For the active immunisation of susceptible breeding female sheep as an aid in the prevention of abortion caused by Chlamydophila abortus infection. Dosage and administration
The vaccine is reconstituted with the solvent immediately prior to use, allowing 2 ml of diluent per dose. If using the vented transfer device push one end of the device through the centre of the vaccine vial using a firm, twisting action. Similarly, push the solvent vial onto the opposite end of the device taking care to ensure the spike penetrates the centre of the vial bung. Carefully allow diluent to flow into the vaccine vial without completely filling it. Ensure the powder plug is fully dissolved and then invert until all the vaccine solution drains into the diluent vial. Remove the empty vaccine vial and transfer spike from the diluent vial and place into an appropriate disinfectant solution. Alternatively, remove approximately 5 ml of the solvent from the vial with a syringe and needle, inject into the vaccine vial and shake well until the powder plug is fully dissolved. Remove the vaccine solution from the vial, reinject into the diluent vial and shake well. Great care should be taken not to generate an aerosol.
Dose: 2 ml by intramuscular or subcutaneous injection. Ewe lambs, where it is intended to breed from them, may be vaccinated from 5 months of age. Shearlings and older ewes should be vaccinated during the 4 month period prior to mating.
To minimise the risk of self-injection the vaccine should be administered using disposable automatic syringes fitted with a guarded needle system according to the manufacturer's instructions. It is vital that a vented draw off tube is used with this equipment. Regular checks should be made to ensure the syringes are properly calibrated. Carefully attach the vial of reconstituted vaccine to the injection equipment and avoid creating aerosols during the priming process. It may be advisable to wear a visor while carrying out this operation.
