Airlines are joining the fight against the coronavirus.
The long wait for a vaccine may be over, but distributing it to the 7.8 billion people around the world is the next big challenge. In the U.S., both the Pfizer-BioNTech and Moderna Covid-19 vaccines require two doses that will eventually need to reach the nation's roughly 330 million people.
Even though shipping is only one part of the journey, it's a critical step. DHL and McKinsey estimate vaccinating the world will require up to 15,000 flights. In the U.S., airlines have stepped up to become a crucial part of the supply chain alongside logistics giants like UPS, FedEx and DHL.
Airlines carrying pharmaceuticals and vaccines is not a new idea, but the scale and speed at which the Covid-19 vaccines must be delivered makes it a more complicated endeavor.
