Pfizer is building an ambitious supply chain and distribution system to deliver hundreds of millions of doses of COVID-19 vaccine to vaccination sites in three days.
The vaccine is manufactured in Kalamazoo, Michigan and Puurs, Belgium at a rate of 7.6 million doses daily. Shipping containers that can keep the loaded doses at a temperature of -100 Fahrenheit for up to 10 days are used to transport doses from the manufacturing sites to nearby airports as cargo on planes from FedEx, UPS, and DHL.
These carriers are also responsible for trucking doses from airports to vaccination sites such as hospitals.
