Automatic EcoFlex cooler returns

Effective immediately, McKesson has a new process for returning EcoFlex coolers after you receive your UUAV vaccine shipment. UPS will automatically schedule a pickup for empty EcoFlex coolers within one to two business days after vaccine delivery. Providers no longer need to initiate a manual pickup request by phone or online. Vaccine shipments will also contain flyers detailing this new process.

Coolers will still contain standard return shipping labels, and providers can still use these labels to send coolers back through standard shipping channels if they prefer not to wait for the new UPS auto-pickup.

Locations where the UPS label process is not available will continue to follow their current cooler return procedures.

If your vaccine shipment arrives in a KoolTemp cooler, the cooler and any packing materials can be disposed of because these do not need to be returned to the warehouse.
