 Primary ( sensitising ) Revaccination
 dose dose 
 Sheep & goots 5 ml 3 ml 
 The container should be shaken well before doses are withdrawn.
Administration is by subcutaneous injection . 
An initial course of immunisation is necessary comprising a primary
( sensitizing ) dose and a second dose which creates good immunity . The interval between these doses should be not less than 3 weeks. The primary course should be completed about 2 weeks before maximum immunity is required which may be either a period of high risk or during lambing . lambs born from ewes immunized with polyvalent vaccine two weeks before lambing should be protected untill they are about 8 weeks of age . Because of the presence of maternally - derived antibodies, which may interfere with vaccination, these lambs should not be vaccinated unit they are 8 weeks of age.
 Lambs born from ewes vaccinated with a 5 ml sensitisng dose should not be given their first dose of polyvalent untill they are 10-12 weeks of age, because the extended presence of maternally - derived antibodies may interfere with earlier vaccination . 
Revaccination is required at 6 monthly intervals for continuous protection, but if the risk is seasonal annual vaccination may suffice. 
 Used bottles should be disposed of at the end of each day,s operation, as under field conditions it may be difficult to avoid accidental contamination of the vaccine . 
As with all vaccines occasional hypersenitivity reactions may occur. In such cases appropriate treatment such as adrenalin or antihistamines should be administered without delay .
