Innovation in the development of a safe Q fever vaccine by electron beam inactivation of coxiella.
Coxiellosis is a serious problem in small and large ruminant livestock farming, caused by the zoonotic bacterium Coxiella (C.) burnetii. The pathogen can lead to significant economic losses due to e.g. increased abortion rates, postpartum behavior and pathogen excretion in the milk, as well as causing increased use of antibiotics due to the treatment of accompanying clinical symptoms.
The COX-SAVE research network is taking up this challenge and is working on the development of a modern vaccine using "Low Energy Electron Irradiation (LEEI)", which should offer long-lasting protection, minimize side effects and thus make an important contribution to animal health management and reduce the use of antibiotics in the context of One Health.
Development of a LEEl-C. burnetii vaccine candidate, focus on irradiation parameters and antigen quality for an effective vaccine.
Detailed investigation of the LEEl-C. burnetii vaccine antigen using modern analytical methods for optimized immune response.
Use of the LEEl-C. burnetii vaccine in sheep and cattle to determine the optimal dosage and to validate the vaccine’s safety.
Investigation of the humoral and cellular immune response after vaccination to confirm the protective effect and efficacy of the vaccine.
Development of an improved Q fever vaccine using LEEI technology.
