Reasons to use Leptavoid-H

  • Leptavoid-H is the only licensed vaccine that protects against both strains of leptospiia hardjo
  • Leptavoid-H is the only licensed vaccine that protects against L. interrogans hardjo. This infection was found in 76% of abortion and reduction of milk production
  • Leptavoid-H and Bovilis BVD are licensed for concurrent use.
  • Zero withdrawal times 

Leptospirosis in cattle

In a study carried out Eoin Lynch MVM it was found that 95% of all beef herds and 76% of all dairy herds have been exposed to leptospirosis infections and if an infection reaches an unvaccinated herd the effects can be severe. He advises that all herd owners should take action in the fight against this infection.

What are the signs of a Leptospirosis infection.

  • Reduction in milk produced
  • Abortion which can occur in the late stages of pregnancy
  • Low conception rates
  • Weak calves are born
  • High temperatures in cattle
  • Flaccid, empty udders
  • Sudden drop in yield 

How do herds become infected with Leptospirosis?

Leptospirosis is mainly spread through urine, this means all grazing cattle are in danger of becoming infected. The infection can spread where cattle drink from a natural water source such as a river running through land.  Buying in unvaccinated cattle can bring the infection to your herd. The use of a stock bull can spread the infection. Sheep if co-grazing with cattle can spread the infection without showing any signs of infection themselves.

Vaccination with Lepatvoid-H can increase conception rates.

Another study has shown that cattle vaccinated with Leptavoid-H have a higher conception rate at first service. Herds were divided into two groups, one group was vaccinated and the other was not. The conception rate in vaccinated groups was 51% where the conception rate in the un-vaccinated group was 31 %

Features of Leptavoid-H

  • injectable vaccine
  • For use on both beef and dairy cattle

4.1 Target species 

4.2 Indications for use, specifying the target species 
For the active immunization of cattle from 1 month of age against Leptospira interrogans serovar hardjo and Leptospira borgpetersenii serovar hardjo. 
To reduce shedding of Leptospira interrogans serovar hardjo in urine. 
To improve herd fertility when infertility is diagnosed as caused by Leptospira hardjo.

Circulating antibody is detectable 14 days following the first injection and persists for 12 months following completion of the primary course. Conjunctival challenge demonstrates 12 months cross protection against Leptospira borgpetersenii serovar hardjo(hardjo Bovis). In addition to circulating antibody response, vaccination with Leptavoid-H also stimulates cell-mediated immunity toLeptospira borgpetersenii serovar hardjo which is maintained for at least five months and responds in the event of a challenge five months post vaccination.

4.3 Contraindications

4.4 Special warnings for each target species
Vaccinated cattle may be positive for diagnostic tests and therefore unacceptable for export to some countries.

4.5 Special precautions for use, including special precautions to be taken by the person administering the medicinal product to animals
Special precautions for use in animals 
The vaccine should not be administered within two weeks of breeding as this may reduce conception rates. This may be due to handling stress rather than a specific vaccine effect. Such effects are transient, are unlikely to be above 10% and are minor when compared with the potential overall increase in conception rates demonstrated in Leptospira hardjo infected herds. However, it should be considered when timing A.I. especially with valuable semen. 
Maternally derived antibody may interfere with the performance of the vaccine in young animals. Refer to section 4.9 for appropriate dosing recommendations.

Special precautions to be taken by the person administering the veterinary medicinal product to animals 
In the case of accidental self-injection, wash the area immediately with water. If symptoms develop, seek medical attention showing a copy of the product literature. 
Even though animals may have been vaccinated it should be remembered that no vaccine is 100% effective and that the risk, albeit very much reduced, of transmission of leptospirosis from cattle to their handlers, 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 transient rise in temperature of 1 – 1.3°C lasting 24 - 48 hours after vaccination may occur, particularly after the second dose. This reaction is very common. 
Administration of the first and second dose may produce swellings in most animals with diameters of up to 7.5 and 8.5cm respectively. These local reactions normally resolve over several weeks after administration, but may persist for longer in a small number of animals. Local reactions are very common. 
Occasional hypersensitivity reactions may occur. In the case of hypersensitivity the use of adrenaline or other appropriate treatment is recommended. 
Youngstock vaccination: The sizes of the reactions seen in the second primary course may be larger than those seen in the first primary course (up to 17cm after 5 vaccinations 28 days apart). There may also be an increased sensitivity at the injection site compared to the primary vaccination. Animals may also exhibit a transient rise in temperature of 1.2 - 2.6°C following the second primary course. See section 4.9 for dosing recommendations.

4.7 Use during pregnancy, lactation or lay
Can be used during pregnancy but should not be administered within two weeks of breeding (see section 4.5).

4.8 Interaction with other medicinal products and other forms of interaction
Safety and efficacy data are available which demonstrate that this vaccine can be administered to animals of 8 month of age or older on the same day, with Bovilis BVD vaccine. The two vaccines should be administered at separate sites. For the concurrent use of Leptavoid H and Bovilis BVD vaccines in naïve animals, the primary vaccination course must be completed at least 4 weeks before the expected gestation, in order that foetal protection can be established.

No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the product mentioned above. 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: Cattle 2 ml. 
Minimum age of administration: 1 month

By subcutaneous injection. The container should be well shaken to resuspend the precipitate before doses are withdrawn. The vaccine should be deposited beneath the skin covering the chest wall, well behind the shoulder, or beneath the skin covering the side of the neck. 
Syringes and needles should be sterilised before use and the injection made subcutaneously through an area of clean, dry skin taking precautions against contamination. Exercise care with part used containers and discard all part used containers within 8 hours of opening to reduce the potential for contamination.

Dosage schedule:
The primary course consists of two doses with an interval of at least 4 weeks and not more than 6 weeks between them. Ideally the course should be completed in the spring before the main season of transmission of Leptospira hardjo.

Booster vaccination: 
Re-vaccination with a single dose should be given annually to maintain protection against infection and progressively reduce exposure in the herd.

If the primary course is given later than the spring, the first booster should be given in the following spring and annually thereafter.

Youngstock vaccination:
If the calves are inoculated before 5 months of age, a further primary course should be given at that age (allowing an interval of 4 weeks between vaccinations), as otherwise maternally derived antibodies may interfere with the immune response.

Older calves not immediately exposed to infection can be given the initial course at any time, but it is advisable to complete vaccination shortly before the main season of transmission of leptospirosis.

To improve herd fertility:
For maximum benefit the primary course should be completed within 12 months of infertility being diagnosed as caused by Leptospira hardjo.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary 
A greater proportion of animals may show a transient rise in temperature of 1 - 2°C lasting 24 - 48 hours after an overdose administration. Injection site swellings are similar to those seen with a single dose.

4.11 Withdrawal period
Zero days.

To stimulate active immunity against Leptospira interrogans serovar hardjo and Leptospira borgpetersenii serovar hardjo.
