A prefilled syringe is disclosed that includes a barrel, a stopper displaceable within and defining a sealed chamber in an interior of the barrel, a liquid filled in the chamber of the barrel, and a plunger extending within the barrel. The stopper expels the liquid out of the barrel via an orifice when being forwarded towards the orifice by the plunger such that a volume of the chamber is reduced. The plunger includes a proximal portion, a distal portion and a rod portion extending between the proximal portion and the distal portion. The plunger is shaped to form a pathway between an opening of the barrel and a segment where the proximal portion of the plunger is neighboring the stopper such that a sterilizing agent can be provided through the opening of the barrel to the segment where the proximal portion of the plunger is neighboring the stopper.
