K Vac IB

Avian Infectious Bronchitis Disease Vaccine

  Inactivated and concentrated oil emulsion vaccine for chickens and breeder hens to immunize against Infectious Bronchitis Disease.


  • K Vac IB is produced with high titering Massachusetts strain of Infectious Bronchitis disease virus derived from embryonated chicken's egg, suspended in a stable oil emulsion. A large amount of antigen is provided in a 0.5 ml dose.
  • This is the most serious and common bronchitis strain that infect chicken flocks. When injected, the oil emulsion controls the absorption of the virus and greatly enhances the development of high levels of immunity.


Each dose contains not less than a pre-inactivation titer of 106.9 EID50 of avian Infectious Bronchitis disease virus.   


  • K Vac IB has been developed for use in chickens and breeder hens to give broad protection against Infectious Bronchitis disease. When injected, the vaccine produces a high level of circulating antibody (humoral immunity) which is maintained through out the production cycle.
  • It provides high level of parental immunity in the progeny. This is the only way to provide protection to the chick during the critical first few days of life. Infection with bronchitis during the egg production cycle causes loss of egg production and decreases the profitability of the flock.   


  • K Vac IB provides a broader range of protection than other commercial vaccines. This killed virus vaccine in oil emulsion provides more consistent high titers throughout the production period than the live virus vaccines.
  • The IB virus is very contagious and can recycle within the flock. This can cause loss of egg production without symptoms. K Vac IB protects the reproductive system against homologous strains and prevents such egg losses .
  • K Vac IB is completely safe because it contains no living virus. It can safely be administered at any age.
  • It can not spread from vaccinated to susceptible flocks or be transmitted from dams to progeny. It provides high and persistent levels of antibody in the dams to provide parental immunity to the progeny.
  • Infectious Bronchitis disease immunity is delivered to the farm with the chicks.

Dosage & Use

  • Birds should be "primed" withmild or intermediate strains of live virus bronchitis vaccine at least 4 weeks prior to the use of this vaccine
  • Vaccinate with K Vac IB at 16 to 20 weeks of age. If birds are held for a second year, revaccinate during molt.
  • Dosage is 1/2 ml (0.5 ml) per bird.
  • Vaccine should be brought to room temperature (+18°C to +20°C) before use.
  • Inject subcutaneously in the lower neck region using aseptic technique. inject all birds in flock
