The terms “drugs” and “devices” were selected to be part of the legislation because they're defined in the Food and Drugs Act. As the name suggests, “drugs” refers to your typical vaccines and therapeutics. “Devices” was included to be very pragmatic. When the facility produces vaccines, just pragmatically, they will need to be put into something. “Devices” refers to things like vials and syringes.
