    Lambs need 2 doses:

    • First ‘priming’ dose at marking;
    • Second ‘booster’ dose at weaning


    Previously unvaccinated ewes need 2 doses:

    • First ‘priming’ dose at the time of joiningor scanning
    • Second ‘booster’ dose approximately 4 weeks before the expected date of lambing


    Other classes of previously unvaccinated sheep need 2 doses:

    • First ‘priming’ dose
    • Second ‘booster’ dose 4-6 weeks after


    Previously vaccinated sheep need ‘annual booster’ vaccinations:

    • For ewes vaccinate 4 weeks before the expected date of lambing.
    • This should pass temporary immunity to their lambs in the colostrum, or first milk, to protect them for the first 6 to 8 weeks of their lives.

    Where possible give the annual booster at least 2 weeks prior to the time of maximum risk, e.g. transfer to lush pasture or grain feeding in the case of enterotoxaemia.
