Watch: From Kalamazoo to Fenway Park: the logistics of Covid-19 vaccine shipments

Covid-19 vaccinations in the Unites States are starting to accelerate after a slow rollout. The U.S. is now vaccinating approximately 2 million people per day. President Biden has promised the country will have enough supply to vaccinate all Americans by the end of May.

Deploying vaccinations on this scale is a massive logistical undertaking. Physically moving the vials from their manufacturing sites to the people that need them takes both cutting-edge technology and precise planning. Watch the video above to see what it takes to deliver these critical shipments, by tracing a dose from its factory in Kalamazoo, Mich., to an arm in Boston.
