Abstract Content

The poultry industry has undergone major changes in recent years primarily due to the greater global demand of poultry as a source of protein. Along with this greater volume of poultry associated protein (both meat and eggs) are the need to produce such a commodity without food borne pathogens and antibiotics.

Industrial as well as more traditional operations have increased significantly production parameters leading to expansion, merger, internationalization of producing companies as well as the implementation of much larger production units. This has resulted in a rise in problems of education and availability of the workforce, as well as an increase in the pressure and complication of contagious infectious diseases like Avian Influenza, Infectious Laryngotracheitis, Newcastle Disease, Infectious Bursal Disease and Infectious Bronchitis. For these reasons, new production systems have been introduced with higher level of mechanization and automation, so that vaccinations are forced to fit into the processes, and vaccines requested to answer more sophisticated expectations of the producers.

In the meantime, developments in molecular biology have lead to a much better identification and monitoring of the pathogens as well as to a deeper understanding of their mechanisms of action. New vaccines made from these new technologies have been developed, provided with stronger potentialities compared to the classical ones, and more are expected to come in the near future. The possibilities are numerous so that today, the main obstacles before shifting to a new era in poultry vaccinology come mainly from the persistence of old dogmas attached to classical vaccines, the lack of studies on vaccine induced immunity, and the regulations governing their licensing. Some recent evolution in the US may reveal extremely helpful to achieve this transition.
