– Influenza A (H1N1) from 2009 has become a regular seasonal flu that circulates regularly. This is the case after an epidemic, and then the virus continues to circulate, "says Birgitte Klüwer adviser in the department of influenza at the Norwegian Institute of Public Health.
When a pandemic broke out, infection was associated with severe illnesses and the worst deaths for some of the certain groups among us. Almost, people crossed the men's house to vaccinate themselves to limit the outburst.
The reason why no one talks specifically about the serious threat of swine flu infection now, is that only the virus still comes to visit. Some have been vaccinated because they have been exposed to the virus before.
"The body learns to protect itself against individual viruses," says Klüwer.
This year's vaccine for risk groups contains components of two types of influenza A and one B, and A (H1N1) is one of these.
