VacciCost - A tool to estimate the resource requirements for implementing livestock vaccination campaigns. Application to peste des petits ruminants (PPR) vaccination in Senegal
Archive ouverte
Vaccination is one of the main tools currently available to control animal diseases. In eradication campaigns, vaccination plays a crucial role by reducing the number of susceptible hosts with the ultimate goal of interrupting disease transmission. Nevertheless, mass vaccination campaigns may be very expensive and in some cases unprofitable. VacciCost is a tool designed to help decision-makers in the estimation of the resources required to implement mass livestock vaccination campaigns against regulated diseases. The tool focuses on the operational or running costs of the campaign, so acquisition of new equipment or vehicles is not considered. It takes into account different types of production systems to differentiate the vaccination productivity (number of animals vaccinated per day) in systems where animals are concentrated and easy to reach, from those characterized by small herds that are scattered and less accessible. The resource requirements are classified in eight categories: vaccines, injection supplies, personnel, transport, maintenance and overhead, training, social mobilization, and surveillance and monitoring. This categorization allows identifying the most expensive components of a vaccination campaign, which is crucial to design cost-reduction strategies. The use of the tool is illustrated using data collected in collaboration with Senegalese Veterinary Services regarding vaccination against peste des petits ruminants. The average daily number of animals vaccinated per vaccination team was found to be crucial for the costs of the campaign so significant savings can be obtained by implementing training to improve the performance of vaccination teams.
