A field trial was carried out in a Maasai homestead to assess the impact of East Coast Fever (ECF) immunisation by the infection and treatment method (ITM) with the Muguga Cocktail on the occurrence of this disease in Tanzanian pastoralist systems These data were further used in partial budgeting and decision analysis to evaluate and compare the value of the control strategy Overall ITM was shown to be a cost-effective control option While one ECF case was registered in the immunised group 24 cases occurred amongst non-Immunised calves A significant negative association between immunisation and ECF cases occurrence was observed (p <= 0 001) ECF mortality rate was also lower in the immunised group However as anti-theilerial treatment was given to all diseased calves no significant negative association between immunisation and ECF mortality was found Both groups showed an overall similar immunological pattern with high and increasing percentages of seropositive calves throughout the study This combined with the temporal distribution of cases in the non-immunised group suggested the establishment of endemic stability Furthermore the economic analysis showed that ITM generated a profit estima
