You are suggesting a very important topic on disease control in general and PPR in particular, the modalities to administer vaccines. I believe that recommendations on vaccine administration strategies should address the needs of specific productive systems (animal density, husbandry system, flock size, individual animal value, epidemiological status, movement patters, et) and be coherent with the organization of veterinary services, contribute to national or regional disease control strategies, and take into account competencies of livestock owners. Vaccination, like many other veterinary practices, should not be seen only as a way to provide "inputs" into the livestock systems, but also as a mean to generate important epidemiological and socio economic information. In principle livestock owners should be allowed to administer vaccines on their own as long as they are ready to comply with specific guidelines and are ready to report on minimum data on
vaccination, application of quality standards, etc. Ideally vaccine administration strategy should be developed through serious dialogue among different stakeholders and not, as it is very often the case, directed by veterinary authorities that more often than not tend to overlook interests and practices of livestock owners. Furthermore, vaccination strategies should require continuous revision and evaluation, based on sound data.
Kind regards
