China's research on bird flu vaccine is now the most advanced in the world, said experts attending an ongoing conference in Kunming aimed at strengthening cooperation on controlling the highly pathogenic avian influenza (HPAI) in Asia.
The H5N1 bird flu vaccine developed by China has been proved "effective" after being used in some Southeast Asian countries, according to the experts who are here to participate in a Ministerial Conference for Asian Cooperation on HPAI Control.
The vaccine can be applied to chickens and water fowls, they said.
China's Ministry of Health on Tuesday night confirmed a new case of human infection of bird flu in Ziyuan County, south China's Guangxi Zhuang Autonomous Region.
Previously, China reported three human cases of bird flu and one suspicious case.
