【COMPOSITION AND CONTENT】
This product contains live Newcastle Disease Virus Strain La Sota (CVCC AV1615) and live Infectious Bronchitis Virus Strain H52 (CVCC AV1513). The viral titer of Newcastle Disease Virus is no less than 10⁶·⁰ EID₅₀ per dose, and the viral titer of Infectious Bronchitis Virus is no less than 10³·⁵ EID₅₀ per dose.
【CHARACTER】
Milky white porous sponge cake, readily detachable from the inner wall of the vial; dissolves completely and rapidly after reconstitution with diluent.
【INDICATIONS】
For the prevention of Newcastle disease and avian infectious bronchitis in chickens
【DOSAGE AND ADMINISTRATION】
Inoculation via nasal dropping or drinking water administration. Suitable for chickens aged 21 days and above. Dilute the vaccine with normal saline, water for injection or high-quality cold boiled water according to the dose specified on the vial label.
Nasal Dropping Inoculation: 1 drop (0.03 mL) per chicken.
Drinking Water Inoculation: Double the dosage. The water consumption varies according to chicken age: generally 10–20 mL per chicken for chickens aged 20 to 30 days, and 20–30 mL per chicken for adult chickens.

Shelf life: 18 months from the date of manufacture.
For use only under veterinary supervision.
1. Dual classic strain combination prevents two diseases with one dose: Scientifically compounded with classic Newcastle disease La Sota strain and infectious bronchitis H52 strain. With stable virulence and strong immunogenicity, the vaccine prevents two major respiratory diseases simultaneously, simplifies epidemic prevention procedures and reduces breeding costs efficiently.
2. Ultra-high dual virus titer ensures powerful immune response: The vaccine contains balanced high-titer dual antigens, meeting strict titer standards for both Newcastle disease and infectious bronchitis. It activates dual specific immunity rapidly, induces high-level protective antibodies, and builds a solid dual respiratory immune barrier for chicken flocks.
3. Optimized for chickens over 21 days old for booster immunization: Specially developed for young and adult chickens above 21 days old, it serves as a core booster vaccine after H120 primary immunization. It effectively supplements basic antibodies, fills the late-stage immune gap and avoids recurrent respiratory diseases.
4. Dual vaccination methods adapt to full-scale farm epidemic prevention: Supports nasal drip and drinking water vaccination. Nasal drip ensures accurate dosage and uniform antibodies for precise immunization, while stress-free drinking water vaccination is highly efficient for large-scale universal immunization of intensive chicken farms.
5.High-quality freeze-dried formulation for uniform and accurate vaccination: The loose sponge-like mass dissolves rapidly and completely without caking or residue. The uniform medicinal liquid ensures consistent dual-antigen dosage for each chicken and balanced herd immune level.
Q: What type of vaccine is this? What diseases does it prevent?
A: This is a combined live vaccine for Newcastle disease and infectious bronchitis, a non-prescription veterinary drug compounded with two classic attenuated strains. It is specially used to prevent two major avian respiratory diseases and serves as the core booster vaccine for middle and late-stage chicken flocks.
Q: What are the core advantages and protection characteristics of the vaccine?
A: The vaccine realizes dual disease prevention with one dose, featuring high-titer dual antigens and stable protection. It is optimized for booster immunization of chickens over 21 days old, perfectly connecting the H120 primary immunization procedure. With flexible vaccination methods and ultra-long shelf life, it adapts to daily epidemic prevention of large-scale poultry farms.
Q: What are the applicable chickens, vaccination method and standard dosage?
A: Applicable to healthy chickens of all breeds over 21 days old. For nasal drip vaccination, dilute according to labeled doses and administer 1 drop (0.03mL) per chicken; for drinking water vaccination, double the dosage, with 10–20mL water per 20–30-day-old chicken and 20–30mL water per adult chicken.
Q: What is the usage time limit for diluted vaccine?
A: Store the diluted vaccine in a cool and dark place and use up completely within 4 hours. Overtime use is prohibited to prevent virus attenuation, vaccine failure and substandard immune protection.
