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.

Brucellosis: past, present and future.

Prilozi·2010

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.
