Influenza A viruses infect humans and other mammalian and bird species. Since 1997, it has been known that some avian strains were able to infect humans, generally causing a mild disease.The present H5N1 avian influenza outbreak has led to a heightened level of awareness of the scientific and public health officials, not only because of its high mortality, but also because of its potential to trigger a new pandemic. In response to this emerging threat, the international sanitary authorities are developing a wide preparation program, which involving different measures such as the accurate diagnosis of animal and human outbreaks; systematic characterization of circulating strains; elimination of infected birds; mass production of antiviral drugs,and research,development and large scale production of efficacious vaccines. In the last aspect, great effort is being carried out for the improvement of classic vaccines and in the search for alternatives based on new technologies.
