This product contains live Porcine Reproductive and Respiratory Syndrome Virus Strain HuN4-F112. The viral content is no less than 10⁴·⁵ TCID₅₀ per dose.
Pale yellow spongy loose mass, easily detached from the bottle wall and rapidly soluble after adding a diluent.
For the prevention of highly pathogenic porcine reproductive and respiratory syndrome (highly pathogenic porcine blue ear disease) in pigs. The immune duration lasts 4 months.
Administer via intramuscular injection in the neck. Dilute the vaccine with sterile normal saline to 1.0 mL per dose according to the dose specified on the vial label, and administer 1.0 mL per pig.
5 doses/vial, 10 doses/vial, 20 doses/vial, 30 doses/vial
Store at ≤ -20 °C. Shelf life: 18 months from the date of manufacture.
For use only under veterinary supervision.
1.Precise prevention against mainstream PRRS epidemic: Adopts the classic HuN4-F112 attenuated strain matching prevalent highly pathogenic PRRS strains in China, targeting sow abortion, piglet respiratory diseases and high mortality caused by PRRS.
2.High-standard antigen content for stable protection: The virus content is 10⁴·⁵ TCID₅₀ per dose. Sufficient standard antigen effectively activates specific immune response and builds a solid protective barrier with stable batch quality.
3.Pure technology and high safety with low stress: The mild attenuated strain causes no routine adverse reactions after standard vaccination and does not affect pig growth and feeding.
4.Simple and efficient for large-scale vaccination: Adopts conventional neck intramuscular injection with simple dilution operation. The loose soluble formulation facilitates rapid dilution and batch vaccination in large-scale pig farms.
5.Targeted prevention and standardized immune scheduling: It avoids immune interference with classical swine fever vaccines through staggered vaccination. Clear applicable groups, forbidden scenarios and slaughter withdrawal period ensure scientific farm immunization management.
A: This is a live vaccine for highly pathogenic porcine reproductive and respiratory syndrome (Strain HuN4-F112), a non-prescription veterinary drug, specially used to prevent highly pathogenic PRRS
Q: What is the virus content standard of the vaccine? What are its immune advantages?
A: The virus content is no less than 10⁴·⁵ TCID₅₀ per dose. Sufficient effective antigen stably activates immunity and produces targeted antibodies to resist HP-PRRS virus infection with stable and reliable prevention effects.
Q: What are the inoculation method, dosage and applicable pig groups?
A: Only applicable to healthy pigs over 3 weeks of age. Perform neck intramuscular injection with 1ml per head after dilution with sterile normal saline. Negative pig herds, breeding pigs and pregnant sows are prohibited from vaccination.
Q: Can this vaccine be vaccinated simultaneously with classical swine fever vaccine?
A: No. The two vaccines should be used at an interval of at least one week to avoid immune interference, poor antibody production and reduced immune efficacy.
Q: What are the key requirements for vaccine dilution, storage and transportation?
A: Avoid high temperature, disinfectants and direct sunlight during storage and transportation. Keep diluted vaccine away from high temperature and use it within 1 hour to guarantee viable vaccine activity.
Q: What specifications, storage conditions and shelf life does the vaccine have?
A: Four specifications (5/10/20/30 doses per bottle) are available. Store below -20℃ with a shelf life of 18 months, suitable for regular reserve in various pig farms.
