4 CLINICAL PARTICULARS

4.1 Target Species

Cattle from 4 weeks of age.

4.2 Indications for use, specifying the target species

For active immunisation

of cattle to reduce kidney colonisation and shedding of Leptospira borgpetersenii serovar Hardjo type hardjobovis to the extent that no viable organisms can be detected by culture in the urine of vaccinated animals after challenge; a 3 weeks onset of immunity and 12 months duration of protection have been demonstrated by challenge with Leptospira borgpetersenii serovar Hardjo type hardjobovis.
of cattle persistently infected with Leptospira borgpetersenii serovar Hardjo type hardjobovis: to reduce urinary shedding of Leptospira borgpetersenii serovar Hardjo type hardjobovis without clearance of renal colonisation; this effect appears 4 weeks post vaccination and its duration is unknown. The epidemiological significance of the reduced shedding has not been demonstrated.

The vaccination may not prevent abortion in cows in which placental infection has already occurred. 4.3 Contraindications

None.

4.4 Special warnings for each target species

Vaccinated cattle may be positive in diagnostic tests for leptospirosis and therefore unacceptable for export to some countries.

4.5 Special precautions for use

Special precautions for use in animals

None.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Even though animals may have been vaccinated, the risk of transmission of leptospirosis from cattle to their handlers, albeit very much reduced, remains. Appropriate precautions should be maintained at all times and prompt medical advice sought in the event of clinical signs of possible infection.

4.6 Adverse reactions (frequency and seriousness)

A diffuse and oedematous swelling up to 10 cm in diameter, sometimes sensitive to palpation, could occur in up to 40% of animals and can last for up to 66 days after completion of vaccination. The reaction to subsequent vaccinations and the reaction in pregnant animals (see 4.7) are more marked. The injection site reaction may be sensitive to palpation the week following vaccination and may persist as a hard nodule for several weeks.

4.7 Use during pregnancy, lactation or lay

Can be used during pregnancy and lactation. The swelling is more marked in pregnant animals. A diffuse swelling of up to 22 cm in diameter can occur following second injection. This effect is more marked for pregnant animals in their third trimester of pregnancy.

4.8 Interaction with other medicinal products and other forms of interaction

No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.

4.9 Amounts to be administered and administration route

Dose: 2 ml

Administration:

By subcutaneous injection, preferably in the neck. Shake the container well before withdrawing the dose.

Basic vaccination scheme:

2 doses of vaccine separated by a 4 to 6 week interval.

Revaccination scheme:

A single 2 ml dose on an annual basis.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

No adverse drug reactions, other than those listed in Section 4.6, occurred after administration of twice the normal dose. As part of the natural response following vaccination, and following an overdose of twice the maximum dose of the vaccine, a reactive lymphadenopathy in the local lymph node as well as production of a subcutaneous, granulomatous, inflammatory reaction could be visible under the skin for at least 2 months. The total duration of this reaction in the underlying tissues is not known.

4.11 Withdrawal Period(s)

Zero days.

5 PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES

To stimulate an active immunity against Leptospira borgpetersenii serovar Hardjo type hardjobovis.

Vaccination induces humoral antibody response and cell-mediated immunity as measured by serology and gammainterferon production. A marked, statistically significant difference is also seen in the anamnestic response following a single booster vaccination or infection (challenge) 12 months after primary vaccination.

A strong serological cross-reactivity post vaccination has been demonstrated against Leptospira interrogans serovar Hardjo, a closely related species in the same serovar. This was sustained for at least 12 months following primary vaccination, and is also seen in the anamnestic response following a single booster vaccination. A cattle challenge model is not available to document protection.

ATC Vet code: QI02AB03 (Immunologicals for bovidae, inactivated bacterial vaccines, Leptospira).
