Infectious bursal disease vaccine live

Gumboro Vaccine Description

This live trivalent vaccine is formulated with three infectious bursal disease virus (IBDV) strains (B87, CA, and CF), providing broad-spectrum protection against both classical and variant strains of Gumboro disease.

Infectious bursal disease is a highly contagious viral infection that damages the bursa of Fabricius, leading to severe immunosuppression, increased susceptibility to secondary infections, and reduced vaccine response to other diseases.

The inclusion of multiple strains enhances cross-protection against diverse field variants, which is critical in regions with complex epidemiological patterns. Compared with single-strain vaccines, this multivalent formulation provides more reliable protection under varying maternal antibody levels and field challenges.

The vaccine is suitable for flexible administration methods, including eye drops, nasal instillation, and drinking water, making it adaptable for different farm scales and management systems.
