How does the vaccine supply chain work?
The first step in the vaccine supply chain is manufacturing.
The Pfizer vaccine which is intended for the UK is being manufactured in Belgium.
The vaccine is produced in vials, each containing around five doses, diluted with standard pharmaceutical-grade saline solution.
The vials are placed in trays of around 100 each and placed into trays which are then kept at -70C.
The freezer boxes contain between 1,000 and 5,000 doses each and are kept cold with dry ice in insulated wall panels.
