5. Conclusions
The results of our study suggest that future strategies to mitigate vaccination compliance deterioration should be focused on encouraging veterinary organizations to continue and exert social pressures on the farmers to vaccinate. The success of such a strategy probably depends on the existing trust between the farmers and the veterinarians and the robustness of the veterinary infrastructure. Veterinarians can also be the main agents to educate farmers regarding the vaccine and the disease. We also suggest that identifying and helping farmers who have difficulties, either in manpower allocation or vaccine funding, may increase vaccination compliance. Such strategies should be examined in the future and their effectiveness should be critically evaluated. It is also of interest to examine the change in beliefs of the veterinarians themselves as time elapses from an epidemic of LSD as well as of other infectious diseases. These will help to maintain high vaccination compliance along time and prevent the recurrence epidemics.
