Vaccines and prophylaxis for food producing animals

Vaccination for food producing animals is a fast evolving field. The evolut ion in this field is not only due to scientific and technical progresses, b ut also to a different, more epidemiological, approach of vaccination. Vacc ination for food producing animals did also broaden its perspectives; in so me cases, the aim of vaccination is more to protect human health than anima l health. Finally other aspects are taken into consideration, such as anima l welfare, protection of consumers and environmental protection. The proble m of bacterial resistance to antibiotics may partly be solved by the coming back of preventive vaccination.
