| On 28 February 2003 an epidemic of fowl plague started in The Netherlands, caused by a highly pathogenic avian influenza virus (HPAIV) of type H7N7. The epidemic started in the ‘Gelderse Vallei’, spread to adjacent areas and to the province of Limburg. During the epidemic, 255 flocks were diagnosed as infected. The epidemic was combated by stamping out infected flocks and pre-emptive culling of flocks within a 1-km radius. Moreover, screening and tracing activities were implemented to enhance the detection of infected flocks. In addition, a transportation ban was enforced. In a further stage of the epidemic, poultry-free buffer zones were created, contacts between different parts of the country were reduced by compartmentalization and large areas were... |

| In The Netherlands a large outbreak of highly pathogenic avian influenza in poultry occurred in 2003. The outbreak has had devastating consequences, from both economic and animal-health perspective. Vaccination of poultry offers a potentially attractive measure to control and prevent outbreaks of highly pathogenic avian influenza. In this paper we discuss, from an epidemiological perspective, the values and limitations of vaccination as a control measure during an outbreak and as a preventive measure in an area at risk. In particular, we will discuss (i) the epidemiological prerequisites that have to be met for a vaccine and vaccination campaign to be effective, and (ii) experimental data that have helped quantifying the effect of vaccination on the... |
