The University of Queensland has developed an experimental vaccine for bovine trichomoniasis, a disease that leads to infertility in cattle. The disease was found in bulls from all major Australian livestock regions, with losses from reproductive inefficiencies costing the industry between $60 million and $100 million annually. Currently, the use of imported vaccines is often inappropriate due to safety concerns, making a locally produced vaccine necessary. The vaccine has been successfully tested on a small group of bulls, with larger trials planned.
