Administer by subcutaneous injection in upper neck observing aseptic precautions. All breeding sheep must receive two 2ml injections separated by an interval of 4-6 weeks. In adult breeding ewes, the second 2ml dose should be administered 4-6 weeks prior to lambing. Lambs being retained for fattening or subsequent breeding will require a full course of vaccination. At a minimum age of 3 weeks these lambs should receive two 2ml injections separated by an interval of 4-6 weeks. A 2ml booster injection should be given no longer than 12 months after their last vaccination. In adult breeding ewes these yearly booster injections should be given 4-6 weeks prior to lambing. On farms where the incidence of pasteurellosis is high, a supplementary 2ml booster injection using Ovipast Plus may be required 2-3 weeks prior to expected seasonal outbreaks.
