in a killed virus vaccine like vira shield, it tells you on the bottle to use all the contents when opened. what happens to it if you keep it. i have in the past kept a half a bottle instead of throwing it away. just wondering how big a deal that is. actually if my memory serves me right, :lol: :roll: , i think about every kind of vaccine i have ever used has said that on the bottle.
