Chicken Newcastle Disease and Avian Influenza (H9 subtype) Bivalent Inactivated Vaccine (LaSota strain WD strain). The Newcastle disease component preferentially uses the LaSota strain, combined with highly homologous strains of Newcastle disease circulating in China, effectively stimulating local mucosal immunity in the respiratory tract and humoral immunity. The H9 subtype avian influenza component uses the WD strain, which has high homology with the currently prevalent H9.4.2.5 dominant strain, providing good cross-protection and a high protection rate of up to 94.4% against H9 subtype avian influenza virus isolates from different years.

·    Strain Preference: WD strain has high homology with the currently prevalent H9.4.2.5 dominant strain, providing good cross-protection

·    Multi-Strain Synergistic Immunity: Single-embryo inoculation with individual antigen, no immune interference between strains, rapid immune response, high antibody titers

·    Purified Antigen: Through antigen concentration technology and new adjuvant technology, the vaccine’s immunizing dose is significantly reduced, minimizing stress on the chickens

·    High Inactivated Antigen Content: Both Newcastle disease and avian influenza antigens are more than 5 times the standard content

Usage and Dosage: Suitable for chickens of any breed and age. Subcutaneous or intramuscular injection in the neck. For chickens under 4 weeks old, 0.3ml per chicken; for chickens over 4 weeks old, 0.5ml per chicken.

Packaging Specification: 250ml/bottle

Usage Case: The WD strain of H9 subtype avian influenza provides a high protection rate of up to 94.4% against H9 subtype avian influenza virus isolates from different years.
