The vaccine was made using gene engineering methods. It will shortly be tested for its ability to protect humans. In recent years epidemics of bird flu in poultry have been registered in Cambodia, China, Indonesia, Japan, Laos, S. Korea, Thailand, Vietnam, Turkey and Romania.
Over the past 8 years bird flu killed from 150 to 200 million of poultry – human civilization has never before faced an epidemic of poultry of such proportions.

In 71 cases the infected person died, according to World Health Organization statistics.
