 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 The container should be shaken well before doses are withdrawn.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. 
PRECAUTION : 
 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 .
