Campylobacter vaccine is indicated for use in cattle and sheep to prevent reproductive diseases caused by Campylobacter fetus and C. jejuni.

INDICATIONS

• Prevention of Infertility: The main clinical sign of the disease in a herd is an increased number of services per conception, leading to low pregnancy rates and a prolonged calving season.
• Prevention of Abortion and Embryonic Death: Vaccination helps prevent early embryonic death and occasional abortions that can occur at 4 to 6 months of gestation.
• Prophylaxis and Treatment of Infected Animals: The vaccine is used for both prevention in healthy stock and to aid in hastening the elimination of the bacterium in already infected cows, significantly improving their fertility.
• Use in Carrier Bulls: Bulls do not show symptoms but carry and transmit the disease. Vaccination is indicated for bulls as both a treatment and preventative measure to stop the spread, often in conjunction with other management practices like artificial insemination.
• Herd Management: Vaccination is a key tool in the control and prevention strategy for affected herds, often used in conjunction with identifying and culling carrier bulls or using artificial insemination.

ADMINISTRATION

• Route: Subcutaneous (SC) injection, under the skin.
• Location (Cattle): Upper neck.
• Location (Sheep/Livestock): In the fold of skin behind the shoulder (axillary space).
• Technique: Aseptically, using clean, sterilized needles; lift a fold of skin to create a “tent” and inject into the space.
• Dosage: Varies by product (e.g., 2 mL for cattle, 5 mL for sheep/goats). 

• Flexible vaccination program – 1st dose: Up to 8 weeks prior to joining; 2nd dose: 3 – 8 weeks after first dose. Annual booster before joining for previously vaccinated ewes.
• Cattle: A primary 2 mL dose given 30 days to 7 months before breeding, with annual revaccination before breeding.
• Sheep: A primary dose before joining, repeated 3-8 weeks later, with annual boosters before subsequent joining.
