Cost-benefit analysis of mass vaccination campaign against H5N1 in small scale production systems in Vietnam. Part I: Economical results in Long An province

Highly Pathogenic Avian Influenza (HPAI) caused by H5N1 virus has become endemic in some
developing countries and millions of birds have been culled with large economical and sociological
impacts. Since the end of the first vaccination campaign in Vietnam limited outbreaks in non-vaccinated
domestic poultry have been reported. However, the virus is still circulating as confirmed by routine
surveillance programs. Vaccination is a useful tool to be used to eradicate the disease, but the
cost-benefit impact of different strategy needs first to be addressed at local level, where implementation
is decided. The aim of this study was to evaluate the cost-benefit impact of Vietnam mass vaccination
program at local level. This poster presents the first step in the cost-benefit analysis: the partial economical analysis of the vaccination within Vietnam provinces.
Only the results in Long An province (South) are presented here.
