INDICATIONS
For the vaccination of cattle against leptospirosis caused by L. borgpetersenii serovar Hardjo (Hardjobovis) and L. interrogans serovars Copenhageni (Icterohaemorrhagiae) and Pomona. To prevent the shedding in urine of leptospirae of these serovars, and thus reduce the risk of human leptospirosis infection.

FEATURES
This vaccine is prepared from cultured strains of L. interrogans serovars Hardjo, Copenhageni and Pomona. The vaccine contains formalin killed cultures with thiomersal 0.01% added as a preservative. Each batch of vaccine has been fully tested before issue, and proved to conform to accepted standards of sterility, safety, and potency. Trials have been conducted in New Zealand. In cattle challenged with live cultures of the serovars Hardjo and Pomona, shedding of leptospirae in the urine was prevented by vaccination with LEPTO 3-WAY®.

DOSAGE AND ADMINISTRATION
Shake thoroughly before use. 2 ml by subcutaneous injection, given into the anterior half of the neck, with a further dose of 2 ml given four to six weeks later. All animals then require a single 2 ml booster injection each 12 months.

HERD VACCINATION: To begin a herd vaccination program all animals must be vaccinated in the autumn, with a second dose given 4-6 weeks later. An annual booster dose must be given each autumn. Calves and cows intended for introduction to a herd must receive 2 doses 4-6 weeks apart. This programme is applicable to dairy, and beef herds.

VACCINATION OF CALVES: Early vaccination of calves is advisable to protect against acute leptospirosis (‘redwater’), and to minimise the risk of animals becoming carriers prior to vaccination. A course may begin from 12 weeks of age, but in this case it is essential to administer a booster dose at 6 to 9 months of age, to align with future herd vaccination. In all cases, two doses should be given, 4 - 6 weeks apart, and finishing no later than 9 months of age, and a booster vaccination should be given within 12 months. This may require a further single dose of vaccine to align calves vaccinated out of season (i.e. when young, or in a town supply herd), with the annual herd booster in autumn.

HIGH RISK CALVES: Calves deemed to be at high risk may be vaccinated from as young as 4 weeks of age. However, they must still receive a second dose 4-6 weeks after the first AND where the primary vaccination is completed before 6 months of age, a booster dose at 6 months of age is essential.

INTRODUCED STOCK: In the absence of known prior vaccination, dose twice at a 4-6 week interval. To eliminate possible shedding from animals already leptospirosis infected, a course of dihydrostreptomycin (3 days at 25 mg/kg) is recommended.
