The most ambitious vaccine campaign in U.S. history is about to begin. This weekend, 2.9 million doses of the coronavirus vaccine developed by Pfizer and BioNTech are set to travel by plane and guarded truck from Michigan and Wisconsin to designated locations, mostly hospitals, in all 50 states. Pfizer said the first shipment would leave its Kalamazoo, Mich., plant, above, early Sunday morning. The first injections are expected to be given by Monday to high-risk health care workers. FedEx and UPS will transport the vaccine throughout most of the country, and each delivery will be followed by shipments of extra dry ice a day later (the vaccine needs to be kept at minus 94 degrees Fahrenheit).
