Eye Drop Method

Reconstitution
Whenever available clean water containing 2.5 grams of instant skim milk powder per litre should be used as a diluent for reconstitution.
The vaccine should be prepared immediately before use by tearing the cap off the vial, removing the rubber stopper and resuspending the virus with pre-chilled diluent. After shaking, the reconstituted vaccine is poured into the 3-5 litres of skim milk solution (2.5 grams of instant skim milk per litre of chilled water).
Vaccination delivery may be via drinking water lines or direct dispensing to drinkers.
Early morning administration is recommended.
See pack instruction sheet for detailed notes on application and administration.
