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).
