Intensification of animal food production and emergence of new production systems (such as Raised Without Antibiotics or organic systems) has resulted in emergence or re-emergence of pathogens. These new societal trends, together with the willing to reduce the use of antimicrobials in livestock productions, highlight the importance of improving existing vaccines and/or development of new vaccination strategies to fight against emerging or re-emerging pathogens.
