ObjectiveThe aim of the study was to assess efficacy of current vaccination programs. MethodsWe evaluated the routine annual vaccination programs implemented by the Government of Mali against Contagious Bovine Pleuropneumonia (CBPP) in cattle and Peste des Petits Ruminants (PPR) in small ruminants in selected communes of Mopti and Sikasso regions in 2016. Serum samples were collected before and after vaccination from randomly selected 1500 cattle and 1500 small ruminants. C-ELISA was used to measure the level of sero-conversion of animals following vaccination.

Herd immunity cannot be achieved with the current vaccination strategies. Post vaccination sero-monitoring is a useful tool  to assess performance of vaccination campaigns RecommendationsTo improve vaccination programs, there is need for participation of all stakeholders, and close engagement of government agents with actors such as private veterinarians to ensure that their investment in vaccination campaigns results in the expected returns, p.e. having effective protection against target diseases.Vaccination of cattle by a animal health worker in Sikasso regionResultsLimited increase in herd immunity after vaccination was observed for both diseases:Michel DioneInternational Livestock Research Institute Burkina Faso, West Africa (m.dione@cigar.org)The 15th International Symposium of Veterinary Epidemiology and Economics, 12-16th November 2018, Chiang Mai, Thailand.
