Each dose of vaccine contains at least 10⁶ EID₅₀ of the Newcastle Disease vaccine virus strain Clone 30. The vaccine pellet contains stabilisers and gentamycin.

A. Spray Method

The vaccine should be dissolved in cool, clean, non-chlorinated water which is free from iron and chlorine. The vials 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 – 40 cm, preferably when the chickends are sitting together in dim light.

Dissolve 1 000 doses per litre of water and set the nozzle to produce fine droplets falling like fine rain, (aerosol generators should be used only when this is known to be safe in chickens).

B. Eye Drop Application

Dissolve the vaccine in Diluent Oculo-Nasal may be used. Administer by means of a standardised dropper (usually 30 ml per 1 000 doses). One drop should be applied from a height of a few centimetres onto one eye. The eye drop should be allowed to spread across the surface of the eye.

The diluent contains a dye (patent blue) which allows an easy check on the correct vaccination. Do not release the chickens until a swallowing motion is noticed.

Vaccination Programme

The optimum time and method of administration depends largely upon the local situation. Therefore the advice of a veterinary surgeon should be sought. The vaccine is safe to use from day 1 of age onwards.
