"After months of preparation and close planning with McKesson, Operation Warp Speed and state and local officials, the Covid-19 vaccines will begin moving to dosing centers throughout the United States," said a FedEx press release.
FedEx SenseAware ID, a Bluetooth low-energy sensor device, will be affixed to vaccine shipments, which was also done to the Pfizer vaccine shipments distributed across the US last week, according to the delivery services company.
The SenseAware ID will ensure the "temperature-sensitive deliveries move swiftly and safely through the FedEx Express US network with FedEx Priority Overnight service," said the release.
