– Influenza A (H1N1) has become a regular seasonal flu since 2009, which circulates regularly. This is the case after a pandemic, then the virus continues to circulate, ”says adviser Birgit Kleuver in the flu department at the Norwegian Institute of Public Health.
When a pandemic broke out, the infection was associated with serious illness and worse deaths for some of the groups among us. Almost people crossed the house of men to vaccinate themselves to limit the eruption.
The reason that no one talks specifically about the serious threat of swine flu infection is because the virus is still visiting. Some of them were resistant because they were previously exposed to the virus.
“The body learns to defend against individual viruses,” says Kluver.
This year, the vaccine for risk groups contains components of two types of A-influenza and one B-influenza, and A (H1N1) is one of them.
