Vaccination regime
Primary course
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.
Re-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.
