The vial has a body, a storage chamber within the body for storing multiple doses of the substance therein, a sterile filter configured to sterilize air or other gas flowing into the storage chamber through the filter, and a one-way valve connectable in fluid communication with a syringe or other delivery device. The one-way valve is moveable relative to the body between first and second positions (i) one of which permits the valve to open so that substance from the storage chamber can flow therethrough and into the syringe or other delivery device connected in fluid communication therewith, and (ii) one of which prevents the valve from opening.
