How are bird flu strains becoming resistant?

One of the great questions facing researchers is how the bid flu becomes resistant to any available medicine. A National Geographic article looks at this phenomenon.

The article discusses Fujan-like, a new strain of the bird flu. It has become resistant to vaccinations of chickens. Â

Yi Guan, director of the State Key Laboratory of Emerging Infectious Diseases at the University of Hong Kong in China, says:

“This novel variant may have become dominant … because it was not as easily affected as other strains by the avian vaccine used to prevent H5 infection.”

This news is very unsettling since the Chinese have been aggressive about vacinating their chickens. With the 2008 Olympics coming up, it’s important for China to get a handle on this.Â
