Freeze-dried live vaccine against Newcastle disease
PROPERTIES: BIO-VAC CLONE is prepared using the clone CL strain of Newcastle disease virus, cultured on embryonated SPF eggs, freeze-dried and vacuum-sealed. The reactions of this vaccine are more pronounced than those of the Hitchner B1 strain. It is therefore recommended to revaccinate birds, already inoculated with BIO-VAC B1. In any case, the immunity given by the cloned strain is stronger and lasts longer, which makes it the vaccine of choice in endemic areas.
COMPOSITION: 1 dose of vaccine contains: not less than 106.5 EID50.
INDICATIONS: Prophylaxis of Newcastle disease.
