– Influenza A (H1N1) from 2009 has become a regular seasonal flu that circulates regularly. As after the pandemic, the virus continues to circulate, "said adviser Birgitte Klüwer in the influenza department at the Norwegian Institute of Public Health.
When the pandemic broke out, infections were associated with serious illness and worst case deaths for some in some of us. Almost, people crossed men's homes to vaccinate themselves to limit the eruption.
The reason why no one talks much about the serious threat of swine flu infection now, it's just that the virus still comes to visit. Some have gained resilience because they have been exposed to a virus before.
"The body learns to defend itself against individual viruses," Klüwer said.
This year's vaccine for the risk group contains components of two types of A-influenza and one B-influenza, and A (H1N1) is one of them.
