Correct Vaccination Technique and Instructions

To minimize carcass damage and to prevent further infection after vaccination, it is important to give careful attention to vaccination technique and hygiene. To avoid carcass damage it is important to:

• Sterilise all needles and metal vaccinator guns by boiling in water for at least 10 minutes before use. If using a plastic vaccinator gun immerse in 500 ml of water plus 20 ml of household bleach (4% w/v available chlorine) for 1 hour. Flush with cool boiled water before use. Avoid the use of strong disinfectants.
• Needles should be sharp and clean, replace frequently (every 20-30 animals).
• Short needles work best. For cattle the recommended maximum size needle is 15 mm x 16 gauge. For sheep the recommended maximum size needle is 15 mm x 18 gauge.
• Avoid injection of animals during wet weather or under dusty conditions.
• Inject animals only under the skin and not into the muscle. This is best achieved by raising a fold of skin and injecting the dose under the raised skin.
• Inject animals high up on the neck, behind the ear.

Storage of Vaccines

It is recommended to store all of the Coopers vaccines in a refrigerator between 2°C and 8°C. Vaccines should be protected from light and used before the expiry date marked on the label. The use of an insulated container is recommended during the day to protect the vaccine. If vaccine is to be hung beside the race, ensure it is on the shady side. Once opened, it is recommended that the vaccine be used up within 24 hours and any remaining vaccine after this time should be discarded.

Resealing Instructions

A partially used pack can be kept for use the next day if the following steps are taken:

1. Unscrew the delivery tube from the vaccine pack
2. Empty the delivery tube and vaccinator by depressing the plunger several times
3. Disinfect the stopper
4. Store the vaccine in the refrigerator

Withholding Periods

All of the Coopers vaccines have a Nil Meat and Milk Withholding Period.

Ultrafiltration Process

All of the Coopers vaccines manufactured at the Global Vaccine Unit undergo a process of ultrafiltration to purify the antigens in the vaccine. This process removes impurities, which helps to minimize site reactions, and maximizes animal immune response.
