A live attenuated, freeze-dried vaccine, indicated for the immunisation of fowls against the Massachusetts type of serologically related types of Infectious Bronchitis and against Newcastle Disease.




  • Vaccinate healthy chickens only.
  • Wash and disinfect hands and equipment after vaccination.
  • Observe aseptic precautions.
  • Ensure that the vaccination equipment (spray apparatus, droppers) is clean prior to use.
  • The spray apparatus should be free from sediments, corrosion and traces of disinfectants and/or spirits. It should preferably be used for vaccination purposes only.
  • Avoid contamination with traces of disinfectant or spirits.
  • It is good vaccination practice when handling the vaccine to avoid contact with the eyes, hands and clothing.


Spray Method

  • The vaccine should be dissolved in distilled water.
  • The vial of freeze-dried vaccine should be opened under water.
  • The spray apparatus should be free from sediments, corrosion and traces of disinfectants (preferably to be used for vaccination purposes only).
  • The vaccine medicated water should be spread evenly over the correct number of chickens, at a distance of 30 to 40 cm, preferably when the chickens are sitting together in dim light.
  • For 1-day-old chickens use 0,25 ℓ of water/1 000 birds and set nozzle to produce a course spray, falling like rain.
  • For older chickens, dissolve 1 000 doses/ℓ of water and set the nozzle to produce course spray. (Aerosol generators should be used only when this is known to be safe to chickens).

Eye Drop Application

  • Dissolve the vaccine in Intervet Diluent Oculo/Nasal and administer by means of a standardised dropper (usually 30 mℓ/1 000 doses).
  • One drop should be applied from a height of a few centimeters onto 1 eye. As an eye drop application, the drop should be allowed to spread evenly across the surface of the eye.
  • Do not release the chicken until a swallowing motion is noticed.
  • For numbers of birds between standard dosages, the next high dosage should be chosen.

Note: Administration by coarse spray or eye drop route gives the best response. These should be the methods of choice, especially when vaccinating young chickens.
