Retailers Already Fear US Holiday 'Shipageddon'; Now Here Come Vaccines Reuters LOS ANGELES - Deliveries of holiday gifts purchased online at major retailers could get delayed by something far more critical -- COVID-19 vaccines. Pharmaceutical companies, including Pfizer and Moderna, as early as mid-December could begin sending inoculations to U.S. health care workers and nursing home residents. FedEx and United Parcel Service could make space for those shipments on cargo planes by bumping off packages from Amazon.com, Walmart, Target and other retailers. "FedEx is prioritizing vaccines," company spokeswoman Bonny Harrison told Reuters. While vaccines could displace some FedEx Express air shipments, they will not affect the separate FedEx Ground network that depends on trucks and delivers the majority of the company's holiday volume, Harrison said. .
