the coronavirus vaccine provides a high degree of protection against COVID-19 already 3 weeks after the first dose, two doses are necessary for the best possible effect and duration. The vaccine also helps to limit transmission. We do not yet know for sure how long the protection will last. So far, it has been shown that the protection lasts for at least half a year although it probably lasts much longer, more knowledge will become available.

Similarly, we know that it is very rare for someone to be re-infected in the first months after undergoing COVID-19. For the best possible effect and duration of protection, those who have had the disease are recommended to have one vaccine dose.

However, neither the disease nor the vaccine provides guaranteed protection against COVID-19 or against being able to transmit the disease further. Therefore, vaccinated people must also follow the infection control advice that applies at all times and arrange to be tested if you get COVID-19 symptoms. The few who get COVID-19 despite being vaccinated or having undergone the disease will most often have a mild disease course or no symptoms.

Who is considered fully vaccinated and protected, and what is meant by a risk group?

Those who are considered "fully vaccinated" are:

  • Those who have received a second dose of vaccine. Status as fully vaccinated applies from 1 week after the second vaccine dose.
  • Those who have had COVID-19 and at least 3 weeks later have received a dose of vaccine. Status as fully vaccinated applies from 1 week after the vaccine dose.
  • Those who received the first dose of vaccine and then, at least 3 weeks later, were diagnosed with COVID-19 infection. Status as fully vaccinated applies from the time you are out of isolation.

If the protection decreases over time, the advice may change. This may lead to recommendations for a booster vaccine.

Those who are considered to be “protected” are:

  • Those who are fully vaccinated (see above).
  • Those who have received their first vaccine dose. Status as protected applies from 3 to 15 weeks after the vaccine dose. This means that the second dose must be given no later than 14 weeks after the first dose in order to maintain a protected status until you are considered fully vaccinated.
  • Those who have had COVID-19. Status as protected is valid for 6 months after the positive test result.

The definitions related to vaccines apply to those who have received vaccines approved by the European Medicines Agency (EMA). All vaccines given in Norway are approved by the EMA.

Those covered by the term "risk group" are:

  • People 65 years or older
  • People from the age of 18 with certain defined diseases / conditions that increase the risk of severe disease course and death from COVID-19 (medical risk groups).

What advice applies at home?

  • In private homes and cars, protected people can have close social contact (less than 1 metre) with other protected people, even if they are in a risk group.
  • Protected people may have close social contact with unprotected people who are not in a risk group.
  • Protected people should still keep a good distance (at least 1 metre) from unprotected people in a risk group with whom they do not live.
  • Protected people can be treated as household members and do not need to be counted as visitors. Unprotected visitors must still keep their distance from other unprotected people.
  • If you live in a municipality with regulations on how many people can visit private homes, you must follow this.

Which advice and rules apply in public?

  • Protected people are no longer advised against making unnecessary journeys in Norway. However, the general advice on the journey is to keep your distance and wear a face mask.
  • Out among people (in public, including public transport) the advice and rules are unchanged. This applies, for example, to advice and rules on distance, number, hygiene and the use of face masks.

Which quarantine rules apply to those who are considered to be protected?

There are different types of quarantine:

  • Entry quarantine - after being abroad
  • Infection quarantine - after close contact with a person infected with coronavirus
  • Waiting quarantine - temporary quarantine for people who live with someone who is in infection quarantine. Lasts until the person in infection quarantine has tested negative or the person in waiting quarantine has tested negative.

Quarantine exemptions for vaccinated people:

  • Infection quarantine:
    o Fully vaccinated people are exempt from infection quarantine that would otherwise apply to close contacts of an infected person.
    o Those who are considered "protected" can also be exempt if they take a PCR test between days 3 and 7.
  • Waiting quarantine:
    o Exemptions if the household member in infection quarantine and / or the household member in waiting quarantine was vaccinated at least 3 weeks ago ("protected")
  • Entry quarantine:
    o Exemptions for healthcare personnel from abroad during working hours if strictly necessary for critical societal function (§ 6e third paragraph), subject to a negative test on arrival in Norway.
