A single dose of vaccine to be administered by nebulization at 14 days of age.

The vaccine should be reconstituted in demineralised or distilled water (3 to 5 ml) then diluted in a volume appropriate for the type of spraying equipment to be used and the number of doses to be administered. Spray equipment should be used which is capable of consistently producing droplets of average diameter 80 – 150 μm. The vaccine should be sprayed as evenly as possible over the birds to ensure that each bird receives a full dose. Further information on appropriate equipment can be obtained from the manufacturer.
