1. A vial adapter for a closed fluid transfer system, the vial adapter including: a base defining an opening having a plurality of retainers extending around the opening of the base and being configured to snap-fit connect to a neck of a vial, the base defining a lower inner annular rim and an outer annular rim and a cavity therebetween;a cover supported on the outer annular rim of the base, wherein an expansion chamber is defined within the cover and the base;an adapter support situated within the cavity of the base, the adapter support including: an annular flange for seating on the lower inner annular rim of the base and forming a fluid tight seal therebetween;an annular wall extending from the annular flange and defining an upper inner annular rim, wherein the cover is also supported on the upper inner annular rim;a male stem extending in a first direction from the annular flange;a male stem for selectively connecting to and insertion into an open distal end of a syringe adapter, the male stem defining a lumen extending therethrough;a pair of opposed guide pins extending radially outward from the male stem;a pair of opposed guide surfaces extending radially outward from the male stem at a location proximal of the guide pins and being in registration with the guide pins; anda seal extending across the lumen of the male stem; anda spike extending in a second direction from the annular flange, wherein the spike extends into the opening of the base, wherein the spike includes a first lumen being in fluid communication with the lumen of the male stem, and wherein the spike includes a second lumen being in fluid communication with the expansion chamber; anda bladder extending between the upper inner annular rim and the outer annular rim of the base. 2. The vial adapter according to claim 1, wherein the spike of the vial adapter penetrates a septum of the vial upon a connection of the base of the vial adapter to a neck of the vial. 3. The vial adapter according to claim 1, wherein each the seal is made from polyisoprene. 4. The vial adapter according to claim 1, wherein the vial adapter is configured to move a syringe adapter from a closed state to an open state, the syringe adapter including: a housing defining an open distal end and an open proximal end, the housing defining a pair of opposed longitudinally extending slots opening from the open distal end of the housing, the housing including a pair of opposed longitudinally extending ribs projecting from an inner surface thereof;a base supported in the open proximal end of the housing and including the syringe adapter luer connector;a collar slidably and rotatably supported in the housing, the collar defining a longitudinal opening therethrough, the collar defining a pair of opposed L-shaped tracks formed in an outer surface thereof and configured to receive a respective longitudinally extending rib therein, the collar defines a pair of opposed helical tracks opening from a distal surface of the collar, the opposed helical tracks being aligned with a respective slot of the housing when the collar is in a distal-most position;a shuttle slidably extending through longitudinal opening of the collar, the shuttle defining a shuttle lumen extending longitudinally therethrough;a barrel supported on and extending over a distal end of the shuttle, the barrel defining a central opening aligned with the shuttle lumen; anda biasing member interposed between the collar and the shuttle for urging the collar away from the shuttle;a syringe first adapter seal being interposed between the shuttle and the barrel, wherein the syringe first adapter seal extends across the shuttle lumen and the central opening of the barrel; anda needle defining a lumen therethrough, the needle having a proximal end supported in the base such that the lumen of the needle is in fluid communication with the luer connector, the needle having a sharpened distal tip disposed within the lumen of the shuttle when the shuttle is in a distal-most position;wherein the vial adapter moves the syringe adapter from the closed state to the open state upon:inserting the guide pins of the male stem of the vial adapter into the respective slots of the housing of the syringe adapter, whereby the seal of the vial adapter abuts the seal of the syringe adapter;advancing the male stem of the vial adapter into the open distal end of the housing such that the guide pins enter into the respective helical track of the collar to (1) rotate the collar relative to the housing of the syringe adapter and (2) align the ribs of the housing with a through portion of the collar; andfurther advancing the male stem of the vial adapter into the open distal end of the housing causing the collar to move proximally which causes the shuttle to move proximally until the tip of the needle penetrates through the abutting seals, whereby the syringe adapter is in the open state and fluidly interconnects the syringe with the vial adapter. 5. The vial adapter according to claim 4, wherein when a syringe is connected to the syringe adapter, and when the syringe adapter is connected to the vial adapter, and when the vial adapter is connected to the vial, the syringe is in closed fluid communication with the vial. 6. The vial adapter according to claim 5, wherein when the syringe is connected to the syringe adapter, and when the syringe adapter is connected to the vial adapter, the tip of the needle of the syringe adapter penetrates the abutting seals of the syringe adapter and the vial adapter and when the vial adapter is connected to the vial, the syringe is in closed fluid communication with the vial. 7. The vial adapter according to claim 5, wherein air from the syringe is injectable into a cavity of the vial adapter defined between the bladder, and the base and the adapter support, through a fluid passage defined by the needle of the syringe adapter, the lumen of the male stem, the first lumen of the spike, the vial and the second lumen of the spike. 8. The vial adapter according to claim 4, wherein each seal is made from polyisoprene.
