Msd Ovipast Plus 100Ml (2Ml Dose)

Target species Sheep. Indications for use For the active immunisation of sheep as an aid in the control of pasteurellosis caused by M.haemolytica and P.trehalosi. The vaccine maybe used as an aid in the control of pneumonic pasteurellosis in sheep of all ages from a minimum age of 3 weeks and in the control of systemic pasteurellosis in weaned fattening and breeding sheep. The vaccine may be used in pregnant ewes as an aid in the control of pasteurellosis in their lambs provided that the lambs receive sufficient immune colostrum during the first 1-2 days of life. Contraindications None. Special warnings for each target species The nutritional and metabolic status of pregnant ewes is extremely important at the time of vaccination. If in doubt, advice should be sought from a veterinary surgeon. The vaccine contains an adjuvant and, as with most adjuvanted vaccines, may result in small transient injection site reactions possibly lasting for up to 3 ‑ 4 months after vaccination. Special precautions for use In any group of animals, a small number of individuals may fail to respond to vaccination as a result of immunological incompetence. Satisfactory immune responses will only be attained in healthy animals, thus it is important to avoid vaccination of animals which have intercurrent infection or metabolic disorder. As with most killed vaccines, significant levels of immunity cannot be expected until two weeks after the second dose vaccine in the primary vaccination course. When handling sheep, stress should be avoided, particularly during the later stages of pregnancy when there is a risk of inducing metabolic disorders which may lead to abortion. Operator warnings The vaccine bottle must be shaken well before use. Do not freeze. Syringes and needles must be from gamma-irradiated packs or freshly sterilised by boiling for a least 20 minutes. No alcohol or other disinfectants should be used for sterilisation. The use of an automatic vaccinator is recommended. Since the bottle is non-collapsible, a vaccinator with a vented draw-off spike or similar device must be used. The instructions supplied with such equipment should be noted and care should be taken to ensure the delivery of the full dose, particularly with the final few doses from the bottle. Partly used packs must be destroyed at the end of a day's operations, as re‑puncture of the rubber cap could cause contamination of the remaining contents. Adverse reactions The vaccine contains an adjuvant and, as with most adjuvanted vaccines, immunisation may result in temporary swellings at the injection site. Typically, these swellings may be warm when compared to the surrounding area for up to 14 days after vaccination. Safety studies in lambs have shown that the swellings did not appear to inconvenience the animals or hinder neck movement. As with all vaccines, occasional hypersensitivity reactions may occur. Use during pregnancy or lactation Ewes may be vaccinated during pregnancy as an aid in the control of pasteurellosis in their lambs provided that the lambs receive sufficient immune colostrum during the first 1-2 days of life. Interactions No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.
