Leptavoid HB9000033

For Leptavoid H the dose program consists of two 2ml injection under the skin, with a 4 week interval between doses. Animals must be at least 1 month old before they can be dosed. Shake well before use to mix the contents before extracting the vaccine. The subcutaneous injection should be administered in loose skin covering the chest wall, or in the side of the neck. Vaccinated cattle may show positive for diagnostic tests and therefore are unacceptable for movement off farm. The vaccine should not be administered within two weeks of breeding as this may impair conception rates. This may be partly due to stress around breeding rather than a specific vaccine effect. Such effects are minuscule when compared to the conception rates of herds that have a Leptospira hardjo problem. However, it should be considered when timing A.I. especially with valuable semen. Young stock with maternally derived antibody (colostrum) may negate the action of the vaccine. An increase in temperature of 1 to 1.3 degrees Celsius lasting 24 - 48 hours after vaccination has been observed, generally after the second dose. Administration of the first and second dose may produce swellings or lumps in most animals around the administration site. These reactions will resolve over several weeks after administration, but may persist for longer. Local reactions are very common. Hypersensitivity reactions may occur in a small number of cases. If hypersensitivity occurs adrenaline can be administered or consult your veterinary surgeon. This vaccination can be used during pregnancy, lactation or lay. Avoid using vaccinations during periods of stress and it should not be administered within two weeks of breeding. Should be kept in cold storage between 2 degrees Celsius and 8 degrees Celsius. Protect from direct sunlight. Do not freeze. Zero withdrawal period.
