Facts & Figures
Current BVD eradication options
Ongoing BVD control schemes aim to: (i) prevent the introduction of BVD virus (including live or inactivated vaccines) in free herds; (ii) remove PI animals from infected herds; (iii) monitor BVD status over time. Eradication programmes in the EU have been applied variously at national, regional and herd level.
Management strategies in the EU1
Essentials for a successful BVD management strategy:
- Removal of PI animals before vaccination
- Vaccination of cattle must induce broad and log-lasting immunity
- vaccination of female cattle must confer foetal protection and must be safe
during pregnancy - Promotion of safe trade
- Surveillance
Current vaccination options in the EU1
- *use during pregnancy should only be on a case-by-case basis decided by the responsible veterinarian
- L2D (Life-double-deleted) is a special version of modified live vaccines that combines efficacy of a modified live BVD vaccines and the safety of inactivated BVD vaccines.
