China to launch new bird flu vaccine for poultry

The new vaccine -- 1 billion shots of which are expected to have been produced by year-end -- will be used alongside existing vaccines from next year, the China Daily said, quoting chief veterinarian Jia Youling. 

The live vaccine, which will also work against another poultry disease, Newcastle disease, can be delivered orally, nasally or by spraying and will cost a fifth of existing inactivated vaccines, the newspaper said.
