Understanding Bovilis Vision 8 with Spur can be crucial for livestock owners aiming to safeguard their animals from devastating clostridial diseases. This article provides a detailed overview of this vaccine, addressing key aspects like its efficacy, administration, and important safety precautions.
Bovilis Vision 8 with Spur is a multivalent clostridial vaccine designed for healthy cattle and sheep. It offers broad-spectrum protection against a range of serious clostridial diseases that can cause significant losses in livestock. This means it tackles several disease-causing bacteria simultaneously, simplifying vaccination protocols.
The inclusion of SPUR®, a proprietary adjuvant technology from Intervet, enhances the vaccine’s effectiveness. Adjuvants act as a booster for the immune response, helping the animal’s body develop stronger and more durable immunity against the targeted clostridia. This is a key feature contributing to the vaccine’s overall efficacy.
Diseases Prevented by Bovilis Vision 8 with Spur
This vaccine targets several dangerous Clostridium species:
Clostridium chauvoei (Blackleg): Characterized by sudden death and characteristic muscle swelling.
Clostridium septicum (Malignant Edema): Causes severe swelling, often accompanied by gas formation and a foul odor.
Clostridium haemolyticum (Bacillary Hemoglobinuria/Red Water): Leads to red-colored urine and often results in sudden death.
Clostridium novyi (Black Disease): Causes liver necrosis and sudden death, frequently observed in sheep.
Clostridium sordellii: Can cause various infections, often with serious complications.
Clostridium perfringens Types C and D (Enterotoxemia): Causes severe enteric (intestinal) disease, particularly in young animals.
The wide range of clostridial species covered by Bovilis Vision 8 with Spur makes it a valuable tool in preventative healthcare for livestock. This comprehensive approach minimizes the risk of multiple infections, simplifying herd management and improving overall animal health.
Bovilis Vision 8 with Spur is administered subcutaneously (under the skin) with a single 2 mL dose. A two-dose vaccination schedule is generally recommended, with the second dose given 3-4 weeks after the first. This two-dose regimen ensures optimal immune stimulation and protection.
While the product was licensed before minimum age requirements were mandated, consulting your veterinarian is crucial, especially for young or vulnerable animals. They can advise on the appropriate timing and frequency of vaccination based on your specific herd’s needs and risk factors. The duration of immunity isn’t definitively established, making regular veterinary consultation essential to determine revaccination schedules.
Revaccination and Duration of Immunity
Revaccination frequency depends on several factors, including the risk of exposure to the targeted Clostridium species. Annual revaccination is generally recommended for comprehensive protection. However, for animals at high risk (those frequently exposed to contaminated environments, for example), more frequent revaccination (every 5-6 months) may be necessary. Your veterinarian can help to tailor a revaccination schedule to your specific circumstances.
Storage and Handling
Proper storage is crucial to maintain the vaccine’s potency. Bovilis Vision 8 with Spur should be stored refrigerated between 2°C and 8°C (35°F and 46°F). Freezing is strictly prohibited, as it can compromise the vaccine’s efficacy. The entire contents of the vial must be used after opening. This prevents contamination and ensures consistent potency for all doses.
The vaccine is available in 20 mL (10 doses) and 100 mL (50 doses) vials. Needles and syringes are sold separately. Remember to shake the vial vigorously before and during use to ensure the vaccine’s even distribution and optimal effectiveness.
Allergic Reactions: As with any vaccine, allergic reactions are possible. In case of any allergic reactions (requiring epinephrine treatment) or human exposure, seek immediate medical attention.
Withdrawal Period: A 21-day withdrawal period is required before animals can be slaughtered for consumption. This ensures the safety of the meat supply.
Pregnancy: The safety of Bovilis Vision 8 with Spur in pregnant animals has not been tested. Consult your veterinarian before vaccinating pregnant animals.
Mixing: Do not mix this vaccine with other products.
Veterinary Consultation: Always consult with your veterinarian before administering this vaccine or making decisions related to your herd’s vaccination schedule. They can assess your herd’s specific needs and recommend the most appropriate vaccination program.
Bovilis Vision 8 with Spur, incorporating SPUR® technology, represents a significant advancement in clostridial disease prevention for cattle and sheep. By understanding its application, limitations, and safety precautions, livestock owners can effectively utilize this vaccine to protect their herds and minimize potential economic losses. Remember, consistent communication with your veterinarian is key to ensuring optimal herd health and maximizing the benefits of this valuable tool.
