Rift Valley Fever Live 100X1ml
Freeze-dried, live attenuated Rift Valley fever virus (Smithburn strain) for the immunisation of cattle, sheep and goats against Rift Valley fever
RECOMMENDATIONS FOR USE
Animals can be vaccinated at any age except that lambs, calves and kids from immune animals should not be inoculated before they are six months old because maternal antibodies may block the vaccine response. This disease occurs during the late summer and autumn and it is, therefore best to inoculate susceptible animals during spring, three to six weeks before the mating season. Where possible, breeding should also be arranged so that ewes lamb from February to April to ensure that lambs will be adequately protected by maternal antibodies
during the time of the year that this disease occurs. Annual vaccination is recommended.
Cattle, sheep and goats: 1 ml subcutaneously
