Several cases of infection have been detected after vaccination against coronavirus. This is presented by data from the National Vaccination Registry (SYSVAK) and the Infectious Disease Notification System (MSIS). In total, over 296 thousand. people were vaccinated with two doses of the vaccine by April 12, of which 199 people (0,07%) were diagnosed with coronavirus. Norwegian Institute of Health The National Institute of Public Health (NIPH) is conducting a review of vaccinated people who have nevertheless been diagnosed with the virus in Norway.
The degree of protection may vary with different vaccines and other factors
. Covid-19 vaccines provide the vaccinated person with good protection against serious disease. Full protection is achieved 1-2 weeks after the last dose of the vaccine. The degree of protection may vary depending on the different vaccines, and individuals may have different immune responses to the same vaccine depending on their age and health status.
Vaccines never offer 100% protection against the infection of the disease you are vaccinated against
- Vaccines never offer 100% protection against the infection of the disease you are vaccinated against. This means that even if a person has been fully vaccinated against the coronavirus, the coronavirus (SARS-CoV-2) can be detected in that person, explains department director Karianne Johansen in the FHI infection control registries.
Most vaccinated people and those infected with the Covid-19 coronavirus have milder symptoms with a shorter duration than unvaccinated people. The vaccine protects against the severe course of coronavirus infection that requires hospital treatment.
Positive cases of fully vaccinated people are further monitored through information gathering
The presence of coronavirus in fully vaccinated people can be detected by combining vaccination information in SYSVAK with positive covid-19 test results reported to MSIS. Positive fully vaccinated cases are further monitored by collecting information on any mutations in the samples in collaboration with the NIPH reference laboratory.
"Serious illness is rare, but when it does occur, it's important to do more research to understand what might be causing it," says Johansen.
