Hong Kong plans to introduce a new, more effective H5N1 poultry vaccine, Re-6, to its chicken farms before the end of 2012, according to Ko Wing-man, the city's secretary for food and health.

The vaccine has already been introduced on the mainland and has been successfully registered in Hong Kong.

The government has also adopted other measures to combat avian influenza, including vaccination at local farms, import control and stringent hygiene requirements at wholesale and retail markets, according to Ko. Hong Kong will increase surveillance ahead of the coming winter season, and surprise inspections will be conducted at poultry farms and pet bird shops.
