A vial access adapter for withdrawal of a medical fluid contained in a vial which includes a vial access adapter body having a circular top wall with a plurality of vent holes, a circular second wall spaced from the top wall, and a cylindrical side wall which walls define a chamber for holding an anti-bacterial filter. A first spike centrally located in the vial access adapter body extends through the top wall, chamber, and bottom wall, with one end extending above the top wall terminating in a threaded luer connector, while the other end terminates in a sharp point. A flow channel extends through the first spike designed for withdrawal of the medical fluid from the vial. A second spike positioned parallel to the first spike extends from the second wall, one end of which extends into the chamber, and the other end terminates in a sharp point. A flow channel extends through the second spike designed for air flow from the chamber into the vial. An elastomeric membrane positioned within the threaded luer connector seals the opening in the vial access adapter. Preferably the elastomeric membrane is of M-shaped configuration capable of flexing under pressure and of re-sealing itself after being pierced by a luer connector or a syringe equipped with a luer connector.
