Is there a vaccine available for Brucella suis?

Brucella suis, a bacterium causing brucellosis in swine and can infect humans, does not have a widely available vaccine for use outside of controlled conditions. While there have been efforts to develop vaccines for Brucella spp., including B. suis, none have achieved widespread acceptance or regulatory approval for public use, particularly in veterinary medicine.

The current vaccination strategies primarily target other species of Brucella, such as B. abortus for cattle. Hence, the absence of an effective vaccine for B. suis in typical veterinary practice leads to the conclusion that there is no available vaccine for this specific bacterium.

This is especially significant because brucellosis is managed more through herd management and testing rather than vaccination. In high-risk areas or populations, individuals may be educated about preventive measures, but no specific vaccine is provided for use in pigs or as a protective measure against B. suis. The nuances of vaccine development and the regulatory environment further underscore the absence of a vaccine currently available.
