Vaccinations are part of health management. A preventive health program in modern sheep production systems is advisable. High economic return per dollar invested can result from proper flock health management.
Health management is much more than a vaccination program.
Vaccinations themselves are considered for a variety of reasons. These include disease risk management and strict prevention. Vaccinations may also be indicated in situations where management practices other than vaccine administration do not produce optimum health or economic benefits. It is not feasible to outline one vaccination program suitable for all sheep producers. As in other species, recommendations must be made on an individual basis to apply to the various health problems encountered.
