Re: General Indonesian BF news
Snip of news, regarding vaccination in Indonesia and a-symptomatic chickens; not new but may be worth repeating.
July 2007
The vaccine does not kill the virus, it only weakens it. However, up to a week after vaccination the virus is still carried in poultry feces,? said M. Zoelkarnain Hasan, head of public communication affairs for the Avian Influenza Control Unit at the Agriculture Ministry.
It is estimated that birds vaccinated only once can still carry up to 45 percent of the virus in their feces. ?It?s important that we are aware that those poultry need to be re-vaccinated two to three times,? he added.
This is referred to as the shading phenomena, in which healthy poultry are able to carry the virus. Hasan said intense vaccination and regular cleaning of poultry farms are the most effective preventative measures.
