China develops new, longer-lasting bird flu vaccine: Ministry BEIJING, Monday (AFP) Chinese scientists have developed a new vaccine that can protect poultry from bird flu for a longer period of time, the ministry of agriculture said as the country braces for the migratory season. Laboratory tests showed the vaccine enables chickens, ducks and geese to fight H5N1, the highly lethal strain of bird flu, three weeks after the flocks are vaccinated, China Daily said. The vaccine provides at least 10 months of protection for chickens and ducks - four months longer than the existing prevention drugs, an official from the epidemic prevention section of the ministry's veterinary bureau told AFP. Geese can be protected for three months. The H5N1 virus can also be deadly to humans and is responsible for 33 human deaths in Vietnam since the end of 2003, including 13 since December 30. Twelve people have also died in Thailand. |
