Vaccination can be a valuable management tool, especially when combined with management practices to avoid transmission to herd replacements, testing and prevention of Johne’s introduction through outside sources.
Vaccination can reduce and help prevent:
Clinical signs and gross lesions
Fecal shedding (reduce the number of organisms shed and length of time shedding occurs)
Vaccination is Available through the
Iowa Department of Agriculture and Land Stewardship
To obtain approval, in cooperation with your herd veterinarian, the following steps must be completed:
1. A Vaccination Agreement must be completed and signed by the Herd Owner, Herd Veterinarian, District Veterinarian and State Veterinarian.
2. Vaccine is only for use in known infected herds (positive organism-based test).
3. A whole herd tuberculosis (TB) test is required before vaccination approval and any herd additions must undergo TB testing.
4. Vaccine may only be used in calves 1 - 35 days of age and administered by an accredited veterinarian.
5. Vaccinated calves are tattooed and identified (record of vaccination is submitted to Iowa Department of Agriculture and Land Stewardship).
