Ovipast Plus

Ovipast Plus is a suspension for injection for sheep - used for the active immunisation and as an aid in the control of pasteurellosis caused by M. haemolytica and B. trehalosi. The vaccine may be 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.

Onset of immunity: As with most inactivated vaccines, significant levels of immunity cannot be expected until 2 weeks after the second dose vaccine in the primary vaccination course.

Duration of immunity: Evidence of efficacy of the Pasteurella/Mannheimia component was generated in an experimental infection model using Heptavac P Plus and it is not possible to provide duration of immunity information using this system. There are reports that active immunity will last for up to 1 year and that passive immunity will persist for up to 4 weeks after birth in lambs from ewes vaccinated with conventional Pasteurella vaccines.

Vaccinate healthy animals only.

The vaccine should be administered by subcutaneous injection in the lateral side of the upper neck observing aseptic precautions. All sheep not previously vaccinated with this vaccine must receive two injections, each of 2ml, separated by an interval of 4-6 weeks. Thereafter they must receive booster injections at intervals of not more than 12 months.

In adult breeding ewes these yearly booster injections should be given during the pre-lambing period, 4-6 weeks pre-lambing, as an aid in the control of pasteurellosis in their lambs.

On farms where the incidence of pasteurellosis is high, a supplementary booster vaccination with this vaccine may be required 2-3 weeks prior to expected seasonal outbreaks.

Withdrawal Period: 
Zero Days

** Please note - this vaccine must be stored refrigerated between 2C and 8C**
