A fluid transfer device for accessing fluid from vials and ampoules includes a cannula assembly including a cannula having a lumen therethrough connected to a hub having an open proximal end. A filling straw includes a proximal end, a distal end, and a passageway therethrough. The straw further includes a needle portion at the distal end and a shaft portion between the needle portion and the proximal end. A cutting edge is provided at the distal end of the needle portion for piercing a vial stopper. The cannula assembly is removably engaged with the filling straw so that the open proximal end of the hub is in fluid communication with the passageway of the filling straw. An elongate shield having an open proximal end, an open distal end and a side wall therebetween defining a recess in the shield. The shield is removably connected to the straw so that the shaft portion and the needle portion of the straw are contained within the recess. A seal plug having a proximal end and a distal end is provided. The seal plug has a distal position with respect to the shield wherein the seal plug projects distally outwardly from the distal end of the shield for telescoping movement from the distal position to a proximal position wherein the seal plug seals the needle portion to prevent unpressurized fluid communication between the passageway and the exterior of the shield.
