Sharp recent increases in helminth disease frequency and/or intensity have been reported in ruminants in some parts of the EU. Climate change has been proposed to be linked to these observations.
If such patterns continue as predicted, EU farmers may have challenges with helminth infections never encountered before.
Against this background, the economic impact of helminth disease has become an increasing issue in the livestock sector where profit margins can be low.
This, coupled with anthelmintic resistance and consumer concerns regarding chemical residues in food and their detrimental impact on the environment, indicate that alternative approaches to helminth control (such as vaccines) are an urgent requirement.
