A syringe comprises a storage chamber for a vaccine, and a needle or cannula. The needle (64) is attached to a holder (53), and the latter borders the syringe housing (50). A dosing or cylinder chamber (51) with a variable volume, is located between the holder and the syringe housing, and is in contact with the storage chamber and the cannula via a valve (60,62).
