title: A coordinated strategy for evaluating new vaccines for human and animal tuberculosis.
abstract: There is a remarkable convergence in the current efforts to develop and evaluate new tuberculosis (TB) vaccine candidates for use in humans, domestic animals, and wild animal reservoirs. It is quite likely that similar vaccination strategies will prove useful in these diverse host species. Many TB vaccine candidates are being screened for protective efficacy in conventional laboratory animals (e.g. mouse, guinea pig), in captive wild species under laboratory conditions (e.g. brushtail possum), and in the target hosts (e.g. cattle, deer). These systems share some important features, e.g. direct challenge infection of the lung by intratracheal or aerosol exposure, and the use of bacterial enumeration, and gross and microscopic histopathology, as the readouts. Some TB vaccine candidates have been tested in many models, yielding important insights into common mechanisms of resistance to Mycobacterium tuberculosis and M. bovis, and providing evidence of the vaccine's ability to induce protection under widely different circumstances. Coordination of this global search for better TB vaccines, irrespective of target species, would facilitate the rapid application of new technologies and maximize the sharing of materials and experiences between human and veterinary TB researchers. The creation of liaisons between TB vaccine research efforts of government-sponsored medical and agricultural research programs, international bodies such as the World Health Organization (WHO) and the European Community (EC), private foundations and the vaccine industry, will yield a high return.
