A delivery system for delivery of a fluid agent, the delivery system comprising:

• a blow-fill-seal (BFS) vial containing a single dose of a fluid agent, the BFS vial defining a cylindrical neck and comprising at least one shaped radial protrusion;
• and
• a delivery assembly configured to be securely coupled to said BFS vial and to deliver said single dose of said fluid agent, said delivery system comprising:
• a hub member having a proximal end defining an inlet port and a distal end defining an outlet port and a channel providing a fluid pathway from said inlet port to said outlet port, said inlet port having a connection fitting configured to receive and retain the shaped radial protrusion of the BFS vial thereto, said inlet port configured to receive the fluid agent from the BFS vial;
• and
• an administration member for administering said fluid agent into a patient, said administration member being retained by the hub member.
