After you have been vaccinated or have had COVID-19

Vaccination and having had COVID-19 give good protection, but provides no guarantee against becoming infected (again) and infecting others. Here is a description of what is meant by being partially and fully vaccinated, and the advice and rules that apply to these groups.

Vaccination and having had COVID-19 give good protection, but provides no guarantee against becoming infected (again) and infecting others. Here is a description of what is meant by being partially and fully vaccinated, and the advice and rules that apply to these groups.


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

Although the coronavirus vaccine provides good protection against COVID-19 already 3 weeks after the first dose, two doses are necessary for the best possible effect and duration of the vaccine. The vaccine also helps to limit transmission. We do not yet know for sure how long the protection will last. The data and information we have show that the protection lasts for at least a year, although it probably lasts longer.

Those who have had the disease are recommended to have one vaccine dose, for the best possible effect and duration of protection.

However, neither the disease nor the vaccine provides guaranteed protection against being infected with 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. Persons who are fully vaccinated and who do not have any symptoms do not normally need to get tested. 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. Vaccinated people must still be in isolation with confirmed COVID-19, and their close contacts should follow the advice for close contacts.

Who is considered fully vaccinated and partially vaccinated, 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 received a single-dose vaccine, with effect from 3 weeks after vaccination.
  • 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 the person is out of isolation.
  • Those who have confirmed antibodies to SARS-CoV-2 by an approved laboratory method (with an antibody serology in a microbiological laboratory), and received one vaccine dose. The vaccine dose may be given the same day at the earliest. Status as fully vaccinated is valid 1 week following vaccination. 

If the protection decreases over time, the advice may change.

Those who are considered “partially vaccinated” are:

  • Those who have received the first dose of a vaccine (in a multi-dose regimen) at least 3 weeks ago.

The definitions related to vaccines apply to the following vaccines against COVID-19:

  1. Vaccines that have a marketing authorization in Norway,
  2. CoronaVac and
  3. Covishield.

Those covered by the term "risk group" are:

  • Persons who are 65 years or older
  • Persons 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).
  • See: Risk groups and their relatives

Information on the advice that applies if you get new-onset respiratory symptoms can be found in the article What should you do with newly-arisen respiratory tract symptoms?

What rules for entry quarantine apply to people who are fully vaccinated or have had COVID-19?

  • Fully vaccinated and persons who have had COVID-19 in the last 6 months are exempt from the entry quarantine requirement.

Currently, only presentation of a COVID-19 certificate with a QR code which can be verified by the Norwegian authorities is considered a secure and verifiable way to document vaccination or previous illness. Here you will find more information about the COVID-19 certificate and which COVID-19 certificates are accepted:
