Prevalence of animal disease has threatened the husbandry and public health. Vaccination is a key to control various animal diseases. To achieve an effective vaccination strategy, several factors should be given more attention, such as vaccine quality, immunization routine and procedures, and evaluation standard. In addition, effective and definite diagnosis guarantees successful vaccinations. With the development of biotechnology and increase of our understanding of host immune responses, progresses on vaccine and immunology in the veterinary field are accumulated. To share related achievement, exchange our ideas, and speed up the immunological development in veterinary medicine, we invite researchers to submit original research and review articles to this special issue. In addition to veterinary pathogens, viruses, bacteria, and parasites, immunological aspects of microorganisms that can cause zoonotic diseases also fall into the scope of this special issue. Potential topics include, but are not limited to:

• Development and testing of novel diagnostic approaches
• Evaluation of novel vaccines or adjuvant effect on immunization
• Identification and characterization of novel immunotherapeutic molecules to control animal diseases
• Action mechanisms of vaccines or antimicrobial agents
• Identification of host factors mediating innate immune responses.
• Characterization of novel monoclonal antibodies and/or mapping of antigenic sites
• Identification of cellular pathways involved in pathogen-host interaction
• Establishment of animal models for immunological analyses of animal infectious diseases
• Debates on immunology

Before submission authors should carefully read over the journal’s Author Guidelines, which are located at http://www.hindawi.com/journals/jir/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/submit/journals/jir/veterf/ according to the following timetable:
