[Vaccination strategies for contagious bovine pleuropneumonia in Africa].

Contagious bovine pleuropneumonia (CBPP) is regarded as the second most important disease of cattle in Africa. The disease was eradicated from Europe through drastic slaughter campaigns with quarantine and restriction of cattle movements. CBPP was mastered in Australia using these methods combined with vaccination. However, the disease remains endemic in Asia and Africa, where it inhibits livestock farming. In these continents, vaccination is the preferred means of control; the aim is to reduce incidence until complementary disease control measures can be applied. The success of a vaccination campaign depends on four main factors: good planning and good organisation; staff who are well-trained, fully equipped and highly motivated; high quality vaccines; good international co-operation. Vaccine strains recommended for use in Africa are strain T1/44 and its variant T1-SR. To improve the immunogenicity of these strains, the Pan African Rinderpest Campaign (PARC) secured financial support for research into immunostimulating complexes (ISCOM). It is hoped that this technology can improve vaccines, leading to effective eradication of the disease. In the meanwhile, systematic and repeated vaccination is the method of choice against CBPP in Africa.
