In economic and epidemiological terms, the practice of culling on farms within a radius of 1 to 3 km of infected farms is the best method of combating Highly Pathogenic Avian Influenza (HPAI). Vaccinating chickens within a radius of 3 km of an infected farm may at first appear to be cheaper, but it is less effective because the epidemic spreads further and lasts longer. This was one of the findings of a study performed by LEI together with the Central Veterinary Institute (CVI), both part of Wageningen UR.
