Summary
Live vaccines are effective for brucellosis control, offering persistent immunity. Optimizing vaccination strategies and developing better diagnostic tools are key to eradicating this zoonotic disease in livestock.
Area of Science:
- Veterinary immunology
- Infectious disease control
- Zoonotic disease research
Background:
- Brucellosis remains a significant zoonotic disease globally.
- Vaccination is a primary strategy for brucellosis reduction in many regions.
- The development of an ideal brucellosis vaccine is an ongoing pursuit.
Purpose of the Study:
- To evaluate the efficacy of live brucellosis vaccines.
- To explore strategies for minimizing disadvantages of postvaccinal antibodies.
- To advocate for expanded adult animal vaccination and further research into novel vaccines.
Main Methods:
- Review of existing literature on brucellosis vaccines.
- Analysis of live versus inactivated vaccine performance.
- Discussion of diagnostic methods and cell-mediated immunity correlates.
Main Results:
- Live brucellosis vaccines demonstrate superiority over inactivated ones in terms of effectiveness, cost, and duration of immunity.
- Reduced vaccine doses and supplemental diagnostics mitigate issues with postvaccinal antibodies.
- Current correlates of cell-mediated immunity (CMI) are poor predictors of protection.
Conclusions:
- Widespread vaccination, particularly of adult animals, is crucial for controlling brucellosis in natural hosts.
- A live *B. suis* strain 2 vaccine warrants further evaluation, especially for swine.
- Development of reliable methods to measure CMI is needed for improved vaccine assessment.
