Immune system and influenza virus
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2015, Vol 69, Issue 0
Abstract
Influenza viruses are a significant cause of respiratory infections, causing 3-5 million clinical infections and 250-500 thousand deaths per year. Infections caused by the influenza virus induce a host immune response at the non-specific and specific level (defined as natural and acquired), which leads to limitation of virus replication. Moreover the elements of immunological memory are induced so that they can protect against subsequent infection by the influenza virus. However, there is still no effective way for the total elimination of this virus, and the only effective method to combat this pathogen appears to be vaccination, which through immune system activation greatly limits its spread.The present paper presents the immune reaction at different levels in response to the influenza virus after entering the body and the mechanisms of the influenza virus for avoiding reactions of the immune system, which correspond to its high variability at the molecular level. Moreover, in this paper we describe various methods of stimulating the organism’s immune systems with different generations of vaccines and their effectiveness in the fight against this pathogen.
