Pasteurella and clostridial diseases are among the most common causes of death in lambs and ewes in Northern Ireland.

In unvaccinated flocks, the risk of disease and death due to either Pasteurella or clostridial disease is present all year round.

Hence it is crucial for sheep farmers to realise that both Pasteurella and clostridial diseases pose an ever present threat.

There are many vaccines such as Bravoxin 10 on the market to protect against clostridial diseases, but there is only one vaccine which protects sheep against both Pasteurella and clostridial disease. This vaccine is Heptavac P Plus.

MSD Animal Health recommends that all sheep receive a primary course of Heptavac P Plus from three weeks of age onwards with an annual single booster injection required thereafter. Ewes should be vaccinated 4-6 weeks pre-lambing to ensure that protection can be passed from the ewe to the lamb via her colostrum. These maternally derived antibodies, when passed to the lamb, provide protection for the first three weeks of a lamb’s life.

To ensure long lasting protection lambs should be vaccinated with Heptavac P Plus at three weeks of age and a second injection should be given four to six weeks later. All purchased sheep should receive a full primary course of two doses of Heptavac P Plus four weeks apart as soon as possible after arrival to ensure protection*.

Minimising mortality and maximising growth rates are key components of any efficient sheep production system. Heptavac P Plus reduces mortality and clinical signs of significant diseases. Heptavac P Plus is the most widely used sheep vaccine on the British market and there are two very good reasons for this: Protection against Pasteurella and protection against Clostridial disease.  

For further information on Heptavac P Plus or Pasteurella please consult your veterinary practitioner, the product SPC or MSD Animal Health.
